I've spent a very pleasent day slowly shifting through the sprite source and doing some micro optimisations; that is removing unneeded instructions and the odd cycle here and there. It'll have no huge impact, but it might help compensate for when I do the cache linking everyframe. The idea (as Ive said before) is when a frame from the cache is used, I remove it from the linked list, and add it to the bottom again (the end). This keeps used ones in the list, and unused ones drift to the top.
So, now I've dont this, I'll go and put the code in to actually use the cache properly and see how it all holds together.
