Frame Buffer: MODE is unsupported for 128-135 #132

Closed mincebert closed 3 years ago

Trying to switch to MODEs 128-135 gives an 'Unsupported screen mode!' error.

Obviously, these are the shadow modes on the B+ / Master and it would seem more helpful to make them select MODEs 0-7 (especially as a shadow mode doesn't support direct memory access).

This breaks a lot of Master software on the Welcome disc (maybe some other things that aren't implemented, too!).

Thanks for the bug report.

I'll definitely fix this one!
