@dankcushions Thanks for your very elaborate answer! I naïvely assumed that at least the region detection was straightforward (e.g. some flag in the internal ROM header), but after some reading it seems that the region was indeed only "coded" physically by incompatible cartridge sizes. Some bytes of code and data saved I guess.

I'll just manually set the 50Hz rate. I'm definitely grateful that it can be done conveniently in a few seconds!

@madmodder123 no. Rpi update isn't really recommended unless you know what you're doing/have a specific use case as it can cause bugs. If one wants to start with stretch they'll need to flash the latest beta then just update from the setup script/ normal raspbian packages

Thanks for that elaborate answer. I need to step through this now.

@SuperMagicom said in switch between Emulation Station & Attract Mode:

There are scripts for this in the Motion Blue base image.

thanks for the help,

are these scripts available without having to download the Motion Blue image?
if so where can i get them?
