[VCS] Gopher 0.28 10/01/2024

[1] @ środa, 10 Stycznia 2024 23:59CET

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 posiadający dość dobry filtr "psujący" obraz i parę dodatkowych ustawień pozwalających na dopicowanie naszego wirtualnego VCS.

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

Atari 2600 Emulator: Gopher v0.35.2 23/11/2024

Changes since v0.35.1

  • Added cartridge mapper
  • FA2
  • 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:2
      • Some 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)

    •  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
