A small success!

I finally got _Slay the Nerius_ to run from disk!

I used a downloaded .ROM file (I do have the original Pak, so no
flaming!), converted into a .BIN loading at $3000 by adding the header
and footer.

_Slay the Nerius_ needs patching, and a patch is at
http://coco_docs.tripod.com/id91.htm  However, that is kind of a
minimal file, as it lists the patching pokes (for Slay the Nerious, at
&H5124 and &H5125) as absolute pokes, *without* mentioning where
exactly in memory the binary is!!!

Loading the ROM at $3000, the addresses are obviously wrong, as the 8K
file only extends to $4FFF.  I tried poke &H3124, and that didn't
work, so I tried it at &H4124.  Success!!!!

So, I suspect the patch list is based on the ROM image loaded at
$4000.

Now, pretty much all of my ROM paks have been converted to disk!
Woohoo!

Thanks to Robert Gault!
