FWIW once the STD GDV Mini preset loaded, it did run at 60fps. Only tried in Nestopia so far. That said, just being able to run it isn’t the whole ballgame for me. For a dedicated TV box I just can’t have three minute load times.
I’ll report back here if I make any gains.
Also I think this cpu is oem locked and might be physically unreplaceable. This isn’t a terrible emulation box. I could keep it and have a fully functional setup including 720p GC and a mix of native - 1080p PCSX2. I can run all 1990s era cores in RA with decent shaders and utilize overlays to fill out the 4:3 black bars… But these Mega Bezel shaders give a legit feeling of an old TV living inside your new TV. These are the most immersive shaders I’ve ever seen by far.
