I admit it - I did things out of order -
I installed CRT Emudriver BEFORE I set up Groovy, and now I notice the following mentioned:
Follow Calamity's own installation guides you'll find in the previous link up to the end -- you'll get your system ready for 15-kHz modes and video mode customization as well as Groovy MAME ready for super resolutions, just remember to set the directory of your Groovy MAME's executable file (mame64.exe) and check Export monitor settings to Groovy MAME in VMM's MAME tab.
Is there a way to accomplish this after having already installed CRT Emudriver?
If not, is it possible to uninstall CRT Emudriver and reinstall after Groovy has been set up?
Thanks
