TODO:
|
||||
-understand how the blitter really works (commands/video registers etc.);
|
||||
-fix / locate input ports;
|
||||
-understand how the blitter deletes some background parts and understand how the status registers works;
|
||||
-finish input ports;
|
||||
-add the sound chip into MAME (OkiM6376),it's already in AGEMAME so it should be easy to merge it.
