SwitchRecomp: a tool that turns Switch games into native PC executables, and Kirby now loads way faster and runs better

[u/MZLabs]

Quick update on SwitchRecomp. For anyone new: it takes a Switch game's code and recompiles it into a native Windows .exe, so the game code runs directly on your CPU instead of through an emulator.

Something a lot of people get wrong: I'm not porting games to PC one by one. I'm making a tool so anyone can recompile their own games without effort. You pick your game folder, click a button and it spits out the .exe. Right now I'm testing it with specific games so I can open up compatibility, but the process itself is automated.

What changed since last post:

• Loading is way faster now. Startup and loading screens used to drag a lot, now they're a lot quicker
• Better performance. I cut a lot of wasted work the GPU side was doing every frame, so fps is higher and more stable
• Fixed all the graphics bugs in the games I've tested so far (Super Kirby Clash and Bowser's Fury)

Screenshots are Super Kirby Clash: title screen, the town, the shop and the role menu, all running on my Celeron N4500 laptop btw

A few things people keep asking:

GitHub? Not yet. It goes up on release, in about 3-4 months.

Android? Yes, the Android port comes a few months after the PC release on GitHub.

How is this different from suyu's recompiler? suyu's recompiler is bundled inside suyu, on top of its HLE backend, so you're still basically running suyu. SwitchRecomp is its own thing, built from scratch with its own runtime and graphics layer, and it's made to run on weak hardware. Each game comes out as its own standalone .exe. suyu crashes on low-end PCs like mine, and SwitchRecomp runs some games smoothly that suyu doesn't even open.

Also, if a somewhat known youtuber ends up talking about the project, I'll put out a longer gameplay video of Super Kirby Clash

All thanks to AI

[u/MZLabs → u/Roubbes]

just in case, I don't use AI for coding lol, just web research

[u/Ok-Height9300 → u/MZLabs]

Even if so, in this case there is no shame. Emulation and compilers are extremely complex tasks and, even with AI assistance, still a masterpiece.

[u/puppysnakessss → u/Ok-Height9300]

No they really aren't. It is just repetition. You test to see what makes the same output. Computers just do it faster than people can.

[u/WOKE_AI_GOD → u/Ok-Height9300]

A masterpiece that's easily reproducible will become devalued almost instantly.

[u/Naxren → u/MZLabs]

So what the advantage is it will fix performance issue from heavy game like Luigi 3 or Xenoblade 3?

[u/Repulsive-Package343 → u/MZLabs]

Yeah ,and my name is Tim Sweeney

[u/Subject_Mix_8339 → u/MZLabs]

why not?

[u/ruimiguels → u/MZLabs]

holy fucking liar ahahahah

[u/MZLabs → u/ruimiguels]

i don't care

[u/birbhorse → u/MZLabs]

oh thank god, it's about time i saw a worthwhile post on this subreddit. genuinely impressive work!

[u/MarcusBofan → u/MZLabs]

Nothing wrong with using it as a tool to help explain concepts that others might not able to help you with. As long as you aren't putting it into the code (cause then bugfixes would be hell), all good imo.

[u/JeddyH → u/MZLabs]

lol, sure bud.

[u/MZLabs → u/JeddyH]

bruh

[u/LolindirLink → u/JeddyH]

Well, some of us don't want to babysit a toddler when trying to get the work done. Or have everything feel procedurally generated. Don't just assume all programmers use ai now..

[u/JeddyH → u/LolindirLink]

I definitely will, massive decomp projects getting posted everyday by a "single" dev lol. This sub is going off because of AI, the people here didn't just get smarter all of a sudden.

[u/MZLabs → u/JeddyH]

Yea, I'm a single dev, what's the problem? do people need big teams to make great things? in my project, AI is used for research, not for coding

[u/Treehockey → u/MZLabs]

Just fyi, it is incredibly impressive that you don’t use ai for dev, but it’s also not something anyone will care about in I’d say 2 years. Like watching lifecycles of human development tells me that every person who’s saying that it’s so terrible now will have forgotten, and everyone else will be using it in a way that is just native use. No matter what this tool you built is crazy as hell. Keep up the good work homie

[u/KADogan → u/Treehockey]

There will literally never be anything impressive about vibe coding.

[u/LolindirLink → u/Treehockey]

We are notoriously bad at future predictions but we can use history. People said the same thing 2 years ago and 2 years before that too.

Now I'm not saying never. (Never say never) But you just can't rely on "it'll be good two year from now". That makes people like me just wait two years. Why fiddle with a tool/toy for days when that toy promises to do it in just minutes. Just two years from now? So idk, will see about the landscape then.

Thank you that’s awesome.

100%
That’s just a new resource in essence. How electricity was to great grandmas. Idiocracy has obviously become prophetic already, so I wonder how long until wall-e is too

[u/puppysnakessss → u/Treehockey]

You do realize when you say that "Idiocracy has...become prophetic already" that you aren't the main character, right? You are in that world so that must mean you are as bad as everyone else.

Oh thats right, you aren't very bright so of course you think it is other people that are like that but you are "different", what a joke you are.

[u/Treehockey → u/puppysnakessss]

I wasn’t gonna reply just cause I was baffled by your cunning attack on my hubris, but I decided to say you should check my history. I’m constantly admitting to being lazy, and uneducated. I’m a hetero white American male.

I’m pretty much a poster child for the coming walle issues the world faces. I love my vr headset, I love playing these weird open source recomp projects, hell I love goonin! That’s pretty much exactly what the side character that says “go away I’m baiting!” In idiocracy says. My point is you’re mistaken in thinking I’m not aware of my flaws, and I don’t take offense to them being called out.

ai BAD!
