- Most R_SkinAvailable calls should be returning index into demo.skinlist (same numerical value as when demo was recorded), for demo sync
- A handful of general things permit exception for this
- Expose `replaynumskins` (calculated as `(demo.playback ? demo.numskins : numskins)`) to Lua
- There's *always* more that can be done for this, but this is the minimum spec that can at least be somewhat stable
- If emerald not yet collected on that cup, pick the first uncollected emerald, then get the cup's CUPCACHE_SPECIAL with that ID to pick the stage
- Already collected emeralds retain their swappage across gamedata saves
- Returns to normal order if you get all 7 OR Special Mode is unlocked (chao key? debug? password in modded games? sky's the limit)
- Pops up a Message from the Stars telling you the gems have been returned to their natural place
- Add-ons will always use their dedicated sealed star, since it's unordered material
If it weren't so last minute I could have a better solution for GP Backups, but right now what I've gone for is it always trusts whatever G_GPCupIntoRoundQueue does AS LONG AS THE COURSE ISN'T THE ONE YOU'RE RELOADING INTO. If it IS, then it checks to see if it's exactly what's been saved, and complains (with the generic error message, unfortunately) if it isn't.
