[VCS] Gopher 0.25.0 13/09/2023

[2] @ !!! Czwartek, 14 Września 2023 21:47 CET [14-09-2023 21:20 CET]

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.

Commando (1988, Activision)

Changes from v0.24.2

 ARM

  •  improved ARM disassembly, particularly for Thumb-2 instructions
  •  implementation of FPU and instructions
  •  registers window in debugger
  •  COPROC STEP command forward by single ARM instruction
    •  useful in conjunction with source window, local/globals window and/or registers window
    •  preparatory work for ARM level quantum control

 ELF

  •  "byte streaming" of ROM data - leading to significant performance improvement
  •  initialisation sections executed before main() function
  •  Notifications
  •  notification icon for coprocessor development files
  •  transparency setting
  •  fixed conditions under which combinations of notifications are shown

 Bug Fixes

  •  fixed bad image stutter when refresh rate is inconsistent
  •  crash in timeline window when scrubbing past end of rewind history
  •  thumbnailing no longer causes the application to hang if the ARM emulation crashes
  •  FPS measurement was broken if television was being nudged
  •  "fastload" supercharger ROMs (ie. bin files) would crash debugger

 Known Outstanding Bugs

  •  rewinding of ELF ROMs when byte streaming is active sometimes produces a  skewed image

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

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

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
