Nie lubię Gophera:P ale skoro jest systematycznie rozwijany (obecnie chyba nawet częściej od Stelli), to znaczy, że jestem w mniejszości. Stella ma całkiem rozwiniętego konkurenta, który jak większość multiplatformowych aplikacji potrafi doprowadzić mnie do szewskiej pasji kiedy chce załadować gry z innej partycji;) Po za tym, to całkiem przyjemny emulator ATARI 2600 (w naszym kraju zasłynęła ta konstrukcji dzięki klonowi o pięknej nazwie RAMBO;)) posiadający dość dobry filtr "psujący" obraz i parę dodatkowych ustawień pozwalających na dopicowanie naszego wirtualnego VCS.
Gopher v0.23.1 06/06/2023
bug fixes
- fixed debugger "TV Screen" rewinding
- bleed through frame was wrong
- screen resizes correctly when rewound
- rewind no longer crashes at reset boundaries
- under certain conditions the program would panic because of missing rewind entries
Gopher v0.23 29/05/2023
Kangaroo (1983, Atari)
Changes from v0.22.0
playmode
- improved rendering stability
- applies when monitor is similar in refresh rate to emulated TV
- opengl VSYNC "immediate updates" will synchronise with timer
- this may improve performance on some systems

- artefacts were particularly noticeable in games with flicker kernels
screenshots
- added new composite screenshot mode
- composite is very good at capturing motion on the screen
- activated with CTRL-F12
- other screenshot modes renamed to 'single' and 'motion'
- activated with F12 and SHIFT-F12 respectively
cartridges
- added SCABS bank switching method
ROM select window
- thumbnailer shows a smoother image
plusrom
- fixed issue with rewind "boundaries" being inserted too often
- reading from the network queue would insert a boundary
- a boundary is only needed when data is sent to the network
bug fixes
- using right mouse button to capture mouse for paddle input no longer
interferes with context menus for any open windows
Gopher v0.22 8/05/2023
Changes from v0.21.0

- reduced CPU usage when emulation is paused
- tracker
- replay selection of tracker history
- improved display
- macro system
- basic scripting of emulator input
- bug fixes
- phantom reads could trigger fastloading in CDF cartridges by mistake
- ARM 'immediate mode' switching while running could crash DPC+ and CDF
cartridges- CDFJ+ supports any sized cartridge

- stack pointer working correctly in the debugger
Gopher v0.21 13/02/2023
Changes from v0.20.0
- Performance
- significant performance increase when built with pgo file. the "release" target in the Makefile does this
- 18% for regular ROMs
- 13% for a typical ARM ROM
- DPC+ could return formatted errors on calls to Access(). this had a significant performance impact on cartridges that triggered the error
- Display
- new render pipeline
- better scaling
- screenshotting method altered
- improved input latency
- Controllers
- support for stelladaptor
- joystick and paddle only (driving controller is not yet supported at all)
- Debugger
- magnification of debugging screen
- Setup Database
- TV entry type changed. existing setup database entries will need to be altered
- Database
- entries can be commented out
- DWARF / local variables
- calculation of call frame address is now correct in more (all?) instances
- Bug Fixes
- fixed ARM memory read bug that was most likely to be encountered during DWARF parsing/loading
- WATCH command would halt on a check of an address, even when other conditions (read/write) were not met
- behaviour of STEP BACK in HBLANK area
- behaviour of random pins
Gopher v0.20 12/02/2023
Changes from v0.19.3
- DWARF Support for ARM Source
- added const types
- breakpoints can be set on executable source lines
- local variables visible when execution breaks

- simplified EF format
- cartridges can now leave pins on the data bus undriven
- implemented WD format
- Audio
- fixed obscure bug related to RSYNC
- improved stereo output
- PlusROM
- network transmission delayed in order to allow the send buffer to be overwritten by badly behaving ROMs ( this is an emulation of a bug in the PlusROM)
- improved send buffer display in GUI (receive buffer removed)
- RIOT Emulation
- small correction to RIOT register masking
- ARM Emulation
- immediate mode toggling is safe at any time
- Profiling/Performance window
- reset statistics now happens at the start of new TV frame rather than immediately
- cumulative figures option, including warnings indicating whether optimisation might affect the accuracy
- Terminal
- added SWAP command
- CARTRIDGE DUMP command (atari derived cartridges only for now)
- refined output of TRACE and WATCH commands
- added COPROC and DWARF commands
- STEP OVER no longer crashes emulation when 6507 is not at a cartridge address
- Terminal (GUI)
- insert mode fixed
- error messages on quit no longer printed to terminal. this caused the terminal to open just before the program ended, meaning the terminal would be open the next time the debugger was opened
- Timeline Window
- clearer indication of scanline jitter
- added "Save Timeline to CSV" in popup menu
Gopher v0.19.3 5/10/2022
Gopher Attack (1982, U.S Games Corporation)
- implemented CommaVid cartridge mapper
- no fingerprinting so
-mapping CVcommand line required- or, change the file extension of the ROM file to
.cv
- RIOT timer
- PA7 bit reset immediately on TIMINT access
- previously the reset was delayed to when the timer expired
- Debug Screen
- element reflector works in HBLANK when debug colours are enabled
- RAM window
- RTS prediction no longer affects debugging information for the memory subsystem.
- inm particular this fixes the information presented in the
6507 Pinoutwindow
- GUI
- window is raised and selected on mode switch
Gopher v0.19.2 28/08/2022
Harbor Escape (aka River Raid) (1983, Panda) z włączonymi efektami CRT (ale bez najnowszych, źle wyglądają przynajmniej dla mnie:P)
CRT effects
- added bevel and shine option
- both disabled by default
The rounded corners option was added in v0.19.1 but on its own it's not very effective. Applying the bevel and the shine option completes the effect. More control to both these options will be added in the future.
Gopher v0.19.1 25/08/2022
Makefile
- Apple Macs with an ARM chip will no longer use freetype font rendering
when built with the build or release targets- see issue #19
Display
- changed relationship between the frame rate limiter and monitor
synchronisation. this may result in a performance improvement on some systems- uncapped FPS no longer uses input buffer. this resulted in choppy visuals
- fixed visual bug seen when switching from playmode to the debugger when
one or the other mode had a "maximised" window
TIA
- missile sprites were not plumbed to player correctly after gameplay
rewinding. this affected missiles that rely on RESMPx for positioning
Rewind
- joystick and gamepad controllers resume from a neutral position after
gameplay rewind
ARM Developer
- statistics more carefully collated during rewinding to avoid spikes in
the data
CRT effect
- added rounded corners option
As of this version I will no longer be compressing the linux/amd64 version with UPX
Gopher v0.19.0 30/05/2022
small performance improvements
- uncapped frame rate increase
- 16% to 18% (6507 only ROMs)
- 13% to 16% (a typical ARM ROM)
change of WAV implementation
- this affects the loading of Supercharger tapes
- and the recording of audio to disk
- neither should be noticeable changes
Gopher v0.18.0 21/05/2022
ARM Developer
- debugging window added for global variable inspection
- collision detection of ARM stack with program variables
- static areas window improved
- clearer indication of memory addresses
- labeling of named variables in memory
- performance window improved
- raw ARM cycle values in addition to percentile values
- kernel focus (VBLANK, Visible Screen, Overscan)
- performance relative to frame
- access of address 0x00 is treated as illegal (probably null dereference)
- visualisation of CDF streams
VCS RAM and Cartridge RAM Window
- indicates labeling of addresses (using ASM symbol file)
- illustration of 6507 stack usage
Peripherals
- choice of attached peripheral can be overriden on startup
TIA bug fixes
- corrected missile reset to player position for double-width player
Savekey/Atarivox
- EEPROM window (savekey data) works correctly for AtariVox
Debugger
- BREAK NONEXE to halt execution on 6507 execution if PC address is not in the Cartridge or RAM areas
Debugger GUI
- better window management in the debugger
- window state (open/close) saved between sessions
Playmode GUI
- non-integer scaling reintroduced - improved scaling method to avoid uneven scanlines
- bugfix (Windows and MacOS)
- window repainted during window resizing meaning better visual feedback for the user
- audio can be muted (could already be muted in the debugger)
- state of FPS overlay will carried over between sessions
- "active" pause screen readded as an option (in the prefs window)
Gopher 0.17.0 07/04/2022
Changes from v0.16.0
- ARM Developer
- requirement for .obj and .map files replaced with DWARF data
- performance and source windows improved
- ARM
- improved accuracy of T1TC timer
- cycle counting corrected (by one color clock) on CALLFN exit
- clock speed definable
- AtariVox
- added support for AtariVox
- currently only supports Festival for voice synthesis
- missing some AtariVox sounds and effects
- 6507
- all 256 opcodes implemented
- SaveKey
- removed (small) performance bottleneck
- PlusROM
- update network headers to emulate firmware >= v2.1.1
- GUI
- default Dear Imgui font replaced with JetBrainsMono
- font size definable
- Documentation
- Usage documentation now in wiki
https://github.com/JetSetIlly/Gopher2600-Docs/wiki
Gopher 0.16.0 30/01/2022
H.E.R.O (Activision, Inc., 1984)
ARM
- added support for obj and map files for ARM based ROM projects requires that obj and map file to be created as part of the ROM file's compilation process
- see https://github.com/JetSetIlly/Adventureland-2600 for example of a project setup for this
- added source code, performance and illegal access window. for ROMs where obj and map files are available
- fixed: crash was possible if cart was changed from ARM to non-ARM when
- coprocessor disasm window was open - a race condition with the "lazy data" system
6507
- zero-page indexed addressing causes phantom read correctly this corrects the read values of the TIA registers (collision registers etc) when read with a zero-paged indexed instruction other addressing modes already caused correct phantom reads
RIOT
- port B is now writable from the CPU
Debugger GUI
- ports window replaces chip registers window timer window improved. fixed bug in ticks remaining display and added TIMINT field disassembly window improvements peripherals window replaces controllers window 6507 Pinout window showing the state of the address and data bus on any given color clock
Television
- audio will always play regardless of frame stability
- an extra condition testing for stability on startup meant that some ROMs never outputted sound if they never reached stability. this rarely matters but it affected the tunabit demo ROM in particular
- added 'Sync On Power' CRT option
- this will cause the screen to roll on startup
RIOT/Peripherals
- VBLANK latch bit applies only to INPT4 and INPT5
- added support for Genesis controllers
- automatic detection of controllers (using Stella fingerprints)
Cartridge Formats
- added support for EF (with or without superchip)
- cartridges with superchip now respond correctly to phantom memory
- accesses (causing phantom writes in some cases)
- tigervision (3F) now uses the correct method of switching banks
- missing Supercharger BIOS handled gracefully
Bots (WIP)
- added rudimentrary support for bots capable of playing ROMs independently. still a WIP but example bots for spacejockey and video chess have been implemented
ROM Comparisons (WIP)
- two ROMs can now be run in parallel and the output compared and differences highlighted. very specialist use and probably not of much interest
Removals
- linter. existing version was unused and underdeveloped. will reimplement in the future

Eksperymenty z obrazem - po dokładności emulacji, autorowi marzy się również jak najwierniejsze odtworzenie efektu wizualnego. Fot. Blog Projektu
Atari 2600 Emulator: Gopher v0.35.2 23/11/2024
Changes since v0.35.1
- Added cartridge mapper
- FA2
- eg. Star Castle
- non-volatile RAM for this cartridge type stored in the
nv_ramof the configuration direcotry- BF
- eg. The Realm of Riesig
- Supercharger
- Running a Supercharger game loaded from an audio file resulted in performance drop, even when the tape had stopped loading
- Performance is now equal as when loading from a fastload binary file
- Disassembly
- Disassembly is now completed in the background, leading to quicker loadtimes, particularly for very large cartridges
- Television / CRT Effects
- Blur shader is now applied more evenly
- this is most noticeable with high bloom values but produces better results generally
- Disabling the ghosting effect would cause the image to flip
- More efficient clearing of GL frame buffers
- small but significant performance improvement
- Regression testing
- Playback scripts can now be re-recorded automatically
- REDUX command now works with all regression test types
→ NOWSZY [VCS] Gopher 0.35.1 7/10/2024
Atari 2600 Emulator: Gopher v0.35.1 7/10/2024
Bug Fixes
- Some PlusROMs were not detected properly
- Only the first 1024 bytes were searched for the fingerprint, which is insufficient for some ROMs
- There is (always has been) a verification step to make sure the URL at the NMI location is correct so false positives should not be a problem
Atari 2600 Emulator: Gopher v0.35.0 2/10/2024
Bug Fixes
- Rewinding of ELF binaries caused visual artefacts on screen
- Changes to screen rendering prevented the VideoChess bot from starting
- Bug introduced in v0.31.0
- Added ELF to list of valid ROM extensions
- A file with the .elf extension would not be shown by the ROM selector
- Mouse wheel events could crash the emulator
- This affected MacOS builds on machines where mouse-wheel style scrolling is done with a touch-pad
- Replay button in tracker window could crash the emulator
Changes
- TIA audio sampled every colour clock
- This fixes problems with ROMs where the channel volume is update more than twice per scanline
- Added option to enable warning for "undefined symbols" when loading ELF ROMs
- It is possible to compile an ELF binary with undefined symbols. Rather than reject the file when it is loaded, I have chosen to allow the ROM to execute and to continue until the symbol is referenced (which may never happen)
- The addition of the warning is in addition to this behaviour and gives the developer the option of being notified of symbol errors sooner
- Added CARTRIDGE SETBANK command
- It wasn't possible previously to set the current bank of a cartridge. I had originally chosen to avoid the problem because of the high variety of ways a mapper might implement banking (if at all)
- The options to the SETBANK command vary depending on the specific mapper but generally, a mapper will expect a numeric value
Segmented mappers can take multiple numeric values. Separate values with a colon
In some instances, segments can be mapped to cartridge RAM. add an 'R' after the segment number to indicate the use of RAM. For example, the 3e mapper allows very flexible mapping of RAM
CARTRIDGE SETBANK 1R:2Some segmented mappers only allow a predefined 'pattern' of segments. In these cases the numeric value to the SETBANK command will be a pattern number. The two mappers affected by this are Supercharger and Wickstead Design
Other Changes
- Added ELF support for REL32 and PREL31 relocation
- Improved DWARF support for typedefs
- Better decision making over whether variables are in global scope
- Prevent possibility of infinite recursion in DWARF builder
Atari 2600 Emulator: Gopher v0.34.0 19/07/2024
- Changes / Bug Fixes
- Specifying a mapper will not add superchip unless asked
- ARM would sometimes loop endlessly on startup
- caused by ROMs causing execution errors and not being caught
- DPC+ and CDJF always emulate the end-of-custom-program JMP even when immediat mode is enabled
- 6507 more careful with system symbols
- system symbols no longer appear as operands for immediate instructions
- ARM yields address of most recent instruction rather than the current PC
- this isn't a problem for 16bit instructions
- but for 32bit instructions it resulted in confusing feedback in the source window- Better handling of DWARF data from alternative ELF files

→ NOWSZY [VCS] Gopher 0.33.0 6/07/2024
Atari 2600 Emulator: Gopher v0.33.0 6/07/2024
- improvements
- ELF uses less memory
- High memory usage is a direct consequence of the rewind system
- ELF memory is only recorded if it the memory block is volatile
- Recorded memory is compressed (using a very simple RLE algorithm)
- ARMv7_M architecture
- Marginal performance improvement in cycle counting
- Television can now cause emulation to break into debugger
- eg. if VSYNC is absent or too short, etc.
- Toggled via preferences window (television tab)
- FPS overlay in playmode shows VBLANK/VSYNC information
- Timeline window in debugger shows VSYNC trace
- Debugger shows break condition in toolbar
- Information shown is currently very rough
- Holding down the STEP buttons in the control window is now faster
- changes / bug fixes
- DPC+ more careful about resetting fraction fetcher counter when setting the fraction fetcher low byte
- Whether the reset happens depends on the version of the driver being emulated
- Supercharger
- Rewind fix in 0.32.0 for fastload implementation was incomplete
- Coprocessor Source Window
- Fixed parsing of comment lines
- Emulator Development
- Fixed profile targets in Makefile
- Changes made in b48d487 limited the functionality of pprof
→ NOWSZY [VCS] Gopher 0.29.1 13/03/2024
Atari 2600 Emulator: Gopher v0.29.1
- Cycle alignment for JSR instruction was broken as of v0.27.0. This release fixes that.
- The only known side-effect of the bug was a ball positioning bug in the Worm Whomper demo (by Manuel Rotschkar)
→ NOWSZY [VCS] Gopher 0.29 25/02/2024
Atari 2600 Emulator: Gopher v0.29.0
Changes from v0.28.0
GUI
- Improved font rendering
- More flexible font sizing
- ROM selector improvements
- Support for stella.pro file and libretro box art
Television
- PAL-M now generates NTSC colours rather than PAL
- Better framing of image
Other
- Emulator responds to HUP signal by reloading the current cartridge
- CoProcessor (ARM) Registers window now works with CDFJ and DPC+
- Global and Local variables can now be filtered
- Freetype rendering is no longer used in the default builds
Bug fixes
- Misbehaving ARM programs could cause a crash by accessing memory addresses that aren't represented in the emulation
- Requesting multiple composite screenshotting could cause deadlocks
- If screen size changed between requests then the compositing process deadlocked
- Paddle movement with the stelladaptor was inverted
- Bug introduced in v0.28.0
- CPU in KIL state did not tick the TIA and RIOT
- Moviecart
- ROM would crash if moviecart volume control was increased to the maximum
- Brightness control moved in incorrect increments
- OSD display was affected by brightness level
→ NOWSZY [VCS] Gopher 0.28 10/01/2024
Atari 2600 Emulator: Gopher v0.28.0
Changes from v0.27.0
- Paddles
- User input handled more frequently meaning finer paddle control
- Moviecart
- Improved behaviour of video/audio when the movie is rewound to the start/end of the video
- this reflects recent changes in the real Moviecart kernel
- Automatic setting of TV specification now works
- Format of movie cannot be detected until after movie starts
- Television
- Setting the TV mode also changes the underlying clock speed of the console
- PAL and SECAM run at different speeds to NTSC machines
- Added PAM-M
- this sets the clock of the machine to PAL-M but attached to a PAL TV
- Bug fixes
- Stepping back in the debugger
- bugs introduced in v0.26.0
- stepping back by one instruction was out by one colour clock
- STEP BACK SCANLINE and STEP BACK FRAME was broken
- Improved detection of correct starting bank for Atari cartridges
- also affects EF cartridge
- the technique can be expanded to other mappers if required
- Rewind/Fast-Forward icon never appeared on screen
- bug introduced in v0.25.0
- ARM TIM1 enabling was not working
- the enable bit was not being masked correctly
- Capturing of emulation state (for the rewind system) was sometimes missed in playmode
→ NOWSZY [VCS] Gopher 0.27 27/11/2023
Gravitar (Atari, 1983)
Atari 2600 Emulator: Gopher v0.27
Changes from v0.26.2b
- Versioning
- Window title shows the current version number
- executing from the command line with "version" will display the version number
- the
-vflag outputs the git revision- eg
gopher2600 version -v- VERSION command available in the debugger terminal
- Bankswitching
- Implemented UA mapping scheme
- CRT Effects
- Improved bevel effect
- Improved noise implementation, which is now part of the interference effect
- Added flicker effect
- Debugger
- LAST command correctly shows partial disassembly when running in CLOCK quantum
- Added CYCLE quantum
- 6507 Disassembly
- Improved disassembly when decoding previously unseen instructions
- Renderer
- Added simplified renderer targeting OpenGL2.1
- Executable must be compiled to use this alternative renderer
- New renderer does not support CRT effects or screenshots
- Principle reason for addition is to support the Raspberry Pi
- Bug fixes
- Fixed crashes caused when the program window was resized so that it was too small
- this only affected some debugging windows (eg. the disassembly window)

Gopher2600 is an emulator for the Atari 2600 written in the Go language. The accuracy of the emulation is very high and the 6507, TIA and RIOT chips appear to operate without bugs. Certainly, there are no known outstanding issues with any of the emulated chips. It compares favourably with Stella except for speed and final project polish.
