Heretic 2 needs at least 64MB memory just to get out of bed. I wouldn't reccomend it for any system with less than 96MB *directly on the accelerator card*. Motherboard memory is just no good, especially on the A4K.
Try something smaller first:
1) Download the warp3d 4.2 archives and find the Gears demos (there are 680x0 and PPC versions).
2) Choose an 800x600 16-bit workbench screenmode.
3) Run the windowed 680x0 version of gears. Does it work? If not, your warp3d installation may need looking at. You may also have problems with your RTG configuration that affect warp3d. For instance, under CGX you must have the "bitmap cache" option enabled, as well as anything else mentioned in the documentation.
4) If the 680x0 version runs, try the ppc windowed version. If it does not run, your warpos settings may be arwy.
If nothing works, there is also the possibility your firmware on the PPC card is the problem. In my experience, the grexx-enabling versions of the flash totally kill off warp3D on the BVisionPPC/CVisionPPC and may affect other systems as well. Only use them if you have a G-Rexx, otherwise avoid.
-edit-
Hmm, somehow I got the impression you have a CVisionPPC, but I must have been mistaken. You don't say that anywhere :lol:
