6 months ago, I had a dream of running RDR2 on an iPhone. I wasn't sure if it could be done, but I decided to try anyways, by building a general-purpose Windows PC games emulator for iOS.

I am extremely happy to announce that this dream has come true!

[madeira @madeira_app]

Red Dead Redemption 2 is running at 30+ FPS on an iPhone 18 Pro.

No PC, no streaming, fully on-device via Madeira.

x86-64 → arm64 with FEX
Windows → iOS syscalls with Wine
DX12 → Metal with the madeira-d3d12 runtime

What AAA game should we get running next?

[Will Faust @willfaustcuber]

@ravensclawx Wine + FEX + Vulkan

[Will Faust @willfaustcuber]

@Ez10Right @_Dyllie_ @madeira_app Well I’d love to release the code but I’m just protecting myself legally lmao

Mario Kart World on iPhone 18 Pro via my private nxnative fork.

Physical memory usage is fairly low due to implementing userspace file-backed memory (swap like).

Disclaimer: I will not be releasing the code for this project anywhere.

[Will Faust @willfaustcuber]

@MakoCW Very cool!

[Will Faust @willfaustcuber]

@PauGabar @1bluean Illegal in what way?

[Will Faust @willfaustcuber]

@1bluean @shubshub11 When I say “slop” I am not referring to all AI generated code, just the parts of it that are sloppy or badly written or unreadable. All of my additions to nxnative were written by AI, with only steering and high level ideas from my end. Tbh just thought it’d fun to share lol

[Will Faust @willfaustcuber]

@vsenart @ItsMegaChan @chef_of_games Correct actually

[Will Faust @willfaustcuber]

Mario Kart World on macOS via nxnative fork

[Will Faust @willfaustcuber]

@onejailbreak_ Appreciate the mention

[Will Faust @willfaustcuber]

@TaroTheCerelean Personally im just having a little fun and i dont even really play games at all lol

[Will Faust @willfaustcuber]

@Ma673 @RyDawgE_ crazy to call me shady when i never released any files or profited from this at all 😭

[Will Faust @willfaustcuber]

@4k_isn More like a port, but yeah essentially

[Will Faust @willfaustcuber]

@chrissotraidis @TommyJez17 It was developed almost purely using Claude Opus 5.5 xhigh

[Will Faust @willfaustcuber]

@DeborahDelores @_Dyllie_ @madeira_app lmao

@Mutation_King @d_buchan09 @jaflm2401 @at98103902 They can take down my post via DMCA, but not much else to my knowledge. I am not sharing any dumps or files.

[Will Faust @willfaustcuber]

@LuizHDRamos Ofc! Anytime :)

[Will Faust @willfaustcuber]

Sorry lmao the compression is so bad, but it seems to top out just under 6.5GB usage. This should barely run on 8GB phones like the iPhone 16. And actually it would run very comfortably with Stossy’s donor memory trick to bypass jetsam limit.

[wis 🔜 LAIC 2027 @wisl_an_]

@willfaustcuber That’s crazy man! How’s the benchmark looking there? Can’t really see it properly, do you think an iPhone 16 could run it?

[Will Faust @willfaustcuber]

@1bluean Throwing tokens at random things is not a huge inconvenience for me i guess lol, and I can still share it with a few friends

[Will Faust @willfaustcuber]

@ravensclawx Amazing!

[Will Faust @willfaustcuber]

@AnAverageGamerX Thanks, I’m enjoying :)

[Will Faust @willfaustcuber]

@xillusiaa @0xNikilite 🙏

[Will Faust @willfaustcuber]

@Hassaansaeed22 @BorntoPlay64 Well then it’s just gonna be rumors haha, until someone else does similar work and releases that
