Is this group still alive ?

I'm trying to run FantaVision, unsuccesfully. I've tried gplus,gsport, both ROM 1 & 3, and a couple different FantaVision versions. The online version has the mouse as described, it erases the background. But on my PC, there's no mouse at all! I would actually be fine with an erasing mouse, but I need to be able to save a FantaVision movie file as I want to reverse engineer the format. (Can I save a local file from the online emulator version ?)

Thank you
Sigurd

Fantavision hangs when it starts on KEGS-based emulators (which includes
GSport and GSplus) due to a bug in the way KEGS handles the WAI instruction.
Fantavision masks interrupts with SEI, sets a SHR line interrupt, and then
does a WAI instruction. This hangs KEGS since it expects an actual interrupt
to end the WAI, but there won't be one since interrupts are masked. I never
realized this was a valid WAI use case.

The fix is easy. In instable.h, change:

instcb_SYM /* WAI */
g_wait_pending = 1;
CYCLES_FINISH

(There may be some stale #ifdef ASM code, just ignore that) to:

instcb_SYM /* WAI */
if(g_irq_pending) {
g_wait_pending = 0;
INC_KPC_1;
} else {
g_wait_pending = 1;
}

Thank you, but this is the file format for the Amiga version of FantaVision, unless I'm missing something I haven't found the file format for the Apple 2gs version

Yes. Good luck with your FantaVision project and keep us all informed...

Thanks Kent,

I was able to fix this in GSplus and will make sure it gets in the next release.

Best,
Dagen
