San Francisco Rush Freezing?

[TrainwreckX]

I was wondering if anyone with a copy of San Francisco Rush 2049 could help test something for me. I have had this game completely lock up on me if I leave it in "attract mode" at the title screen for about 10 minutes. It's done it to me half a dozen times, always on this screen, and I'm wondering if something is wrong with my copy of the game or if this is just potentially a bug that slipped through on that title. Midway classically had manufacturing issues with their games, so it's worth checking.

For what it's worth I'm also having a random freeze on Hydro Thunder even though I definitely have the "Hot! New!" version. These are the only two games that seem to be giving me an issue. I left Power Stone running in attract mode for an hour without it crashing. By the way, there is a stone "WHICH HAS THE POWER TO MAKE DREAMS COME TRUE!"

I left my legit US disc of 2049 on the title screen for 15 minutes and nothing happened.

Thanks for testing it. After a thorough cleaning of my Dreamcast (including the inside), it's still happening but ONLY on this game. I've tried leaving other games running on the attract screen for a long time (Power Stone for 30 minutes as example). Nothing. But Rush still freezes. So I thought it was my disc maybe. But it looks great and doesn't have a lot of scratches.
