Mame help on Lakka

I have two mame files. One ends in .u2 and the other .chd. How should I go about putting these in the rom folder? Thanks for any reply.

I’m not sure about .u2, but for the .chd, you want to create a folder in your rom folder with the same name as the .zip.

Example: So if pacman.zip is in your rom folder, you’d make a new folder inside the same directory titled simply “pacman”.

Honestly though, I don’t believe you even need to make a folder. Just dropping the .chd into your rom folder might work, but I’ve never tried.

Thanks for the response. I’ll try it right away.
