Description

I made a list of the PCEhawk bugs I'm aware of. For the PCECD stuff, I Tested with both the Redump and Trurip images of the games:


3 Games in 1: Gate of Thunger + Bonk's Adventure + Bonk's Revenge
-Horrible, screechy audio if you choose Gate of Thunder.

Gates Of Thunder (Bugged Audio).zip

Aurora Quest: Otaku no Seiza
-Very poor input response on the title screen. It only works when it wants to.

Burai
-Bad graphic effects on the game's split screen.

BizHawk:
burai bizhawk

Mednafen:

Daimakaimura
-There's a fade out effect on the ending sequence, but it doesn't fade out correctly, causing graphic glitches to occur.

Final Blaster
-Wrong graphic positions on the game's intro. It's hard to do comparison pics or explain, but basically, the horizontal sequence of images should first appear on the middle of the screen, then the top, then bottom. On bizhawk they all appear on the top.

Popful Mail
-Garbage graphics at the game's intro. Maybe more corrupted graphics later on.

Star Breaker
-Game crashes upon leaving the first town.

Star Breaker (Japan) (Save State).zip

Steam Heart's
-Black screen only during stages. Not possible to play the game.

Takeda Shingen
-Game stops responding to inputs when swords are locked, making it impossible to continue unless if you reset it.

Valis
-Black screen only through the entire game. Impossible to play it.
(still needs CD access time emulation)


The main problem is that the creator of pcehawk (Vecna) is no longer around to fix the above issues, meaning they'll likely never get fixed. Since none of those bugs exist in the latest mednafen pce core, I'd like to suggest waterboxing it as the primary core for pce TASing, while still leaving pcehawk as an option. The pce emulation from mednafen is certainly better overall, and more mature than bizhawk's.

Research direction

No files, tests, or entry points are identified. Start by confirming which PCEHawk and Mednafen core components handle the listed games and determine whether each problem is a separate bug; done would require a scoped fix or a decided core-migration plan with tests or reproduction results for the affected games.
