Yeah it might be a feature someday like PiPlay. You can also modify /etc/emulationstation/es_systems.cfg. For each system you want to comment out put a <!-- before <system>and <--after </system>. That will comment out that whole emulator from showing up in you list. Example below for the Apple II.
<!-- <system> <name>apple2</name> <fullname>Apple II</fullname> <path>/home/pi/RetroPie/roms/apple2</path> <extension>.sh .SH</extension> <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ apple2 %ROM%</command> <platform>apple2</platform> <theme>apple2</theme> </system> <--Contributions to the project are always appreciated, so if you would like to support us with a donation you can do so here.
