Thanks number6.
I just remembered that I get a small window that says "Unable to open display" when I try to launch Brilliance or True Brilliance from OS4. If I recall correctly they default to 320 x 200 screen when I use E-UAE. I don't have this choice available in my normal OS4 screenmodes.
I'm running it without E-UAE of course.
I could give you a step-by-step using ModePro, but even with the blitter emulator, it is just more of a curiosity to see it running, due the issues.
Oh, and it's possible you're hung up actually on the Brilliance warning screen. If you recall running under OS3.x, you get a requestor regarding whether SetPatchMrgCop is installed or not. If you can't get passed that you have no shot of starting the program on NG.
