0.35b10 [Keith Wilkins, Phil Stroffolino]


- Sprite/tilemap orthogonality needed

- Bad road colors in Final Lap and Suzuka series

- Finest Hour: ROZ plane colors are bad in-game

- Final Lap: Sprite size bit is bogus during splash screen

- Final Lap 3: Bad steering and uses unaligned 32x32 sprites, which aren't handled correctly in video/namcos2.c yet

- Four Trax: Some graphics glitches (POSIRQ-related?) and sprite banking (for rear view mirror) isn't working

- Suzuka 8 Hours II: Some sprite cropping issues

- Legend of Valkyrie: Gives ADSMISS error on startup

- Bubble Trouble (Golly Ghost II): Not dumped


- How to calibrate the guns: hold 9, press f2 and shoot at the targets it shows using the crosshair, after you've shot the target press 9 again to move onto the next one. Once you get back to the start again press f2 to exit.


- Hardware: The Namco System II board is a 5 ( only 4 are emulated ) CPU system. The complete system consists of two boards: CPU + GRAPHICS. It contains a large number of custom ASICs to perform graphics operations, there is no documentation available for these parts. The system is extremely powerful and flexible. A standard CPU board is coupled with a number of different graphics boards to produce a system.

- Final Lap 1-4 cabinets may be wired together. To move through self test options, press gas pedal and change gear shift from low to high. To change an option, move gear shift from low to high without touching the gas pedal.
