the data section at the end: you can make a generator for this and shave off some bytes.
Like:

Code:

;For example:
dd 0,0
; could be changed to
xor eax,eax
mov [blah],eax
mov [blah+4],eax

that blah should be further optimized to use registers or sth.

Madis731: Your example turns 8 bytes into 11; that's not an improvement.

Yeah, I know - of course it wouldn't be that simple - its not a complete example.

The definition of the data could be arranged into a loop where you generate pseudorandom data in eax and store it. The pseudorandom data would eventually be the graphics data. Finally you can make a generator for even more beautiful graphics and still have the same size. Just change the first constant that the calculation starts from...
...maybe I just have to post an example Very Happy

Hey vid,
what about a version with background music?
Its possible to do it in a ~4K version.

Okay, Eric Auer has tweaked vid's para512 to use 386-compatible random number generation, plus it has a score bar now (though it's too easy, IMO). It's 631 bytes now. He says his changes are public domain.

Tested new version successfully under WinXP (fullscreen DOS prompt, AMD AthlonXP), DOSBox 0.70 (WinXP, Intel P4), and FreeDOS 1.0 boot disk (my 486 Sx/25).

Believe me, my German is worse than yours, by far!

Anyways, I e-mailed Mr. Auer about something unrelated and mentioned / showed him the tiny paratrooper thingy you wrote, and he tweaked it and told me the direct link to get it. AFAIK, it isn't on his site under any obvious link. And he asked me to mention it here. Smile
