I got a version specific to touchpads (gbc4touch) which says 0.8 on the inside.  I have two questions.

1:  The direction you move seems to be based upon where your finger is on the touch-sensitive part of the touchpad, not the actual buttons.  Can you fix that?

2:  Is it possible to get my savs or states off onto a computer emulator and exchange them? (Do any other emus support your saving formats?)

1: Unfortunately, TI didn't put actual buttons under the touchpad. Detecting direction based on where you touch it is how their OS works, too.

2: You can rename .sav files to .sav.tns and those should work (since it's the same save format that the real Game Boy uses). Save states, on the other hand, are not compatible between emulators.

It's been rewritten but should be similar. Could you tell us what's exactly wrong with it? I unfortunately don't own a Touchpad and have always relied on other users' tests.

Isn't it possible to move diagonally in some games?

Yeah, that image would be dependent on the method the game checks input with, not the emu. Envision it checking Up, then down, then left, then right, and returning upon the first match, without checking the rest. That would mean Up-Left would be Up, and Down-Right would be Down, etc.

The best way to get rid of the direction issue is to use the old version which used the numbers for arrows.

Did I mention I really don't like the touch keypad at all? I feel like changing the OS with a patcher so I could use my old clickpad, but unfortunately the easiest way would actually be to solder a wire inside of it to ground instead (I might have that backwards, meaning it might need to be soldered to VCC. So sue me)

Ok, so Ndless doesn't seem to be in fault, since it divides the touchpad area in 9 portions.

Actually, I didn't use Ndless routines for that version (since I was hackily hex editing )

I did use the same method to divide the touchpad, though.
