Title: Cruis'n USA runs too fast
Post by: mrchrister on March 23, 2024, 08:32:04 am
I'm having issues with Groovymame and Cruis'n USA. It runs at around 150% speed on my Groovymame setup.
The game has a resolution of 512x400 at 57.2hz. It is the only game of the 10 or so games I tested that switchres seems to have trouble with. I'm using GM .261 with default install. CPU is 8700k.

I found a fix by disabling modeline_generation in mame.ini but I wonder if other folks have that same issue.

Here is the info I get at command line:
Code: [Select]

Thanks for your reply, but I'm not sure that's the same problem.
1. Regular mame does not have the problem
2. When disabling modeline_generation it works at the correct speed

It seems to be a bug in switchres picking a wrong mode line for the game

Have you tried forcing 512x400@57.349016 Hz 31kHz I'm a swirchres ini override file?

I'll prepare my build and test on next week. I didn't play arcade games for some time :/
