I don't have the original. I was only working from the nib file.
I'm glad to see it's a hard scheme, and I'm not just a dunce. :) |

It's amazingly time consuming. I'm guessing this isn't a custom virtual machine, it's a commercial BASIC compiler since it has so many instructions.
I'm up to 31 instructions now and some of them I've skimmed over poorly since the functions they delve into are quite large.
It's hard to find motivation to put the kind of time required into this one since the game itself isn't very good, and this seems to be a one-off protection. It'd be nice if the knowledge gained from this could be used towards other titles, but it seems unlikely. |

Please don't give up on it though.

Come to think of it, an easier way to figure this one out is to write some simple BASIC code and compile it with some known BASIC compilers, then disassemble the generated code to see which one matches W.A.R.'s.
Once you figure out what compiler was used, it's pretty straightforward to decompile the unknown tokens. |

rtl64, simon's basic, blitz compiler, and austro-comp.
Those are the 4 basic compilers I am aware of. |

Abacus Basic 64 compiler can compile to either p-code or machine language. Also, there are two different compilier/optimizers. However, at the beginning of the compiled executable there is text stating "1984 SYS 2078 BASIC 64 V1.03". |
