Hmm... Do we need an entirely-binary format here? What about:
#plex86-dump
version=1
# Registers
AX=0x0004323
...
...
# Heap
heap-encoding=gzip
heap-length=12345678
HEAP
<binary data for heap here>
Presumeably, the registers and other items will take up a fairly
insignificant amount of space, compared to the heap, so there's no
real loss in making it readable.
