Display test items (in order):

- display attribute
- character set
- 80x25 display (pitch opcode)
(With the above ends the things that works with current core, urgh)
- graphic test, lower rasters (FIGD opcode)
- graphic test, upper rasters (FIGD opcode)
- zoom test 1 (ZOOM opcode)
- zoom test 2 (ZOOM port)
- DMA Display Write test (DMAW opcode)
- DMA Display Read test (DMAR opcode)
- Display Random Data (Tests VRAM I suppose ... for whatever reason at this point emulation crawls a lot there)

In the end, I have to implement the color banking to both the driver and the GDC core too, this is because most tests have a color version too!
