The patch replaces the computation of the delay loop value with the following code: ; cx initialization here l_wait: push cx push dx mov cx,0h mov dx,400h mov ah,86h int 15h pop dx pop cx ; MM1 read input function here loop l_wait @ripsaw8080 Thanks for explaining how the game originally slowed down …

With this patch it uses the PC timer which is cycle independent and it should even run smooth at max cycles. Currently, I use 2000 …

I have tried setting the delay to 9 (slowest), but even then I had two choices regarding MM I: a) I could reduce cycles until the game became unplayable slow and still could barely see the messages. b) Or I could run the game at acceptable overall speed and not even notice that there were message I …

Here is another solution for those people like me who cannot find a satisfactory cycles setting. Open the Hex editor of your choice and change the following three lines in mm.exe : 0000 0860: C3 51 F7 26 DA 00 B9 03 00 D3 E8 8B C8 D1 E8 03 0000 0870: C8 41 51 E8 90 FC 0A C0 78 09 59 E2 F5 B8 00 00 …
