Various improvements and code re-organisation: Optimised assembler LCD rendering function for the iPod 5G by me and an optimisations to the sprite drawing routines courtesy of stripwax (these improvements make pacbox almost realtime on the iPod 5G). MENU+SELECT now brings up the menu on the iPod instead of the hold switch.
