- conio library functions work; - contiki crashes :(

Doesn’t fully work, but is the only OS of any sort available for the TurboGrafx-16/PC Engine. Since the TurboExpress is highly compatible with the TurboGrafx, it can be assumed this will work.

Whether these emulators support operating systems for these computers is unknown; it must be looked into further. PCs without meaningful OSes are not included.
