Not sure, but maybe-useful point of comparison: I used an RPi2 as a Retroarch (Lakka) box maybe... oh, two years ago or so. At that time, it managed the handful of PSX games I threw at it just fine, which kinda surprised me, but almost no N64 games ran at a playable framerate—only one that really worked was Mario 64, which I gather is one of the best-optimized and lightest-weight games on the system. I didn't try PS2 because PSX was OK but from its performance and how the N64 was doing I figured it didn't have a chance. 16-bit consoles were pretty good. Couldn't run the full-accuracy cores for SNES but that's not surprising. Everything before that 100% fine. Filters (say, for mimicking a CRT) weren't feasible on the hardware, beyond the simplest ones. The software's gotten a bit better—I think the Rarch team has done some major work pushing more of the computation of later emulator cores, like N64 and up, onto the graphics chip instead of the CPU—so I'm not sure how the RPi2 would fare now. The only benchmark I can find compares the RPi4 to the RPi3, not the 2, and the 4's single-core performance measures 3-5x better than the 3 (wow!) so I'm going to answer your question with a very confident probably, pending actually trying it.
