Hi I'm new to the forum and i have a problem i can use some help with. This account is a year old and i forgot i had it as i tend to not use forums because i just lurk.

Using any mame emulator i get an error when i try to run X-men children of the atom. The error says that i'm missing the xcota.key and qsound files. I found a qsound file thanks to google but i can't find the xcota.key file. The qsound file also said it needed to be redumped and i don't even know what that means. I'm pretty sure their is an alternative for qsound but i can't find it... but the xcota key i have no answer for. I'm a novice with emulators so this is just my opinion but i think the xcota.key error may be cps2 related, and has nothing to do with me using windows 10.

I'm also using Mameui64
