A while back I covered Race Drivin’ Panorama, but mentioned that it wasn’t full functional due to the side screens crashing when selecting one of the car types.
It turns out that the cause of this crash was actually a regression affecting ALL the Hard Drivin’ / Race Drivin’ sets in one way or another that had been introduced during a modernization prior to my changes. Osso tracked down his error when addressing the original MameTesters report, and as a result Race Drivin’ Panorama now runs correctly, displaying full-screen views (no car panels) when selecting the Roadster rather than crashing; it turns out the code I wrote before was actually just fine and the game can now be marked as working. --
There are likely other Atari entries to update, but just keeping list brief.
