Homebrew Discussion Play! PS2 Emulator is running on the Nintendo Switch!

[Billy Acuña]

Wait does this thing actually have an aarch64 dynarec? I refuse to believe it seeing how poorly it runs

This is pretty good actually considering the current status of Play! emulator.

Ps3 has the more powerful cpu. Switch has the better gpu and ram. Ps3 cpu is more capable than current gen console cpus

How did you reach this ridiculous conclusion about the PS3 CPU? By totalling clock speeds and counting the SPEs as "cores" (which is completely incorrect)? Or maybe you're just recycling second hand information online, which I'll admit is quite a common thing.

The PS3 CPU was one 3.2GHz PowerPC core with 7 usable SPEs available - they can communicate with each other, but they do not have branch prediction and are therefore incredibly poor when running changing/branching/modifying code; in other words, any code that isn't a straightforward execution or loop. The sole PPE has to babysit all 7 SPEs while also supplying the GPU with instructions and because of the long pipeline involved this was another huge performance impediment.
The PS3 SPEs also had just 256KB of local store cache and the main PPE had to DMA data from memory 256KB at a time, further slowing down the process.
Let's not forget that the Cell (like the 360 CPU) is strictly in-order, compared to the out-of-order nature of the PS4, XB1, Switch and even Wii - instructions must be handled in order, one at a time, so even if we assume the PS3 is a brute compute colossus it often sits doing absolutely nothing as it waits for the rest of the instructions to execute, wasting whatever potential compute it has left in a real game situation.
For these reasons, the Cell often doesn't even outperform the Xbox 360 CPU, let alone PS4/XB1.
Call it a strawman, but it's worth mentioning that the PS4/XB1 are designed to process on the GPU (which is very sensible, given the raw compute potential of gpus in general that is only now being utilised) and as a result, the system is intentionally balanced with GPU emphasis. The PS4 CPU is still far easier to work with and generally superior to the Cell, but in cases where the Cell does succeed the PS4 GPU is quick to compensate.

In some edge cases, the PS3 CPU outperforms the PS4 CPU in high density compute scenarios where the SPEs can simply rip through operations with no need to communicate or change any of their instructions (they are definitely good SIMD units in very specific cases) but by and large, the PS3 doesn't outperform the Xbox 360, Switch, PS4 or XB1 and is even (in theory) outperformed by the superscalar out-of-order Wii by the same "edge case" token.

Can run a PS2 emulator on the Switch but completely fails at applying a screen protector. LOLOLOLOL!!!

A ps2 emulator is gonna have to be written 100% from scratch to get any optimization on the switch. too much overhead ruing Linux then running an emulator.

total opposite. horizon will always be slower for homebrew due to Nouveau, no easy way to change that.

they are very very different skills, mine is the same.

Really amazing that many people are looking forward to playing PS2 emulator so badly on Nintendo Switch. Heh. I admit I do too. Only time will tell.

I must admit I'm baffled too

Good to know.

Any chance to add Play to Lakka as alpha

Nope, needs to be ported as libretro core first.

That might be possible but might be an ass of work

Why ? The compatibly is very low. No.

Simple I am Sure people will work on it and it gives us hope

I know.. they are working on it but do it right away on Switch doesn't makes sense since the games are low. Give it more time.

The point is that applying a screen saver takes little to zero skill. What are you guys doing to get so many bubbles? You can see the specks of dirt/dust in that pic.... you're supposed to clean the screen FIRST. HAHA! And then only remove a small part of the backing of the protector at a time. Not pull the entire back off then try to put it on.

Was a couple of minutes ago on the discord of play they want to push more fixes and updates for arm devices can't wait

That's good because they saw what Switch can do and they are push more fixes and updates.

^Last time we tested (not sure how much the RA vers + cores for PS3/360 are optimized tho).
Benchmark was tyrquake in sw rendered mode, can't remember if that was OC'd tho.

That's some crazy news never was thinking the switch could beat the ps3, maybe it wasn't crazy to believe we could emulate the ps2 in the future

Well, I fine-tuned the shit out of it for RA Switch
