RTG Games - black screen - A1200 - Vampire V2 - Coffin OS

[neodeus]

Hello Everyone,

I was just wondering if anyone here had any ideas. I have an A1200 with a Vampire V2. It has the 2.17 core installed. I downloaded the latest coffin OS image and wrote it to an SD card. I have an SD to ide adapter plugged in to the Vampire's IDE. Coffin OS loads fine. RTG in coffin OS is fine through HDMI. One problem I have had for awhile, however, is a lot of the pre-packaged RTG games do not load. I tried ZDoom, Quake, Shadow Warrior, etc. The games seem to launch, but then I get no signal on my monitor. The screen just remains black. I had Coffin OS on the card for a bit, so I thought maybe it was something I had messed up early on when I first started messing around with it, so I reimaged the SD card with a fresh install of Coffin OS. Trying the RTG games again the screen is still just black. Can anyone think of what might be wrong?

Thanks!

It sounds like your monitor might not support the resolution the software is running at, do any of the applications let you pick the screen modes? Try something like 640x480/800x600 these are often quite safe, some newer screens don't like old modes like 320x240 which some Amiga RTG software might be using, they also might be actually going to a native screen in which case you need to output to another monitor unless you have a switching solution
