I have the attract mode front end running on the diepi distro and used retropi to install mame4all and both advmames.
Mame4all works good under X but advmame is hit and miss.
.94.0 is locked to my monitor resolution and hit or miss speed wise.
.106 has lower res choices but speed again is hit or miss.
I’ve compiled libretto Mame .78 and that looks like its working OK but retroarch is a pain to setup.
Is there an advMame that works good under x on the RPI2?
Maybe an older version like .72?
I’ve found some info on RPI forums but nothing I could make work.
