what rom version are you using for the emu? have u tried it on ur calc? i
got 1.2 and most every line screws up....most of the time it displays lines
that are on the graph screen instead of a line (i have no idea why) so i
changed it so it goes to the graph screen and clears it then draws random
lines everywhere, but now it wont even draw one line right so i dunno :(
