Two little bugs in Scud Race Plus

[Juttar]

I've noticed two bugs in Scud Race Plus (a.k.a. Super Sega GT). After starting the game my controller vibrates the whole time - before I've insert coins. I've used a 360 controller (XInput). Second bug: the prerendered video is a little bit too short. This occures in the new version of Supermodel (221106) but this two problems are older. My system: Windows 10, NVidia graphic, Sega Model 3 UI (20221004).
