I can't/am too lazy to find a thread about the differences, but I do know off the top of my head:
The U.S. and CD versions have a slightly (read: 5 pixel) shorter horizontal resolution than the JP cart version in the hopes of reducing flicker. We know how that turned out. I can't see a noticeable difference in flicker between the two. You can, however, see the reduced resolution if you own both the U.S. and JP carts. The viewable area on the U.S. version is cut just a tiny bit short on the right side of the screen where the viewable area on the JP version extends right to the edge of the screen.
Ahhhh, thank you. I have the JP HuCards and CD. Not sure if I still have the US HuCard.
Oh, by the way, has anyone ever checked out what lengths Darius Plus goes to when hooked into the SGX? Here's an illustration...
Fantastic. Your illustration was very clear and informative.
Tangent:
R-Type Complete CD has Red Book soundtrack replacing chiptunes. I happen to like the Red Book, but I know many people do not. An option to play PSG in lieu of Red Book would have been nice, I suppose (Vasteel, for example, provides this option, but it is geared to speed up the flow of the game).
Selecting "Chiptunes only", however, always struck me as being wasteful. Surely the developers could find a way to utilize Red Book for another purpose?
It sounds odd, but I always thought it would be "neat" to use Red Book to provide an ambient soundscape that would play alongside a traditional PSG chiptune soundtrack. The PSG and Red Book would not be synchronized and would loop at different times. I know this sounds retrograde and backward-thinking (since it isn't the most efficient use of Red Book), but do you know of any early CD-ROM game (on any platform) that did this?
Will
R-Type Complete Homebrew CD be the first to offer this dubious option? (just kidding)
