I have some old programs I made using Turbo Pascal. Some of them did not work correctly. The most important problem is about function "86h", from "int 15h".

The following code is equivalent to a delay function:

1procedure makepause(ms:Word); assembler;
2asm
3  mov ax,1000;
4  mul ms;
5  mov cx, dx;
6  mov dx, ax;
7  mov ah, 86h;
8  int 15h;
9end;

The ms parameter is the time to "sleep", in miliseconds.

Unfortunately, it looks like DosBox ignores this.

I attached the little game I made in Turbo Pascal, long time ago. Source and binary included. It is needed to decrease CPU Cycles until this becames playable.

It should at least since I just tested it and works just fine in the DOSBox CVS (the CVS sourcecode available at their sourceforge.net/projects/dosbox page.)
I make builds of it on a weekly basis abouts. See my sig.

BTW: My highscore with your little game came out to be 180. Spanish text but still playable :p.

Yes, it works on CVS, but didn't work on 0.61 release.

BTW, it isn't Spanish, it is Portuguese (although there are only a few words in whole game). Thanks for playing my humble game! 😀

Don't tell anyone, but the maximum score is 255 or 254, because it is the maximum size of "worm" (I wanted to use only one byte to store it). 😉
