[ASM] Tiny Program :P

Here's a 47 byte program that'll show a full-screen design, wait for a keypress, and then exit. (May not work in Vista if Vista doesn't support full screen)

(type "a" <enter> to run it :P)

if you beat it, add me onemorejosh@live.com :P

i beat it but ur not online on msn -__-

Yes i am, and you're not blocked, so dunno why you aren't seeing me

Lol so its a game?

Yum, the wonderful world of 16-bit ASM programming :D, I should continue learning it...especially with all those interrupts, I keep forgetting which is which and their parameters hehe. Beside that, 16-bit is old and it might be better to focus on 32-bit...but it's still fun ;)

Do it in x86-64 yo.

debug.exe only supports 16 bit :P

wow ASM is so confusing compared to java or c++.

Omg it's ASM.
The most confusing programming language I have encountered in my life.

Screenies pl0x :D

Try developing in binary. ;)

Also, a screenie would be nice.

Ok, here's links to screen captures...
