Differences between SNES versions? (input very welcome)

I'm beginning to look into the differences that exist between different versions of DKC for SNES. I'm aware that there are at least three different regions for which this game was adapted, so there are PAL, NTSC and JAP (perhaps more...?). There are also numerous revisions that were released for each region, I think they would be primarily bug fixes.
If anyone has a full list of releases and revisions, that would be very helpful.
I'm also very curious which version(s) the Wii's VC system uses. That curiousity is a big part of my reason for starting this thread. From lots of observation and record keeping, I've come to think that the PAL release(s) may include text that the NTSC version(s) may not have. Cranky seems to use phrases in my PAL game that don't appear (at least I don't think they do) in my emulated NTSC 'v1.2' game.
Also, it seems that if you pause the game while swinging on a rope/vine, you will have continued to swing, just not visibly. When the game is unpaused, your position and the rope/vine's might be instantly 'teleported' to match where you would have been by then, had you not paused it. This seems to only happen on NTSC, because it doesn't happen on my PAL game.
Any thoughts or contributions are appreciated!
Note: If people have knowledge regarding DKC2 and DKC3 versions, please start new topics on the applicable boards. Thanks.
