heatsinks on the cpu and memory
OC to turbo
(i set memory split to 16mb during compile, 256 for regular use)
disable the terminal for serial connection
I only use SSH now, never use samba or the USB copying service (I never install/enable those)
Leave nothing extra plugged into the pi, including the keyboard (i only use a controller)
I then run a bash script with “sudo su”:

Please be careful, if you don’t understand whats going on you probably shouldn’t be using it but it should be safe.
If you are really hardcore:
1. do not use a splash screen
2. delete the simple theme for ES, use no themes!
3. do not use any scraped data for the games
4. compile just what you want, locally on your pi, don’t use the pre-compiled binaries if you don’t have to
the guys who maintain this project have done a REALLY great job at creating an extremely slimmed down image. i would work with that, delete ES/retropie stuff and compile just what i wanted or download just the binaries that i wanted
.
