Well, the hardest thing I've ever made would have to be the programming language I invented in April this year. It's a very low-level two-dimensional progamming language for DOS that compiles to around 3K for most programs. It can do self-modifying code, PUT/GET in it's little world of two-dimensional memory, etc. I made an interpreter first in VB, but it became difficult to maintain and buggy (spaghetti code doesn't even begin to describe that mess), so I decided to make an inline interpreter in assembler. The compiler is relatively simple (it opens the assembled inline interpreter, inserts the code, and saves as a .COM file), but the inline interpreter is a real challenge to work on. If you want to try it out, I decided to make it freeware: http://www.parabolagames.com/?page=c...&p=twirq_1_0_0

If you try it out, tell me what you think .
