BigPEmu v1.19

Atari Jaguar模擬器 BigPEmu 發布新版，更新如下 :

- Added some more unaligned read/write edge case handling. This addresses a problem in Theme Park, possibly among other things

- Changed some undocumented RISC instruction behavior to match some of my local hardware tests. One of these changes is known to correct an issue with object directions in Defender 2000

- Added more Jaguar GD functionality. Filesystem functions are stubbed out, but I wasn't sure if anyone really needs/wants this fully implemented, so let me know if it's important to you

- Fixed a few "undefined" Blitter cases (not known to affect any existing titles)

- Linux ARM64 builds are now part of the automated build set. Special thanks to cubanismo for guiding me through the minefield of cross-compiling for ancient Linux targets

- Significant improvements to the network rollback functionality, propagated back from BigInstinct

- All kinds of new platform/framework functionality, also propagated back from BigInstinct. I didn't feel like going through hundreds of changes to make a coherent summary, but one of the more notable additions is a byuu-style run-ahead option

- Exposed a bunch of sound spatialization functionality to the scripting API

- Exposed MOD and MP3 playback to the scripting API

- Added a timing fix for Val d'Isere Skiing and Snowboarding

- Various developer build changes to more accurately reflect hardware and/or detect errors which would break on non-developer builds (this includes enabling M68K address exceptions)

- Lots of "anti-emulator" code will be failing in developer builds at this point, and some related functionality may be propagating to non-developer builds soon; relying on inaccuracies to prevent your software from running in BigPEmu is unwise. If you really want to prevent your software from running in BigPEmu, contact me about better/future-proof methods

JoyToKey v7.1.1

 鍵盤 <--->手把映射軟體 JoyToKey 發布新版，更新如下 :

• Improved the key code emulation for Pause/Break key, and also provided the alternative key code (accessible from the right-click menu).
• When the button assignment changes due to SHIFT function or active profile switch, there has been a feature to ignore the already pressed input "for the specified time". This feature was enhanced to be also able to ignore the input "until it's pressed again".
• Added "Tab" key in the right-click assignment menu.
• Bug fix: When the same button's definition is triggered from multiple buttons, (e.g. Button[20] is called from both LT and RT), it wasn't released at the expected timing.
• Bug fix: Fixed the occasional display issue when "Options" tab was selected.

Known issues

Several games exhibit graphics or sound glitches. See Issues for details. Specific cases:

• After Burner II: some sprites that should be transparent are rendered in a black box
• Akumajou Dracula X: sound effects sometimes play too quietly or are silent
• Die Hard Arcade/Dynamite Deka: missing sound effects
• Doom: minor graphics artifacts. Sound effects only play on the left channel when using Stereo audio (#192)
• Fighters Megamix: some graphics are slightly offset to the left (#190)
• I Love Donald Duck: sprites persist through some screens
• I Love Mickey Mouse: status bar and other HUD elements are missing
• Final Fight Revenge: the ground is just a plain color (#104)
• Groove on Fight: character sprites are glitched (#70)
• Marvel Super Heroes vs. Street Fighter: flashing graphics
• NiGHTS into Dreams: doesn't play the intro video (#46). You can skip it by pressing start on the black screen
• Phantasy Star Collection:
  • Phantasy Star I: audio is quiet and only plays during the intro
  • Phantasy Star II and III: audio is played on the right channel only
  • Phantasy Star IV: goes to a black screen and only plays music
• Sonic Jam:
  • Main menu text sometimes isn't rendered (#131)
  • The status bar at the top of the screen in Sonic World is partially drawn (#131)
  • Music stops playing after a while (#83)
• Sonic R: some sound effects (like the pause jingle) play back incorrectly
• Virtua Fighter: glitchy in-game graphics (#40)
• Thunder Force Gold Pack 2: no audio in either game (#145)
• X-Men vs. Street Fighter: flashing graphics

Netlink-capable games are not supported yet; these either boot back to system menu or hang on the SEGA logo:

• Daytona USA CCE Netlink Edition
• Daytona USA Circuit Edition (Japan)
• Duke Nukem 3D (USA) (#136)
• Saturn Bomberman (#63)

The following games softlock or freeze during gameplay:

• Advanced V.G.: freezes when selecting a character
• Assault Suit Leynos 2: freezes on a black screen in-game
• Clockwork Knight 2: freezes on a black screen when starting the game
• Grandia: freezes if VDP threading is enabled. The 3D graphics glitch out if VDP threading is disabled. (#91)
• Sakura Taisen: freezes during certain dialogue lines (#90). Can be worked around by mashing B to skip sound clips before the softlock happens
• Sakura Taisen 2: freezes during certain dialogue lines
• Vampire Hunter: freezes if you let the intro sequence play past the "Vampire" logo

The following games stay stuck on the SEGA copyright screen, on a black screen or boot back to the system menu:

• Astal (#132)
• Capcom Generation - Dai-5-shuu Kakutouka-tachi (#68)
• Crusader - No Remorse (#108)
• Discworld
• Jung Rhythm (#85)
• The King of Fighters '95 (#75)
• Mega Man X3

Miscellaneous issues:

• Switching discs or returning to the system menu with A+B+C+Start while using a Japanese IPL (BIOS) ROM may cause the system to display the "Game disc unsuitable for this system" or "Cartridge unsuitable for this system" messages. As a workaround, force a hard reset (Ctrl+R by default) to fix this.
• Rayman: inputs are inconsistent (feels like pushing a turbo/repeat button) (#59) and has some graphics issues

This game currently only works with SH-2 cache emulation enabled:

• Dark Savior (#134)
