If possible use the function maxavail() and print the free heap memory while playing. This way you can check the free memory almost in real time.
Also, two more things: IX register is important for ZX Basic, so if you're not sure your ASM routines modifies it, better do:
on every ASM call
The other thing is that setting the ORG to low (i.e. 24000) leaves very very little stack space, and ASM calls, functions, SUBs, GOSUBS, etc might produce a silent stack overflow and the program might do those weirds things.
Perhaps this helps... :roll:
If you manage to solve, please tell us!
