Disgaea 3 - Playable by how much?

Well, that's... scary. Does that happen in non-combat when moving? Does it happen in other games? (Tried SWAP which probably does not care about diagonals at all, and the Mandelbrot app which uses the analog sticks which works diagonally. Dunno of anything else that works and uses the D-pad.)

It seems a bit random... If you go into settings in combat, and change which direction up is (The camera is rotated, it could be either upper right or upper left, look at some screenshot and you will get what I mean) it stops moving down. Sometimes. When you pick a character with the cursor, and then where to move, it starts moving down again. But then it stops when the character has finished moving. Yeah.

Edit: No diagonals from the d-pad outside of combat, it takes the last direction only.

Are you emulating the dualshock controller to memory-mapped IO in the emulator or are you high level emulating button presses and mapping them to an internal state manager or something like that? I have worked on an NES emu but never finish it so I know a bit about that kind of stuff and how it can be programmd
