Fake86 (68k SDL Port) - 8086 PC emulator

NovaCoder · 05 December 2014, 04:20

A portable, open-source (GPLv2) 8086 PC emulator.

Fake86 is an 8086 PC emulator written in C. It is written from scratch, including the CPU core and has been under development since October 2010. It was originally written in FreeBASIC, however I have since re-written it in C for greater speed and portability.

Execution terminated

Compilation successful

Buggered if I know if it runs, haven't even tried it myself yet

The timings are probably way off and the threading might be completely wrong (I was drinking Vietnamese beer at lunchtime).

It would need an 040 + FPU and PAL AGA + lots of STACK

And you'll need to copy all the files it needs (eg videorom.bin) to RAM:

This is based on v0.12.9.19

Update: Just gave it a quick go, seems to run out of memory during audio start up?

Updates: Running with -nosound gets it past the memory crash but I also get a black screen same as Arti.
After actually looking at the code properly I can see that it's using 32 bit color values which wouldn't really help much

Cool, good luck with this!! Is it a bit too early to ask what the potentials are with this?

turrican3 · 06 December 2014, 14:40

Happy to see you on a new project nova !!!
You never sleep ??

NovaCoder · 11 December 2014, 06:04

I don't sleep enough, I know that much

I replaced the threading with the SDL equivalents and compiled against the 'old' RTG SDL.

This produced and exe that runs but it doesn't get very far (just seems to get stuck in a loop). I suspect the problem is down to endian issues (yet again!)

I'll try and recompile it against my updated RTG SDL with debugging enabled and see what it's doing.

I've also been in contact with the Author of Fake86 who's keen to see an Amiga Classic port of his emulator so he might help out with an 8 bit update.
