Yes, Gamecube (and Wii) games are upscaled right up to 4K and they look great. Many games work in 16:9 widescreen also (Gamecube was originally 4:3). For many games there are even community high-def texture packs that you can add to make them look even better. [ Edit: Sorry, was talking about Dolphin here, not Wii U!]

[Edit: seems like you're talking about Dolphin. flatiron upthread mentioned a Wii U so that's what the question you replied to is about.] Wii U's max HDMI output is 1080p. Also I have not seen any information that it does upscaling at all, so if you have a source for that, I'd like to know it.

It actually struggles to hit 30 FPS in most GC titles still. Accurate emulation between vastly different platform stacks generally does not care about the raw performance ratio rather how "lucky" some of the hardware functionality can be efficiently mapped.

Yes, in terms of Dolphin's performance today, I don't doubt it. There are probably many more optimisations that can be made: Dolphin's AArch64 JIT is still pretty incomplete and inefficient compared to the x86-64 JIT, for example. My point is in theory, given enough time and effort, the Pi 4 should have more than enough power to emulate a 20-year old device. I'd argue that it's certainly not "way way too weak" as the…

The RPi4 GPU is very weak for the tricks that Dolphin does. Good luck to get Ubershaders running on that for example. The CPU isn't much of an issue. Emulating a platform at such a low level in real-time is very heavy resource-wise, by design.

I recently wanted to play the original Paper Mario, but sadly it's not available on Switch, only Wii U. So I decided to go the emulator route. Dolphin is so good that Paper Mario runs better as a Wii U Virtual Console ROM under Dolphin than it does as an N64 ROM under Project 64.

Dolphin isn't a Wii U emulator, are you confusing it with the Wii?

To elaborate a bit more on the GPU peak FP32 perf: > VideoCore VI @ 500MHz: 500 [MHz] x 2 [slice] x 4 [qpu/slice] x 4 [processor] x 2 [op/clock] = 32 Gflop/s which is the RPi4 config. compared to a Snapdragon 800: 147.9Gflops FP32, and that's still a very old part. And about the Wii itself: > With the Wii, Nintendo opted to go with an innovative control scheme, rather than to focus on processing power. It offered 12…
