Versatility by The New Image

for the Gameboy '98 Demo Competition
(c) The New Image '98
---------------------
Tools used:
TASM v3.0.1 : Using v1.5 of Jeff Frohwein's GameBoy-table, with a few
corrections and modifications by me.
MS QuickBASIC 4.50 : Used to quickly hack up some utilities, like a graphics
converter and a music editor.
Paint Shop Pro v4.14: Used for all graphics.
Tested with the following emulators:
VGB-DOS 0.88: Use -delay (default for v0.8b1) and -verbose 0 commandline
options. Gives the BEST result! (Perfect image, good sound.)
NO$GMB 1.4a : Perfect image, but the sound is bad (off-key, badly emulated).
GB97 v0.297 : I can't get this emulator to run at full framerate, it seems
to ALWAYS skip a frame or two! Besides this the image is rather
good, it has a problem with the last scanline though. I had to
use 8x8 sprites to work around another glitch, I'm not sure
whether GB97 is handling 10+ sprites/line right and all others
wrong or vice versa.
The sound is reasonable, but is an octave to high and irregular
(bad vblank-timing or related to the frame-rate thingy?)
VGB-WIN 1.0r: Use Delay Line-interrupts setup-option. Perfect image, sound is
bad (bad emulation).
So it's best to use VGB-DOS 0.88. On my system VGB-DOS plays all sound an
octave too high in a Windows95 DOS-box, so be sure to run it in true
DOS-mode! (I've checked correct soundpitch against my real gameboy.)
I hope everything works on a real gameboy too. I'm unable to test this, since
I don't have a flash-cart or something similar. It's on my want-list however!
Enjoy!
