After two years of waiting in the closet, finally I found out some time to take out my bppc bvision stuff and setup on a backup mobo. After about three days of struggling with rom updates / patches / boing bag mayhem, I managed to setup a stable system (I hope) however, I still can't run the planet potion demo, which was my main goal setting this up in the first place. I've installed both boing bags, do a bppcfix, installed cybgraphx 3 with bvision support with some extra libraries as described here (http://www.amiga.org/forums/showthread.php?t=15304) by patrik (thanks !), installed the warp up update from here (http://phase5.a1k.org/index.php?id=0) and the warp up3d and can view all the warpup3d demos without any problems. Oh, and I skip the exec.library rom update as described here (http://www.gregdonner.org/os39faq/compatibility.html#16) cause it prevented me from selecting bvision screenmodes. I'm running a 1172 something screenmode. Do I need to be in a specific screenmode to run the demo ? any help or tips appreciated ...
thanks !

I never managed to run Planet Potion on my A1200. It just crashed and also many others had troubles running it on A1200. I guess demo is not very compatible.

It ran fine on my BPPC/040 with the sole exception of sound. The sound would always get choppy when there was a lot of stuff going on and no amount of messing around with stuff ever helped that.
You should drop your workbench screenmode to some low resolution, 640x480, for example, before starting the demo and make sure you don't have any other BVision screens open. The reason for this is that the RTG system doesn't seem to handle paging very well.
Rather than the workbench screen getting paged into fast ram and you getting all that VRAM for your demo (which it needs for framebuffers, z-buffers and texture data), you seem to get whatever unfragmented dregs are left after your screens have taken the lion share.

WHOOOOOA BABY ! Finally I managed to get this working and WOW ! It was really worth all the hassle ! :devildance: :pint:
The bppcfix (ver 1.2) I got was buggy, it didn't remove the resident 68060.lib . But I found a newer (1.4) version from here (http://devnull.owl.de/~frank/ppcemu_e.html) which works ok, which solved my problem !
and, I needed to load 68060.lib from disk immediately after bppcfix at startup. It doesn't do it automaticaly and the system hangs ... get loadppclib here (http://aminet.net/util/boot/loadppclib.lha) (load060lib and load040lib included)
Also, I got to get AHI installed, it's not mentioned anywhere but all ppc demos seem to require it. It's available at aminet with all the drivers (I just run on paula).
Yes, sound was a bit choppy at times, but not a big problem. Also, a requester pops up before running which says you should enable echo and DSP. Probably a DSP enabled sound device is necessary for smooth sound.
