Gaplus (rev. D)

0.62 [Stephane Humbert]

0.35b9 [Manuel Abadia, Ernesto Corvi]

Samples required (Gaplus)


- Easter egg: Enter service mode, keep P1 start and P1 button pressed and move joystick left until sound reaches 19, then (c) 1984 NAMCO will appear on the screen.


- In reverse scrolling stages after challenging stages, the background should scroll at high speed. And when you get the Elephant-head (Blaster-Head that appears at PARSEC 16 first), the background also doesn't scroll at high speed in MAME. Scrolling speed in real board is as same as players speed with Hyper-Head. gaplus36rc2gre Fujix
