Radica6502 : use palette selection bits in 4bpp mode, format still wrong tho. (#3063)
* radica 6502 tvgames: identify where gfx are coming from in each of the games in the space invaders pack so we can attempt to find the register that controls it, or dma etc.
new NOT WORKING
Tetris (Radica, Arcade Legends TV Game) [Sean Riddle, Incog]
* this seems to be gfx base (nw)
* latest findings (nw)
* trying to work out what these are (nw)
* typo (nw)
* this looks like some kind of dma or sound (nw)
* this seems to be mode select (nw)
* qix isn't so special, m_hackmode no longer needed (nw)
* pretty sure these are the palettes.. format is a mystery tho
* palette select bits in 4bpp mode (taito logo, game selection) palette format is still wrong tho.
* palette/tilemap dma, improves tetris (nw)
