In summary:
- mbee 256TC is using 4 bit colour
- mbee 128K is using 5 bit colour
- mbee Premium Plus isn't setting colours.
Why isn't the premium plus colours being set? Is it using some other method to access the colour table?
Should I use the 256TC or 128K colours?
How do I set the 256TC to 64 column mode?
I've never used Mame, so I can't comment on the Premium Plus implementation properly, but it should be just the same as the 256TC output.
Same Screen / colour / PCG arrangement. The Premium Series and 256TC are the same in this regard and programmed exactly the same.
The Premium Plus is a regular Premium Baseboard (where all the screen stuff is) with a new coreboard ( to do mainly the SDcard Floppy emulation).
I don't know why someone (not referring to our member 'someone') would create a mame emulation specific to the Premium Plus unless they
are going to emulate the Coldfire second processor as well - without that, it's a regular Premium Series machine.
The screen shot of the Premium Plus output seems to be the Boot menu screen colour positioning, with garbage / unwritten screen ram contents.
