This is a 255 byte demo from Digimind. I think it doesn't work because the demo expects the registers to have certain values at program startup. I don't think DOSbox would oversee such a big issue though.
It can be downloaded at:
Dunno but all regs should match msdos when starting an executable,
except for fcb params which nobody uses anyways.
Did you debug it? Does it crash or so?
it works but is very slow (probably by desgin). Set cycles to 120000 or more if your computer can handle it.
1+1=10
Have a dual core 2.2ghz athlon x2 at home, running Vista 64-bit. I got the same results (garbled screen) with cycles 120000.
I didn't debug it but looked at the disassembly of the code. It looks like it relies on startup registers heavily to conserve space.
It uses FPU heavily as well. But if it already worked for someone, I guess it's me.
Be sure you try core=dynamic (or if you did that core=normal).
It does show the garbled screen at start, just wait a bit.
1+1=10
I got it running quite smoothly after changing core=dynamic and cycles=max .
Thanks everyone for help.
It's running in real mode, thus dosbox doesn't switch to the dynamic core/max cycles automatically.
