Silly question
160x120 = 19,200.
The DSP only has 32k words of space doesn't it? So 16k words each for X and Y memory?
Will your 19,200 size buffer be overlapping high memory where debugger code lives?
Logically your buffer in X memory will be from x:$200 to x:$4d00.
I think x:$3f00 maps to p:$7f00 and this is the debugger code area, and your buffer might trash that code.
(Forgive me, I'm very rusty on DSP stuff. I might be *totally* wrong)

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
