I am trying to make a program that detects how many times the user has pressed enter until the timer goes up

(it's not going as planned)

here goes10->V
startTmr->
0->B
checkTmr(A)->X
Lbl 88
If V>=X>=0
Then
0->T
Lbl87
getKey->T
If T=105
Then
B+1->B
If checkTmr(A)>V
Then
goto 88
End
ClrHome
End
If T =/= 105
Then
Goto 87
End
Lbl 89
Disp "Coins Earned:",B

-DISCLAIMER- : if this is the wrong way to go about asking this question (i.e. making a new topic) please tell me how to do it correctly.

So, I was making a character for Super Smash Bros Open for TI calcs, and I came across a problem; that problem being Hayleia (the creator of the aforementioned program) had specified how to make most of the character, and said that when making a character you would compile as a TI prog, and then convert it to an AppVar. She, however, did not mention how to actually do this, so I sit here with a designed Pikachu character, but with no way to put it in the game lol.

this might be a dumb question, but how do i make sprites that are bigger than 8x8 for characters?
(sorry if this seems silly, i am new to all this Calculator stuff )
