Atari 8bit Note:
Use File -> Attach Disk -> Rotate Down to flip the disk.

C64 Note:
Hit Y when asked whether you're running from floppy. Alt-N flips the disk.

Macintosh Note:
The game starts with MAME's UI enabled. Careful: Escape will terminate the emulator.
Use Scroll Lock to turn the UI on and off.
Quit the game and use Special->Shut Down to end emulation to avoid disk corruption.

PC Booter Note:
The disk must be write protected; ignore the warning. To play this in any meaningful way,
you will have to make a copy of the disk; you're on your own for that one.

PC-98 Note:
This version has gorgeous graphics, however it is in Japanese.
