How to add games to MAME?

[Elaphe666]

I have the Xenocrisis rom and I have followed the instructions: copy xenocrisis.zip to the MAME roms folder, edit /hash/neogeo.xml adding the text provided with the game, and then run the game with mame neogeo xenocrisis. It works. Now I would like to add the game to MAME, so that it is displayed with my frontends. I have tried editing MAME.xml duplicating the section corresponding to a Neogeo game and replacing the rom name, title, year, etc. However, it is not listed by MAME nor by my frontends. Any idea?

Xeno Crisis is a 2019 multidirectional shooter homebrew video game

Homebrews won't be added to mainline MAME.  That's why HBMAME exists.

"It works." ==> You got this homebrew to run in MAME.  What's the problem?   

"frontends" - How many FE programs are you running?      Each one has different ways to add to the games list so mentioning which one(s) you are using would help.
