You can find my Cross platform (ti82,ti83,ti83+ only) include file at
http://sgc.emu2k.com/dwedit/files/dwedit.inc

It looks for the description at "tTitle:", and looks for libs (SOS) at 
"Libs:".

Using #IFDEFs, one for calc and one for shell, it can complie for TI83 
(ZES,SOS,ION), TI82, and TI83+ (ION).

Use "#DEFINE TI82" for the ti82, "#DEFINE TI83" for the ti83, "#DEFINE 
TI83P" for the ti83+.

also use "#DEFINE SOS", "#DEFINE ZES", or "#DEFINE ION" to select shell.

It auto-replaces bcall() with rom_call() for compiling on 82.

there are a few "don't bcall this!" romcalls on the 82, they are:
_getcsc
_cphlde
_divhlbya
_divhlby10
_lcdbusy

this is called progstart in the include file

just bcall it and it should work, the 82 romcalls have been replaced with 83 
equivlent names

Yes, saferam1 is the apd_buf, 768 bytes of Free ram.
saferam2 is statvars, 512 bytes on 83, 768 bytes on 83+ (app_mem) and 128 
bytes on 82 (cmdshadow)

85/86 is 128x64x1024, 82/83/83+ are same (96x64x768)
