Would it be possible to port it for the GBA? Like as a ROM perhaps? Or maybe for the DS (the new 3DS should run DS homebrew... right? I really hope so, since I'm going to get one when they come out!
) Here's my suggestions for controls:
GBA:
A - Use item
B - Swing sword
R - Interact/Lift stuff/hold to run
L - Monster logbook
Start - Open menu
Select - Open map
DS:
A - Interact
B - Swing sword
Y - Use item
X - Open menu
R - Lift stuff
L - Hold to run
Start - Open map
Select - Monster logbook
If changing the controls is not possible, here's my keyboard equal suggestions:
GBA:
B = Z
A = X
R = C/Shift
L = M
Start = Enter
Select = Space
DS:
B = Z
Y = X
A = C
X = Enter
R = C
L = Shift
Start = P
Select = M
Also for OLB and 3T too please if it's possible. My suggestion for OLB's teleport is L (monster logbook), or maybe holding down two buttons at the same time, say L and R? If there's any other unique controls for 3T, please post so I can input my suggestion.
