So, I have a few followup questions and some new ones if you don't mind using your fountain of knowledge.
1. What do I need to do with that Virtual Box file. It is exe not xex. Just to inform you though as it may help. I have no PC. All I have is an Android and my RGH 360. What about this:

2. When talking about BIOS I was right when saying about built-in games. There are [BIOS] and then there are the BIOS you mentioned. I saw on RetroArch that it says some of them are missing and required. I tried some from the roms link but I didn't really know what to do from there. I did try putting them in the roms folder and launched one. It took me to the dashboard (MegaCD), but that was it. Stuck from there. Or do I put them in a specific place as it still said they were missing.
3. Doom crashes my console. Ideas? It just goes black and freezes. It's the prboom that was included. I "may" have moved the folder and caused a problem.
4. I tried the Snes360 emulator but found it ran Mario Kart at a faster speed. I only noticed it on that game. Is there a speed setting do you know. After finding out that I was using an older RetroArch and downloading your newer version I will be using that for most roms now, so thanks. I only really want to use this emulator now for the achievements. Which is a nice addition I thought.
5. Linked to above, other than the Genesis Plus emulator, are there any others with achievements?
6. On the RetroArch site it says there are other emulator extentions. Do you know of any I can add? 32X and Jaguar. I couldn't find an Atari 2600 one. Shame. I do have the Virtual Jaguar, but it seemed to crash even without trying a game.
7. MAME. Now the version on here seems to says .72 I think. The roms I found seemed to all be higher. I'm very confused with MAME.
That's it for emulator questions. For now.
