problems to export mame to launchbox for android

[PPITEK]

hello, I want to export my favorite mame games on launchbox pc to launchbox for android, it does not export my favorites, it copies the entire romset, why?

You have to manually select the games you want to export.

MAME is complicated; depending on your MAME set, you can't just pick and choose which MAME games to copy over. Unfortunately the entire set is often required. Since we don't know what type of set you have, we don't just copy those games only for MAME.
