Cruis'n USA runs too fast
« 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]
c:\arcade\mame>groovymame.exe crusnusa
