I get a crash stating:
SHARC: PC Stack overflow !
This happens all the way back to 0.102 (when first was bootable/playable)

adsp21062_device is being reset periodically, which re-enables interrupts while still inside an interrupt handler. The resulting cascade of interrupts overflows the stack.
However, the proper fix might actually be to reset the stack pointer instead.
Proposed fix for 0.160 seems to work.
