Re: Alien Rain into files (intact)

I spotted a .nib of Alien Rain (fine Galaxian type game from Tony
Suzuki/Broderbund), and since it had the original title screen and all,
I thought a file version in normal format might be handy.
<liberal snips>
The code starting at $B700 loaded the title screen stuff into
$2000-$60FF from track 1 sector 0 through track 5 sector C, and then
called the title screen routine at $6000.
After returning, it then continued by loading the game into $1000-$77FF
from track 6 sector 0 through track D sector C, calling the game start
at $7600 (which in turn just has a small loop to wipe out part of the
RWTS to cover its tracks and then jump to the real beginning at $1000).
All this stuff is already preserved in the .nib, so rather than just
converting/normalizing that to 16 sectors, single it's a single load
game (beyond the title screen), I opted to just save out the title
screen code and the game code as two separate pieces (using the game to
load each piece to capture).
Then I just created a lazy BASIC program to run the title followed by
the game.
It would probably be a good candidate to stitch together into one file,
with compression and such, but I'll leave that to others who like to do
that.

Something like this?
Also I found the string "TOSHINORI SUZUKI" in the file, perhaps the
author's full name?
There's some junk in the dump that suggests it was cross-assembled.
