I think I have to explain this a little better...
It does NOT connect to an emulator, another ti nspire or anything
It DOES switch Pokemon between two save files:
To trade, do it like this:
1) your friend sends you his savefile
2) You put both your and your friend's savestate in your "My Documents" folder and name them 1.sav and 2.sav
3) start my tool, select which Pokémons you want to trade and click trade
4) send 2_after.sav to your friend
Of course, this isn't the fastest way ever, but it's made for school and there you have time enough.
Also, you must know that this is a) the first c program I wrote and b) the first for a calculator
Normally I code with c# and java (i hate it but in school, we have to do some stupid stuff in a stupid way with it)
edit (years later): Seems like Java is actually pretty cool and the teacher was a retard
Hope it's clearer now, if not, just ask me
