And the trace begins... Pick-A-Dilly Pair

[Steve Nickolas <usotsuki@buric.co>]

I'm going to keep the index visible on this folder while I trace through 
the contents of the disk...

This is from Pick-A-Dilly Pair, RESET VECTOR crack.

I traced HELLO and immediately got wedged, but I don't think it's that 
hard.  It looks like it's a DOS 3.3 api call of some sort.

The folder: http://1.buric.co/pickadillypair
The disassembled HELLO is in the folder.

1. Interrupts are disabled.
2. Reset vector is pointed to the second instruction of the file.
3. The screen is cleared, text mode set, and the HGR2 screen blanked under
   it through an FPBASIC ROM call.  Through another call, it is displayed.
4. The keyboard strobe is cleared.
5. The mystery function at E81 starts reading a table and translating it
   into calls to $03D9 and $03B0.
6. A mystery value is stored at $1500 and $645F.
7. Pause.
8. A mystery function (possibly read from disk) is called at 15A4, then
   something else is read from disk.
9. Keyboard is cleared again, code jumps to mystery address $1594.

I guess it's time to break out my beat-up Beneath Apple DOS...
