I assumed it woulnd't load from GS/OS because whatever additonal
overhead over ProDOS 8 would be stepping on memory locations that Alien
Mind would need.
On my ROM3 with 4meg RAM (Garret's Workshop), ZipGS 8Mhz/64k cache,
CFFA3000 in slot 7), I've found this:
Loading Alien Mind from System 6.0.4 (which loads ProDOS 2.4.1) freezes
at the ProDOS 8 load screen. This happens with a minimal extension set
or with a shift boot, enabling safe mode. I also copied the whole Alien
Mind folder to the same volume that's booting.
Loading Alien Mind from System 6.0.1 (which loads official ProDOS
2.0.3) it gets to the PBI Software load screen (with some graphical
glitches at the top), the animated title screen and then the main menu,
where you can view high scores, authors, change settings, but when you
start game, it freezes at a black screen. This was with the game on a
second volume mounted in my CFFA3000 and with the game copied to the
boot volume.
Reseting from the black screen causes some very funky weirdness on the
Apple IIGS / ROM info reboot screen I've never seen before. I have to
go into self test mode to get out of that, because reseting isn't
enough.
Now, this is what happens when booting System 6.0.1, but holding down
the '8' key to bypass GS/OS and boot into ProDOS 8 v2.0.3. Typing 'bye'
at the BASIC prompt takes you back to the old P8 launcher. Launching
Alien Mind from there, there is still a graphical glitch on the PBI
Software screen, but no other issues. The game loads fine and resuming
games also works perfectly.
This behaviour is what I experienced when booting from the qkumba's
original disk image.
So if it's working on your ROM01 from GS/OS Matt, then perhaps there's
still a lingering issue for ROM3 machines and runnning from GS/OS – but
please confirm if the game itself loads properly, beyond the main menu
(either start or resume a game from GS/OS).
