@azurden it’s trivial to acquire mame roms of a certain version, but we can’t assist as per the rules. do not try and find roms and then determine their version after the fact - hundreds of mame rom versions so it will almost certainly be wrong. find the version you need.
Yup, confirmed. Don't install the Control Block module from the Drivers list if you're not using it and updating with Retropie 4.3.5, because it looks for it and if not detected, initiates the shutdown sequence.
