OK. I put them all up even though there is still work to be done. I still have to find a way to position them nicely so that, for example, the bottoms of springs all line up, etc.. I'm pretty sure I saw this kind of data in the J2A file somewhere, but I won't get a chance to go digging for it for some time, so this is what you're stuck with for a while (weeks?) (unless someone proposes an easy-to-make change..)..

enjoy?

EDIT:
may as well throw out a few thankyous at this point:

dr eggman: for his work on j2b format and code for getting raw data that was a starting point/inspiration
doubble dutch + n00b: for their hand ripped sprites which I used for comparison when extraction wasn't 100% accurate
mono: for technical advice
unknown: for menu palette and hand ripped sprites
