My controller is an 8bitdo M30, recognized as "xbox" and in the settings, we have images of playstation controller symbols... When configuring it, we have to map buttons called "button" or "LB" and in the end nothing works.
Works not bad. But interface and options are not comfortable. Works without freeses on my old Athlon 64 x2 3800+ cpu, but only with default video settings. With video shader it works too slow.
Mint 21.1 Can't select rom. List is empty. Version 0.5.1.7 works without problems.
