Hi! If anybody's interested, I have online AuxMemApple and ProDOSi for cc65. AuxMemApple is a group of alternate memory configurations that provide near-direct access to aux memory, dedicated string and memory functions to use it and usage of unused OS memory, and ProDOSi is a library of functions to use ProDOS almost directly to perform disk access. AuxMemApple can be found at c65 additions - Manage /memory cfgs at SourceForge.net, and ProDOSi at c65 additions - Manage /util at SourceForge.net. Try them out!
BTW: I almost fotgot about A2SimpleIO: it is an efficient alternative to cc65's standard and console I/O libraries if your text needs are small. c65 additions - Manage /ui at SourceForge.net.
