NEO geo x controller adapter to AES?

[Hoagtech]

I just bought a NEO geo cd and I own the NEO geo X with two USB joysticks.

I have two handheld controllers for the CD and would love to use my NEO geo X arcade sticks.

Is a solution or an adapter that allows me to use my NEO geo x arcade stick on the NEO geo Cd or AES?

I don’t want to mod it either because I still use my NEO geo x and MAME pc and would like to keep the usb ends.

Also a bonus question. Is there a way to use the X arcade sticks with Xbox 360?

It would be a true joy to play metal slug 7 (xx) with the x stick but I realize it’s probably a dream.

undamned did offer USB to DB15 decoders at some point. No idea if they're still available or if they would support the NGX sticks, but certainly worth looking into it.
