I did that. I had to manually install it. For some reason zipped or unzipped, Launchbox won't see the app file. If I do it manually it does though. Same thing happened with Dolphin. Launchbox wouldn't see the .exe files when I selected the Launchbox prestored emulators like snes9x, Dolphin, etc. Some emulators, like 4DO, cemu and nestopia loaded fine using the prestored Launchbox emulator name.
I can't explain it, but the bottom line is that all the emulators are now loaded.
Thanks for responding so quick.
