I try to load both Sega Genesis and Sega CD roms and neither work. In the case of the Genesis roms, when I click to load it briefly pops up the "playing" popup in the upper right hand corner then it just goes away as if nothing was pressed, almost as if the file doesn't exist. It doesn't ever leave the Kodi environment. It does not popup the emulator choice screen or anything.
As an interesting side note, it does not seem to have a addon folder for the pico or gen emulators in .kodi/.../addon_data/ but it does have folders for the NES and SNES.
I have the BIOS files needed and they are named correctly (case also) but perhaps they are not in the right place?
