@commodore_nerd Well if no linux binary exist then you will need to download the source files from the emulator, compile and make the binary. But first you need to make sure that you have installed all the library packages that the emulator is depending on.
Think of it as needing specific dll files for as specific program/software in Windows to be able to run/execute. (for example directx)
For the Raspberry Pi it will typical be the SDL version of them emulator that you want.
As @mitu described it, is one of the following ways to accomplish it.
@jamesscott go into vice menu and go into speed setting. The first option is warp mode. If you select it, there will be an asterisk "*" on it. Then exit back to game. When you get to the menu screens you can go back an turn it off. Spacebar, return and escape are common buttons used on title screens.
