I have been looking everywhere for some concise and direct information on how to get the right roms and the right bios files working for arcade games in retoarch. I have been experimenting with retoarch and MAME core 2014, and I have found some ROMS work just fine without me seeming to do anything. Other roms don’t work at all not matter what I try. It is confusing and frustrating.
I understand that the ROMS I download need to be compatible with my version of MAME, and that the 2014 version of MAME is 0.159. Looking for 0.159 rom sets has proved difficult, however, and many games from emuparadise that are rated for other versions work just fine.
I understand I need bios files to run certain games, but I don’t know which games require which bios files.I also don’t know where exactly to put the bios files. Is it in the system folder, as I did for my other emulators? Is it in the same directory as the rom as is standard for standalone MAME? Neither seems to be working for me.
I don’t know how to verify the integrity of my roms and my bios files. I don’t have a way to trouble shoot what went wrong when my games don’t work.
The most common error I have run into, is the rom loads and nothing happens (black screen), or the rom loads and says something like “Loading (0%)” and never progresses.
