DoDonPachi 2 - troubleshooting missing rom files
« on: February 29, 2020, 04:09:35 PM »
Fellow FBN users,

I am trying to run DoDonPachi 2 Bee Storm. The ddp2.zip rom and a pgm.zip bios that I have run fine under MAME 0.216 but fail to load under FBN RetroArch core. I am getting the following output on the console:


Code: [Select]
[libretro INFO] [FBNEO] Archive: ddp2
[libretro INFO] [FBNEO] Archive: pgm

[libretro INFO] [FBNEO] Using ROM with good CRC and name pgm_p02s.u20 from archive /dane/gry/roms/mame/pgm
[libretro ERROR] [FBNEO] ROM at index 132 with CRC 0xb3cc5c8f is required ...
[libretro ERROR] [FBNEO] Can't launch this game, some files are missing.

Obviously, FBN wants a different a rom and is looking for a file that it can't find. However, having just a CRC of a missing file does not seem too helpful. How do I proceed with troubleshooting this error? Any way to learn the name of a missing rom?

That file in question is ddp3_bios.u37, though I'm not sure why ddp2 wants it.

That's why i provide dat files at libretro's repository, see https://github.com/libretro/FBNeo/tree/master/src/burner/libretro#roms
