need some directions here

[jbarros35]

Sorry to open this issue but I have any other choice.
First oficial forum of retropie is probably one of the worst community ever, if I post there I'll get banned just for asking directions with some "grammar error"...
I have a retropie running on a raspberry pi 3. I have a game named Rival Schools wich runs slow at mame 2010, I just want it to run on 2016 for testing purposes. Unfortunately there are no option inside menu for mame2016 libretro to install so I think need to download it inside my raspberry pi 3 and compile and make some magic to run my game.
If you could provide some directions on how to do that I would be glad. People really need more compreensive guides for such thing, they shouldn't be so hack and complicated stuff... but asking some way to run my game using a new emulator, couldn't be so hard
thank you

Rival Schools is a 3D game on PS1 hardware, it will never run well on a Pi3. Maybe the Pi4 if it ever comes out...
