There’s a comment on the page.
For some reason, emulators (at least the ones I tried) wait 4x what real machines wait when you use BIOS int 15b 86h. You can tweak the code if you want to play at a faster speed.
There’s probably a sound explanation for this discrepancy...
- BGZq7 8y agoI can't say I entirely understand how the Elapsed Time Wait works, but testing in qemu, I was able to get it to a good speed by replacing the inc cl with a nop inc dx By opening in a hex editor, finding bf86 fec1 and replacing with bf86 9042 If you're on a very slow system, maybe just use 2 nops or a 2-byte nop.
- exikyut 8y agoI couldn't find "bf86 fec1". I did however find "b486 fec1". "bf86 9042" made it literally so fast I physically couldn't keep up. The following worked for me (w/ QEMU on old (no KVM) Pentium M), this may be too fast on newer machines: xxd cd.iso | sed 's/89c3 01de b486 fec1 cd15 b445/89c3 01de b486 9042 cd15 b445/' | xxd -r > cd2.iso (Note the creation of "> cd2.iso")
