I'm still curious about the build process back in the days. The LineF hack is 
currently implemented by a modified compiler/assembler. Surely they used 
something different. Also the way the ROM is linked in two parts currently is 
handled by linking the 2nd half of the ROM at the absolute address of the end 
of the 1st half, then putting them together with the mkrom utility.  I tried 
with partially linking, but that did not work: you still end up with two large 
objects that both have text & data, and when you link that, the data segment 
will be put at the end, as usual.

And some other mysteries still remain. The glued resource files are too large 
for example, and contain some garbage at the end that is nowhere used. Also 
those resource files are really strange, and cannot be changed without 
corrupting everything. And why they did some juggling with the AES global 
array when starting the copy/format dialog also is hard to understand.
