Quite a nice music disk with good tunes which definitely deserved
a WHDLoad patch. The disk has been created with Bootleg 2.1 which
split the main file into 5 different parts. So the first thing
I did was to code a RawDIC imager to save these 5 parts to a single
file. Then I noticed that several graphics.library functions were
used to write the menu text so I first created a slave which required
a Kickstart ROM. This was done quite quickly but somehow it annoyed
me as I don't like demo patches that use OS routines. So I started to code
a replacement for the Text() routine in graphics.library which was
used to write the menu text. Coding the routine didn't take long
but I spent about an hour trying to find out why no text was displayed
at all, for testing I even saved the original bitmap and loaded it to
the correct memory location, yet still no dice, WTF? I almost
questioned my sanity when I tried one last thing: I replaced the
KickEmul slave that I used for all my testing with a "normal"
one which works without any Kickstart ROM. And lo'n'behold, the
menu text appeared in all its glory! I actually have no idea
why the text disappeared within a split second with the KickEmul
slave but now that it works I don't really care either. I actually
just used the KickEmul slave to save some time as I didn't have
to patch all OS routines at once that way. So much for the theory
Once that was finished another bug kept me busy for a while, the small
"credits logo" would appear at random positions, turns out it only
worked by coincidence in the original demo as the lower byte of register d1
was always cleared. So I fixed that problem too and added ButtonWait support
for the loader screen. If enabled the loader part will be displayed until
you press right mouse button, this way you can listen to the whole
loader tune if you like.
Not much more to say, I guess it was enough babble anyway. :)
Enjoy the music disk from HD.
