x68000 Game Settings

In the wild west of x68000 game development, there doesn’t seem to be much in the way of standards across games. This can include switching to 31Khz or turning on MIDI audio or different controls. Luckily someone before me has gone through and documented much of this very important information, so important that it would be a shame for it to disappear one day. This page serves the purpose of a backup, and an extension of this information.
