Context how I ran into this:

Memory direction top to bottom
LoadNextPart
jsr into a0 resp. fw_LastLoadedPart(a6)
Crash when CALLFW InitPart is executed
Apparently, the beginning of the part's entry code was zeroed out when returning from InitPart

I think fw_InitPart clears out too many longwords for the part's variables.

Thanks for reporting! I didn't know you were also using (trying?) it. Gigabates found (and fixed) the same issue last week, too.

I've decided to push all the updates since last year as a squashed commit, including the fix for InitPart.
