This is a new PC build and my testing shows that the display is working but with a lot less than the 160 modes suggested - more like 20.
Not sure which step I'm missing. I did the following:
1. Installed ATI card driver from the crt_emudriver package.
2. Unzipped CRT_Emudriver
3. Edited VMMAKER.INI and specified MameExe location. Changed Monitortype from "CUSTOM" to "GENERIC"
Ran C:\VMMAKER\VMMAKER.EXE.
Rebooted.
I mostly followed the instructions
here, which worked very well.
You can see from the attached screenshot of the available modes that most of them are different frequencies of 640x480.
Should I be getting any more modes with that hardware combo? Do I need any more? I'm using groovymame, which games should I test?
