I've added Island Adventure to the list.
My intention is to list original titles, not ports of other games or translations, so something like Mega Man would not be applicable.
Doesn't that disqualify Revival Chase then, since it's a Lock 'N Chase port using graphics from the published Gameboy version?
It's best not to be too discriminating as long as the makers/publishers aren't parasites. The originality of many of these games is questionable: Insanity and MB are "original" in that they're built from scratch , but they're absolutely clones. Mysterious Song is a port through and through, but it got a facelift and extra content. Revival Chase is a port without a facelift, so what? There are also two other games on the disc and the makers clearly set out to support the scene and release a PCE game. Megaman is a port/hack. Ys IV is a regionalization. Island Adventure is demo. Where does one draw the line? These are all shades of grey.
The purpose of a homebrew "Master" list isn't to judge creativity or elbow grease, it's to help new members find games and give independent publishers/programmers some much-needed exposure. Divide the list into different categories if you want, but as long as A) code was edited, B) the publisher isn't a parasite, and C) the game pertains to the PCE, it should be on this list.
Nothing anime4ever has done belongs on this list or warrants anyone's support: SFZ is a prototype he slapped on a CDR. Megaman is somebody elses work used without permission (on a CDR).
