The CubeXX is not powerful enough to use runahead on any core.
It will run PS1 at 60fps, with Hard GPU Sync on (which reduces latency a little), and even at 2xResloution (with occasional brief audio stutter)
If runahead is essential then the OG Cube is the way to go (or similarly powerful device)
I didn't mean to say that it's essential to have PSX run-ahead. I was just recently playing with some emulators on my computer, and I noticed that, before run-ahead, Retroarch had pretty noticeable latency on Harmful Park, and Mednafen had noticeably less. Similarly, I haven't really noticed any latency on Flycast Dojo on most games, but it's pretty noticeable on the Retroarch Flycast core, and that system doesn't even support run-ahead to counteract it. This is even with hard gpu sync enabled and similar.
It's a bit of a moot point, anyway, because I was looking into Rocknix on H700-based systems, and it appears to support Mednafen and I think also an additional PSX emulator, and I wouldn't really expect good performance on Dreamcast/Atomiswave/NAOMI, anyway (cool that it can run them at almost full speed, though!).
I imagine for arcade emulation, it's probably stuck with Retroarch using either MAME or FBNeo cores (and vanilla MAME does not seem well suited to keyboardless UI control anyway, which is something that RA does quite well). I don't recall CPS-2 games feeling worse in RA compared to MAME, so it might not even be an issue. For that matter, there's nothing saying that emulators will perform exactly as well on a handheld device as they do on my computer..
I would be interested in what your perception of the lag situation is overall, though. I know this is far too subjective to put
too much stock in someone else's experience.
I also do appreciate the info about PSX run-ahead being beyond the capabilities of the CubeXX.
