Hi,

Sorry, i don't speak spanish. I translated your text with an automatic translator. The result was not clear. But i guess you are trying to use AtomicFE with a something pluged on the Parallale port? May be PC2Jamma ?

I guess you have to install a special driver for your Device. Then , outside Atomic, test it. Check if it works as a "Joystick" or as a "Keyboard".

If it works as a "keyboard" , it should work without problem with Atomic , but May be key code sent are not the "mame" default. In that case, use AtomicKeys.exe to change key configuration.

If it works as a PC "Joystick" , Atomic should support basic function. (browse the list, run a game , etc..)
But if you need more customisation , you will have to use a software like Joy2Key that converts Joystick input as keyboard input.

I hope it helps.
