Re: 1K Sudoku Solver

I'm using FASMW-ZX.EXE version 1.71.01

If there is a new version out I'd be interested in having a look at it.

Re: [TUTORIAL] How to disassemble ASM in VB81 XuR ?

It's rather ironic that I was working all this out only a couple of weekends ago to disassemble and old program for mine so I could replace the basic bits and make it 100% machine code. So only after I'd done it myself do I see this guide. Never mind, thanks for posting it.

Re: New to the ZX-81

You bet I did. I just totally copied the code you'd put into the 1K Jewel game and used that. So this program does not ever use the Basic system.

Re: 1K Sudoku Solver

@ Moggy I found the problem. The zero to indicate stop went missing in the change over to the new compiler from the other compiler I had written it on. If I input your clue numbers and hit solve, it goes around and around until it stops with no solution found. I tried your clues with an on line solv...
