It has a 40MHz AMD 386 and a considerably weaker sound system (dual MSM6295).
TODO:
- Alpha blending. Screen shot on www.system16.com show that during attract mode
in Viper Phase 1 the "Viper" part of the logo (the red part) should be partially
transparent. Same thing with the blu "Viper" logo when on the "push 1 or 2
players button" screen. Note that the red logo is tiles, the blue logo is sprites.
Same thing with the lights on the ground at the beginning of the game. They are
opaque now, you should see the background tiles through.
- Alpha blending on sprites. In Viper Phase 1, see the blue "Viper" logo when on the
"push 1 or 2 players button" screen. Note that the alpha blended red logo on the
title screen is tiles(that effect is emulated), this blue logo is sprites.
