Discussion on versions and sequence breaks
Andrew schultz, who was working with the original apple version, wrote in his gamefaqs guide that you can skip kalohn. (Don't know if he actually tested it.) This would save a lot of time. I tried going straight to the end and got rejected (edit: in both versions):
The genesis port (1991) is one of the latest ones, which means it might have all the sequence breaks plugged up. What's more, the only genesis version I see is REV01 which means there could be a glitchier REV00 out there. It seems as though the SNES version came out earlier, in 1988 (?!) but there is no (U) version for it. Interestingly, the (J) snes port came out much later in 1993 and has redone graphics with character portraits.
Kelly Flewin: I see in your useful guide, for square lake, there are a bunch of secret passages. I couldn't find any in the genesis game and had to do all the encounters. Were you using the SNES version?
