There are still a few games (like Street Fighter 3 for example), where I pulled the rom from the 2010 set + used the 2010 core on Retroarch, that still crash back to the main menu. One thing did leave me scratching my head. And it has virtually everything I was missing! After installing that core from the experimental packages, I'm much further along now and ready to just call it good. However, after poking around on the internet archive and a few other safe sites, I did find a working set of MAME 2010. Yeah, but I always was a little leary of downloading things outside an established community who are typically more careful with what they upload (as to avoid virus and other malicious things that can infect you). obviously search for the complete set and not individual roms.

i can't give any advice but i would struggle to figure out to google for something related to that list that wouldn't turn them up to be honest. You can, but yeah, it's a bad idea because of the above said in How to Fill in the Gaps of Mame the ones in the recommended list are very easy to find, seriously. If I get it working on some of these missing roms, can I use it as my default across the board (providing I match up the rest of the sets)? Or would that drop my performance overall? I like the idea of having all my games under one core, but if that might hurt performance in other areas, I'll do different ones for different games if I must. If I remember correctly, it's under the optional or perhaps even the experimental packages. there are certain games that will only be viable on the later cores, and are still playable, but you'll have to experiment to find out what those are, but i would always recommend the. later mame versions have more sophisticated emulation which means the games that they have in common with the earlier cores will only ever run slower, and the newly supported games will likely be far too slow anyway. like say, the recommended cores are chosen because of good performance and because they're mature, feature-rich libretro cores.

For example, does lr-mame2016 perform as well as say the default core? One quick question on the alternative mame cores. With the hopes that later hardware upgrades or Pi versions might make them playable. Sounds like I should be able to at least get them to load if I match the right set+core.
