I was able to reproduce your do_handle_screen_fault error.

This error on Basilisk II has been discussed before a couple of years ago, using older source code as the Maemo port uses. The developer (Gwenole) fixed it in later source code, but I don't know what he did.

I just compiled a port for OS 2008 using a Basilisk II (JIT) source code tarball where the bug was fixed and it doesn't have the problem. But it's slower, the screen size is limited to standard resolutions, and it can't switch to full screen.

I'll be messing around with t3h's hacked code and the dozens of source code releases for Basilisk II and Basilisk II JIT I have on hand in Scratchbox. I just uploaded them if anyone knows what they're doing.
