Since updating to firmware 16/04/26 I've found that games that were stable and running on the 240Mhz overclock now either hang before the main menu or reboot the console. Has anyone else experienced the same issue?. I'd email MNEMO but I have a feeling that he won't support overclocks.
To follow-up. Emulators and homebrew apps/games still work fine with the overclock. It's only official games that do not. I'd say it has something to do with the CDDA clock.
