I'm having trouble getting arcade games to play. I'm a bit of a noob so feel free to punch me in the face if I'm posting in the wrong thread.
Basically I have a handful of Retroarch vpks here, several for Final Burn Alpha and a couple for MAME. I've tried all of them and I'm getting really poor results. The CPS1 and 2 emulators seem to run great. I tried Street Fighter II in the former and Super SF2 Turbo in the latter and had no problems. But when trying any of the roms for older games, only one of them (Black Tiger) works. Aliens, Rampage, Mortal Kombat, etc., are all no-go. I've read that FBA for the Vita requires a certain version of the roms (I have no idea how one checks such a thing) and found a website that appears to offer roms in the required version. Still, can't get them to work. The emulator either hangs, freezes, or simply tries to load my rom and then spits me back onto the main menu. It may be worth noting that I downloaded the BIOS for MAME and put all the zipped files in the same directory as the zipped roms.
Is there any one Retroarch emulator that works better than the rest in terms of playing arcade games, at least the ones I just mentioned? Or is it simply too early to expect a good arcade emulator this early? I figure that if a game like SSF2 Turbo works smooth as silk then either I'm doing something wrong or only a handful of games work so far.
