Hi Mike,

Yes, I got your original email (but no others).
I've just re-sent my reply (but without the zip attachment).

The zip of my dev folder is here:
http://www.tomcharlesworth.pwp.blueyonder.co.uk/CybernoidDev.zip

It contains my AppleII source for Cybernoid 1 & 2; and also the python
script I used to generate the basis for the Cybernoid2 6502 code (I
then hand tweaked it – looks like I commented additions with “new”).
It’s a bit of a mess - lots of temp files mixed in! I’ve not included
the tools (eg. the assembler: acme085), you should be able to find
these on the net.

Btw. If you are running AppleWin, then you can load the symbol files
(cybernoid.labels or cybernoid2.labels) into the debugger:

. Boot the disk, and wait for cybernoid to start playing.
. F7 to enter (and exit) the debugger

> u 6000    ; disassemble from $6000 (base addr of player)

I used the zero-page $F0..$FF for Z80 registers. You can add watches
for these “16-bit pointers” in the debugger, eg:
(I found this useful when debugging the 6502 code.)

Let me know privately/publicly if you get anywhere with this.
