The raycaster routine is a gigantic unrolled loop (how else is it so fast? ;) So to make room for it and all the graphics, Martin moves Prodos out of the way.  Aux bank is used for all of the Plasma code.  Basically the memory allocation scheme can be summarized like this: "I drink your milkshake.  I DRINK IT UP."  We use every scrap of memory we can get, and eventually will expand it further to take advantage of RamWorks and/or slinky cards.

In most cases, data is allocated and deallocated on the fly, so having large contiguous regions of memory to work with presents many advantages.  Our engine reads from disk less often than Ultima V when you walk around the map. :D
