Sure, there are a few ROMs that fail in MAME on the Pi, sometimes merely due to performance, but by and large, MAME should be able to launch ROMs from the right ROMset. It should be said here on this thread that getting MAME ROMs to work isn't actually trial and error at all. It may seem daunting at first but give it a go and once you get rolling with it you'll find it a snap to do. As per the forum rules and to avoid any legalities you can't post direct links but the information is available in many locations. Several search engines will produce the results you're looking for. Look under the Emulator & Romset columns for the version of MAME ROMs to match the emulator you're wanting to use. Look here for the ROM set version you're looking for. If you're only looking for a few games you'll find many sites that allow the downloading of single game ROMs for the specific version you need. Yes it would work but you'll see thousands of errors for the missing ROMs but it would work fine with no issues. could i use the method in the tutorial to try and make it work? There are several scenarios where issues may arise but the ROM management tools will organize and do all this for you automatically if you have the correct ROMs before you start processing said in MAME roms not all so lets say I just want one game.

You could also have a correct CRC but named incorrectly. Keeping in mind you'll need to be aware of the CRC on each ROM file as the name could be correct but the CRC incorrect. The only other method I can think of is very time intensive which is to look at the DAT and add them by hand to the proper zip. That doesn't mean every game is working as some are bad dump or no dump ROMs in which case the game just doesn't work for example Xenophobe doesn't work in lr-imame4all or lr-mame2003 but works fine in AdvMAME. The ROM management tools work very well and the DATs guarantee your set will work in the emulator you're building it for. It will also correct the name and verify the CRC. If you have the correct ROMs the DATs will organize them precisely in to the correct zip file regardless of what set type is used like non-merged, merged or split. I don't think it's trial and error as much as following the tutorial. Is there another way to repair the roms so that they can be read correctly? Said in MAME roms not all sorry but this did not work.
