Does anyone has the same problem?
Only some of my Neo Geo Zip files are working. Metal Slug 1 + 2 is okay, but Metal Slug 3 + x +4 don't work.
If i use the FBA converted files, they work. Same problem with Prehistoric Isle 2, *.fba works, *.zip doesn't work.
neogeo.zip bios is already in the game folder.
