It about how accurate the emulator is. ePSXE used to run fine on a 700mhz PIII with 128gb of ram. There were SNES emulators that also worked fine. However they were inaccurate and lots of games weren't exactly great. MGS for example didn't work well on ePSXe for years because it used many more hardware tricks than same the original ridge Racer. Ridge Racer R4 doesn't even work properly on a PS2 backwards PS1 compatibility because the PS1 on a chip isn't perfect.

>128gb ram I think you mean 128mb. Otherwise, that must have been some Pentium system!

Like I said, PS1 emulators like ePSXe run fine on everything. They would run fine on an Apple Watch. Modern GPUs (and even a PIII’s IGPU is “modern”) are scary compared to back then. Accuracy makes things slower, sure, but the PS2 emulators in question (like Play!) aren’t striving for accuracy. They’re striving just to get the darn thing to run. But there’s only so much accuracy you can trade off when the only thing you’re really being asked to do is push polys. What are you going to do; drop some on the floor? But actually, something like that might be possible. You know how the mobile port of FFXV looks—same game, lower-detail textures, all the models replaced with re-rendered low-poly versions? It’d totally be possible to build a PS4 (or any other 3D console) emulator that can achieve that effect “automatically.” We already have “HD texture packs” for emulators like Dolphin and Citra. We could have “LQ texture+model packs”, to reduce PS4/3/2-era graphics down to PS1-era graphics. That’d take most of the workload off the emulator, and let basically anything run these games. (And, in theory, you could compute such a pack automatically. For the textures, you’re just downsampling. For the models, 3D-geometry simplification algorithms exist, although they’re not realtime. But you could run them over a whole game’s worth of assets in a couple hours; and so, with disc images in hand, you could stand up a server and work your way through the whole console library over a few months.)

  Oh okay. I think I misunderstood what you were saying slightly. Some of the SNES/NES emulators require a lot of resources (relatively) to run accurately. I wondered if it was the same situation. So yeah it appears the GPU isn't capable. I do wonder what the performance numbers of the Nintendo Switch vs the RPi 4 would be.
