Emulation of that processor was a bit of a challenge. Fortunately the fully general bit addressibility was only used in gzip decompression and the drawing instructions (circles, rectangles, that sort of thing) only came up in test mode. So not all of it had to be implemented and only the normal 8/16/32 bit addressing modes had to be fast.
