Rolling Thunder (new version)

0.35b1 [Jimmy Hamm, Phil Stroffolino, Ernesto Corvi]


- In the arcade you could crouch and then switch directions while crouching without standing back up. It uses 4-way joysticks. And you can easily turn and shoot while crouching in MAME. You just have to be shooting while you turn and shoot, just like in the arcade. Stroff

- About Rolling Thunder door glitch: Spriteram buffering fixes sprite lag, but causes a glitch in rthunder when entering a door. The *closed* door is made of tiles, but the *moving* door is made of sprites. Since sprites are delayed by 1 frame, when you enter a door there is one frame where neither the tile-based closed door nor the sprite-based moving door is shown, so it flickers. Given the experience with Baraduke, where a glitch like this is apparent in the floor 6 boss, this could very well be a bug in the original; if it isn't, I wouldn't know how to fix it. In the source code, there's a comment as left, it happens on the pcb too as well as the ugly refresh when a screen is changed. Kold666 (rthunder0104u3ora)
