@zing said in Some games not working since latest release:

You need to check the ROMSET of your ROMS: on all Arcade consoles, it is necessary that the ROM version corresponds to the core version, for example, the MAME2003 core will be used with MAME2003 roms, you can even work with MAME2010 ROMs and vice versa, but not in the right way.

I'm not sure which Bomberman the OP is talking about, but "Bubble Bobble Featuring Rainbow Island" is definitely a psx game.
@Blythy79 If the Bomberman is also PSX, then my guess would be improper device settings, i already mentioned it in other topics : you need a proper "device type" value set in Quick menu > Controls > Port X Controls, and you need to set the proper multitap setting in Quick menu > Options depending on the game, meaning disabling multitap for games not compatible with it, or enabling it on the right port for compatible games.
