This is my second Patchme and it's been revamped with little tricks and stuff and i deemed it worthy for crackmes.de submition.

I always like to patch things, i mean, who doesn't? it's fun lol. but almost all the PatchMe's out there, they are realyl easy, just like nop the message box or change the last condition jmp to jmp always or nop. so i decided to do this, to make a little bit of a challenege...

please READ the readme.nfo i added there. best viewed with an nfo reader btw =)

the .nfo has all the extra information on how to submit the patchme as well as "completion levels"

Gold place goes to the fewest amount of bytes, silver to the next lowest, then bronze, etc. read the .nfo, it has everything there.

I hope you have as much fun as i had making it!

gl guys =)

Can't even run it without debugger.
Maybe it's because of Norton, aarg i hate norton :|.

14. Jun 2009		lol, no that's not what i meant DisasmDisease lol

you probably changed some Bytes in the program, but you didn't add / remove bytes, so the total amount of bytes in the program after patching looks the same via proteperties.

but how many bytes you changed in the patchme is what i'm asking =)

obnoxiuos did a 5 byte patch/change on a jump, so he changed 5 bytes, but the patched program size is 12.288 bytes. =)
