Earlier images had overlocking enabled by default (medium overclock from raspi-config). This was not ideal, as it should be left to users to decide how much they want to overclock their set up.

I guess you didn’t adjust the overclocking on the 2.5 image ?

Also – for changing video mode – just press “m” before an emulator loads – no need to edit the es_systems.cfg
