Imago (cocktail set) and M.A.M.E.

0.127u3 [Chris Hardy]
0.71u3 [Pierpaolo Prazzoli]

WIP:
- 0.127u3: Chris Hardy added Imago (cocktail set). Pierpaolo Prazzoli and Tomasz Slanina fixed sprites in Imago. Added Player 2 and removed 2nd coin slot. Changed 'Imago' to clone 'Imago (no cocktail set)'. Renamed (imago) to (imagoa).
- 6th September 2008: Pierpaolo Prazzoli - With another great help from Dox and after 5 years, we understood what was missing to properly emulate sprites in Imago. What the game does is to copy, with an interrupt driven DMA, sprites data to an external videoram that will be accessed when sprites are drawn instead of using the data directly from sprites roms. We still need to check sprites colors with the game PCB and there still are 2 unknown writes executed by game (maybe original bugs?).
- 0.126u5: Added 2nd coin slot.
- 0.100: Aaron Giles fixed palette setup in Imago.
- 0.86u1: Pierpaolo Prazzoli and Chris Hardy hooked up starfield and background tilemap and fixed colours, still problems with the sprites. Added gfx1 rom ($0) and the missing proms ($0, 100, 200). Changed user1 rom ($1000) to gfx4. Fixed rom names.
- 0.71u3: Pierpaolo Prazzoli added Imago (Acom 1983). GFX problems and bad colours due to missing proms.
- 19th July 2003: Pierpaolo Prazzoli added Imago to the Fast Freddie driver.
