i am using a ds lite, i have a 2016 r4isdch gold pro card. I put the newest jenesis on the root of my sd card. but,, when I open the folder where all my genesis roms are, the emulator doesn't see them. I don't know if I have to patch them or not, but im guessing I probly do. the roms are in .md format. I don't get it, the roms work on my smartphone emulator just fine lol also, I don't have a pc to patch roms, but I have my phone, I have the app -rom patcher- found in the playstore. also,, just to let you know, I have never patched roms before lol but I can figure it out.
