More important: those with knowledge of these things should contribute to the Wiki so the RetroPie community needs it and can certainly benefit from it. I will try to compile common questions and answers tonight as a start. Just copy the entire thing over to /home/pi/RetroPie/BIOS/mame2003/samples/ĮDIT 3: It just dawned on me that a FAQ and TIPS sections on the GitHub Wiki MAME section would probably be really helpful. and make sure you keep these together.ĮDIT 2: About the mysterious "samples" directory, thx /u/wotan: There's a folder called samples in the romset that contains sound files for games. with added game support plus many fixes and improvements - GitHub - libretro/mame2003-plus-libretro: Updated 2018 version of MAME (0.78) for libretro. all you need to do is to put this ZIP format in Mame Roms directory. (2) Copy samples and BIOS into proper directories, then if filesnames have similar names such as game1a.zip, game1b.zip, etc. Updated 2018 version of MAME (0.78) for libretro.
(1) To save yourself the headache of wondering whether you have the right files, try downloading the full romsets and throw those in the arcade directory.
TL DR After struggling for weeks to get MAME ROMs to load correctly I finally stumbled upon a no bs answer here on Reddit and finally got my ROMs to work, which inspired me to update the official GitHub Wiki.ĮDIT: Some simple, and great advice from comments below. I modified the table to remove the useless "BIOS extension" column where each entry was ".zip" and added a paragraph with an example showing exactly what you need to do to get a MAME ROM working (along with a few other improvements). So, I updated the Wiki with some information that I think will really help others and would have helped me when I was struggling. Why didn't the main GitHub Wiki have a simple example like this? It could have helped so many others that came before me. I was finally able to get Metal Slug working! Finally! FINALLY!!! Reboot Emulation Station and the roms will appear. Just copy them all if you're not sure what does what, doesn't take up a ton of space.
Attention: my new romset updated to the revision now it is compressed in the Split method, no longer in the Non-Merged method.
Copy the bios files in the romset over to the /home/pi/RetroPie/BIOS/mame2003 folder. Download and install the MAME 2003 PLUS LibRetro core on RetroPie/RecalBox/RetroArch and configure the path of the roms folder.Copy the roms you want over to the mame-libretro folder.For more details use the link to the post. It's one of the most confusing parts of RetroPie.įinally I came across this helpful Reddit post that had a no bullshit answer and actual instructions of what to do and where to place the files.ĮDIT: Here it is summarized below. It seemed like every time someone tried to explain it on a forum or blog post I left feeling more confused or discouraged, so I put it off. Like many other poor souls not privy to MAME ROMs and emulators I struggled to get my ROMs to work.
