Which core for MAME 0.184 ROMS?

Hi everyone,

I’m quite new to things like gameshell and how they work. I have a stack of MAME 0.184 ROMS that I’d like to play on my gameshell, but for the life of me I can’t figure out which core I need to use for them.

When I loses the first ROM in to test (metal slug X) gameshell asked me if I wanted to auto set up, and I said yes, but the game never loads, I get booted back to the main menu… any tips on what I’m doing wrong?

the MAME emulator that comes on the SD card takes runs with v0.78 ROMS. You may need to rebuild your ROM set to the earlier version, or refer to here:
