I think the OP meant that this emulator includes some overclocking and hacks to make it run 60 FPS in-game. Figured out a solution based on the readme file of that emulator (1964 GEPD Edition), assuming Windows is used. For ROM file, first make sure its extracted and with no spaces in the filename (like "perfectdark.n64"). On the GEPD 1964 emulator, set the ROM directory to be the same as the ROM file. On Windows Desktop, right-click on an empty space, and create a shortcut. Put in the following for the shortcut: <full path to the GEPD 1964 emulator>\1964 -f -g <name of extracted ROM> (Note that the link alone will be enough to open the whole emulator with the game in full screen (due to the "-f").) On Launchbox, add the link as the "ROM" file. Select any emulator as a temporary stand-in. Once the file's added, then click on the ROM in launchbox and press CTRL+E to get into the metadata properties. Then under "Emulation", uncheck the "Use an emulator to play this game" option. Then click "OK" to save and exit. Now doubleclicking the game from Launchbox will load the game from that exact GEPD 1964 emulator at full screen.
