I've traced down a bunch of random crashes in ALL my emulators to one
file, which I lifted off a PD emulator and kept using... disk.c.

I just continually fail to understand the disk code or the hardware it
emulates and so can't implement a version of my own, free of these bugs.
;_;

Once I can somehow quash this damn thing, I can move on to more important
things, like making Dapple's video code more realistic, and finally
merging in the advanced features of emu2, getting back to the basics of
portability, etc. etc. etc. until Dapple's a decent emulator again.

If you read French, visit the hackzapple.com site, or read Beneath
Apple (Pro)DOS, and you will get plenty of (maybe too much)
information,

Obviously... I've pored through the Beneath books and just have failed to
grasp it. (I...dunno. I...just can't seem to understand it. I read
and read and...it just doesn't come to me. x.x)

I find the "Protection malefique" section of HackZapple interesting
reading and sometimes repack games I find there. (Though some of the
games are uploaded to like Mediafire or something and got zapped. Not
yours...blk's.)

I've had to suffer through emulating a disk drive also. It's tricky
stuff, but I can help you if you need -- also I've updated my JACE
code to comment the inner-workings of the drive a little more so it
might help to look at an alternate implementation. I updated my code
to speed up the emulator to max when disk reads are active, since
there's no possibility that anything else can be interleaved with disk
access and it would otherwise take forever (well, like it would on a
real machine)

Controller and I/O implementation

Drive implementation (deals with the emulated disk image more
directly)

Hm. I suppose... Can't be worse than the code I got now, which is buggy
as hell and I thought it was something else to blame for years. >_> lol
