I've created this topic because I've just tried the latest nightly build and it seems we've had some massive improvements over the past few days. Sonic Advance is now FULL SPEED, as is Sonic Advance 3. In other words, mGBA on the Vita is now a viable emulator. I recommend everybody check out the latest nightly. Where can we download the latest nighty? How often is it updated? You can get the latest nightly from here, updated daily at 13:00 UTC. It doesn't specify which version you are downloading however, so just download once daily. https://s3.amazonaws.com/mgba/mGBA-nightly-latest-vita.7z Where should we put our roms? Anywhere you want. Remember that if you put them anywhere in ux0:/pspemu/PSP/, you'll be able to use the same roms with ePSP/VHBL emulators such as gpSP. Super Mario World doesn't work! It just shows a black screen! mGBA doesn't seem to like the cracktro used at the beginning of the US dump by Mode7. Use the EUR release dumped by Cezar instead. Do this also if you have trouble with any roms showing a black screen - the cracktro might be breaking it to try another dump. Do zip roms work? It seems they don't, for now. They crash the emulator. You may save a bit of space by trimming your roms. http://eden.fm/ndstoykotrim/ Can we change the screen size? Or get rid of the border? Use the square button to do this. We don't seem to be able to map 1:1 yet, however. Do we need a bios? No. In fact, although the emulator does support bios loading, it doesn't seem to work. How can we access the configuration menu? Can we load and save states? Use the triangle button. Does this use dynarec? We don't know, although I doubt it because dynarec is not utilised on other formats such as the 3DS. It seems to just be very good emulation!
