So..I programmed walking, but there's a problem:
1. It walks too fast!(Wow. Axe is sure fast)
2.Character keeps blinking
3.Have no idea how to do collition course.

Can you guys help me?

I'll post my code:
:.DEMO
:prgmA0000001 //Tilemap Sprite
:prgmA0000003 //Character Sprite
:[060606060606060606060606 -> GDB1
:[060606060606060606060006
:[060606060606060602020206
:[060606060606060602020206
:[010101010301010101010101
:[010101010301010101010101
:[060606060606060606060606
:[060606060606060606060606
:0->A->B->C
:Repeat getKey(15)
:sub(MP
:Pt-Off(A,B,C*8+Pic201
:DispGraph
:If getKey(2) and (A!=0)  //!=  not equal sign but I don't know how to write it, so...
:2->C
:A-8->A
:Pause 100
:End
:If getKey(3) and (A!=88) 
:3->C
:A+8->A
:Pause 100
:End
:If getKey(4) and (B!=0) 
:1->C
:B-8->B
:Pause 100
:End
:If getKey(1) and (B!=56)
:0->C
:B+8->B
:Pause 100
:End
:End
:Lbl MP
:For(Y,0,7
:For(X,0,11
:Pt-Off(X*8,Y*8,{Y*12+x+GBD1}*8+Pic101
:End:End
:DispGraph

More Info: Pic101
00=Tree
01=Water
02=Grass
03=Bridge(V)
04=Bridge(H)
05=Ground
06=Nothing

Pic201 is in this order:
Front,Back,Left,Right

Due to the rand calc reset, about half of the files are gone...
I backed it up, but it was long time ago...
So I'm thinking about not giving up and try with axe this time since the games started to get slower even with the optimization anyway. One question: how do you draw rectangle while still keeping a picture on screen?

All right! That's what I'll gonna do!

I'm always wondering why gbc4nspire can't run gba stuff
GBC and GBA stuff looks similar except for the quality of color.

721 You have omnimaga in your nspire

I hope that axe supports 4-layer(?) sound like quadplayer.(Or is it possible already and I just don't know how?)

I don't know why. I got the rom and tried to run it, it says it can't find it.
When I drag a rom file into batch file and try again, it says that nspire.emu is not a right batch file.

I need layout
