When loading N64 games there is no video, audio is working but you only see flashes of solid colors. I am using RetroArch 1.0.0.2-r34 and I have attempted using versions 1.0.0.1 and 1.0.0.0. I tried using .z64 and .v64 to see if it was an issue with endianness. I also checked all of the graphics cores and tried loading multiple ROMs but video did not work with any configuration.
Same happens to me as well. I do have the n64oid.apk from a few years ago and interesting enough that seems to work. I only tried firing up Majora’s mask and was able to get to the screen you input your name. I was in a hurry though so just shut down at that point. I have no clue how similar the two emulators are but hopefully it is a minor thing.
