It's GOOD xD
This is quite old code but there are plenty of usefull things:
-A pico script interpreter/compiler (might be too much big)
-A library of 89 bitmap functions <- this is gonna be useful

-TjanSAL, that might be a replacement for current scripting engine I think. Based on stack and with a postfix notation (It seems to me that also the current script engine makes use of stack, correct me if I'm wrong!)
-TjanScript another scripting implemented in Delphi but I don't know if this is too much big (source is 65 kb, but it surely could be cleaned up because it makes use of lots of components unneeded in games

Give it a look!!!!!
Bye bye!
