-Sega GP World hardware
-Driver by Andrew Gardner with help from Daphne Source.
-
-Notes:
- - GP World is a rare game that came in a huge cabinet with two monitors, side by side.
- The image from the laserdisc was stretched to an 8x3 aspect and graphics were overlayed
- on top.
- - The hardware is similar to Astron Belt but somewhat more powerful.
-
-
-ToDo:
- - Hook up start lamp to mame lamp system
- - Do the gear shifter right
- - What's up with the pedals being tied together?
- - Daphne says this game is dual monitor. Is it?
- - Finish sprite drawing - looks awfully similar to system1 and suprloco.
- - Palette!
- - Still some undocumented reads and writes - likely dealing with I/O.
- - Convert to tilemaps.
