Altirra Crashing Error

[snicklin]

Hi,

 

My Altirra 3.90 test 19 (and same issue with 18 and even 3.20 test 1) is crashing when running my code. I suspect that it has nothing to do with the emulator, more my code, but I am seeing some odd behaviour.

 

Can anyone explain this? I hope that I have provided sufficient information.

'o' is Step Over and will continue execution until after the subroutine at the JSR target address completes. You want Step Into ('t') to step into the subroutine.

 

Using either of these to diagnose the problem is a waste of time, though. Just use the History window and follow execution backwards to see where execution got derailed.

Thank you so much Avery! It appears that it was running code from the cartridge space $A000, while in theory it should have been running from the $2000 range. I'll sit down and work out what I've done wrong.

 

I've just started to use the History window, by the way, it is great. You're a legend!

Problem fixed. Logic problem. The History window was key to me solving this, great to learn new things.
