I was testing retroarch with an old game i have, “Resident Evil Gaiden” for GBC, and i ended playing it entirely. But near the end, i found an issue with the game, and i found a reference to it on internet, but not anymore information or if it’s a ROM issue, or the emulator.
When you are almost in the end of the game, you can fight with a upgraded version of recurrent boss (Mutated B.O.W.), but when you are in the fight, and it moves back, the image began to glitch and then the game crash. I recorded it to show exactly what happens https://youtu.be/PEDy0-QAzac .
Used RetroArch (1.9.0, Linux) and Core Gambatte (v0.5.0-netlink) to play the entirely game. Also tested with SRM save and save state in cores Sameboy (1.8.4 35ee9ab) and mGBA (0.8.3 b485ee7), all with the same issue. The ROM i used is “Resident Evil Gaiden (Europe) (En,Fr,De,Es,It).gbc” (MD5: 8a7f483857e251d56a16594ca84d1a7e), also know as “Resident Evil Gaiden (E) (M5) [C][!].gbc”, allegedly reported as a Good Dump. Played in Spanish. Also tested with copied played ROM SRM save with “regaiden.gbc” (cf4d77137f7dd485480d83e33fe76879) with same result, which is a known finishable version https://youtu.be/kiYyjGjlPKo?t=1086 [18:06] but with different setup (VBA-M r1228, No RetroArch).
Searching for answers, i found in the comments section of this site https://retroachievements.org/game/5133 a reference of this is an known issue with the game, but this is the only reference of it i found, but also i see videos of people playing this part without the issue.
Is this really a known problem with this game? Is a dump issue? (Where can i search for know good dump hashes?) Or is it an emulator issue? How can i help to debug this?
I can provide the save files if this can be useful.
