Re: Qix - Filecracked! (With Caveats)

[Steve Nickolas <usotsuki@buric.co>]

Replying to myself again.  I got it to load without compressing; it still 
needs 2 stages, and can now use a BASIC loader instead of requiring a TEXT 
loader.

http://1.buric.co/qixfile.zip

It still has the same garbled title screen issue.  It loads remarkably 
fast compared to the standard version, probably because it doesn't display 
THREE DHGR GRAPHICS (plus a Taito logo over the first one) while starting 
up.

Included are:

1. qixfile.dsk - the actual disk image.
2. qix1c.a65 and qix2c.a65, plus listings of their assembly.
   (These are QIXLC and QIXGO on the disk image.)
3. qix-base.bin - A dump of the contiguous 48K of memory at the startup
   point, created with AppleWin.
4. The remaining 8 files are a dump of the D000-FFFF block of memory in
   every bank (C = alternate D; "2" is assumed to be the main bank), as
   generated with the help of ApplePC (yes, I still use this from time to
   time) and EDM.

What may be possible is that some of the language card data is tampered 
with by the monitor and this could be responsible for the title screen 
issue.  The next attempt will be to write a tool, loadable from the 
AppleWin debugger, to save this memory without the assistance of EDM.
