FBA Question: Cannot Find Driver

Libretro Lakka
#1

Sorry again for the noobie questions.

I’m loving this project, and trying to get it all working. I’ve got several Arcade games working but others not working and I’m trying to figure out whats going on. One game, in particular I get this in the logs:

May 21 18:43:03 Lakka retroarch[450]: RetroArch [ERROR] :: rarch_log_libretro :: [libretro ERROR] :: [FBA] Cannot find driver. May 21 18:43:03 Lakka retroarch[450]: RetroArch [ERROR] :: load_content :: Failed to load content.

May 21 18:43:05 Lakka systemd[1]: Started Retroarch.

I’m not sure what driver it is looking for here, and how I install it.

If there is a place to direct me to a primer on MAME/FBA and how to do it, I’d appreciate it. I’m trying to get caught up to speed quickly on how this all works.

That means that the game isn’t supported by FBA. Mortal Kombat and Killer Instinct are good examples.

MAME and FBA are both very picky about which ROMs work with them. For MAME, you’ll need exactly the same romset as the version number of the core. In libretro terms, MAME-2003 is the 078 set, MAME-2010 is 0.139 and regular MAME is up-to-date (161 I think…?). FBA has its own romsets that are closely related to MAME’s and some of them overlap (for example, CPS1/2 ROMs didn’t change for a long time and will usually work wherever, until very recent MAME versions), but it’s most reliable to search for the actual version set.

Both FBA and MAME need a neogeo.zip BIOS to play neogeo games, but it also varies with versions and the FBA one(s) can be hard to find.
