Oh, he writes in BASIC? That's not even a real language
Well, isn't many options for nspire than basic...
and there is a lot of workaround using spreadsheets, [these are why it's possible to do 3d graphs in nspire]
The difference is graph3 was written in asm, and 3d plot and nspir3D was written in basic.
I thought asm programs wouldn't run in the emulator...
as a lot of programs for 84 which are in asm can't run on it
