IDK where else to ask it so I am asking here. If I do not touch any directional buttons, I move up-left. Anyone know what the cause of this is?

It's most likely your controller or the emulator i suggest trying ePSXe emulator it works for me 100%

I use keyboard

Try a different emulator

[quote=PeterAfro]I use keyboard[/quote] Keyboard Ghosting is when you hold down multiple keys at once, some keys and some don't go through. Directional buttons suffer the most, as you have experienced yourself.

That is normal.

Get a controller.
