Revive an old handheld console
A PSP that sat unused for over 15 years now runs Muse, after its owner's agent ported the client to C, according to one person on X; holding a button and talking into the mic gets a spoken reply. With no detail on toolchain, time taken or reliability, treat this handheld console project as a starting sketch.
What you can get
What it is
Ported client on device
A long-unused handheld running a ported client, reachable by holding a button and talking into the mic.
It came back right when
- The console model and port target, language and toolchain, are explicitly confirmed, not assumed.
- You understand the loading method before it's used on the real device.
- The button-and-mic flow is tested on real hardware, not just described.
- Any failure during porting or loading is reported, not silently retried.
- You made an informed decision about homebrew risk to the device.
The checks are editorial, not from the source.
- Check the console's homebrew statusStops for your approval
What's known about loading custom code on this device.
- Plan the port
Language, toolchain, and likely failure points.
- Build and load
Ports the client and helps load it onto the device.
- Test on real hardwareStops for your approval
You verify the button, mic and response in person.
Editorial, not from the source
Works when
- You have a specific old handheld with known homebrew support.
- You're comfortable with some technical back-and-forth and possible failed attempts.
- You're doing this for the hobby value, not expecting it to be reliable.
Does not work when
- You need this to work the first time with no troubleshooting.
- Your console has no homebrew community or known way to load custom code.
- You're not willing to risk the device not working as it did before.

The source case
On X, @wobsoriano says they got Muse running on a PSP that had been sitting unused for over 15 years, by having the agent port the client to C so it runs natively on the device; holding a button and talking into the built-in mic reaches Muse, which answers with a voice from a connected provider. One example is given, checked on 2026-10-09, with no detail on the toolchain used, how long it took, or whether it kept working reliably afterward.

Source excerpt
Got @Muse running on the PSP that's been sitting in our house for over 15 years @alexandr_wang Had my agent port the gadget client to C so it runs natively on the PSP. Hold R, talk into the built-in mic. Muse answers, and OpenAI gives it a voice

What you need
Editorial, not from the source
You supply
- Console model
- What you know about its homebrew or devkit support
Connected
- A way to transfer files to the console
- A connected voice provider for responses
Approved by you
- Your decision to proceed with unofficial or homebrew software on your own device
How to try it
Editorial, not from the source
- Confirm the exact console model and what custom software it can already run, homebrew support, a devkit, existing community tools, since this depends entirely on what that hardware allows.
- Ask for a plan before any porting starts: what language the client needs to be ported to, what toolchain is required, and what could fail.
- Have it walk you through loading the result onto the actual device, rather than only testing in an emulator.
- Test the real hardware yourself, the button, the mic, the response, before assuming it works.
Know your console's homebrew situation first
Whether this is even possible depends almost entirely on the specific device, not on the agent. A PSP has a long-established homebrew scene, documented ways to load unsigned code, and a devkit ecosystem other people have already built, which is likely why the one report behind this page could get a port running natively on it. A different handheld might have none of that, a locked bootloader, no community tooling, no practical way to load custom software at all. Before asking for any porting work, find out what's actually known about your specific console: whether homebrew exists for it, what firmware versions it supports, and what other people have already managed to load onto one like yours.
Ask for a plan before any code gets loaded
Porting a client to run natively on old hardware means translating it into a language and toolchain that hardware can actually run, C, in the one example here, which is a real technical undertaking with real ways to fail. Ask what the plan is before anything gets loaded onto the device: what's being ported, what toolchain is needed, what parts are most likely to break. This isn't a formality, it's the difference between a considered attempt and a blind one, and a console that's been sitting for fifteen years is often not something you want to put unverified, untested code onto without at least understanding what that code is meant to do.
Test the real hardware, not just the idea
A port can look complete on paper, compiled, loaded, no errors reported, and still fail the moment you try to use it for real: the mic doesn't pick up your voice, the button mapping is wrong, the response never comes back. The one report this page is built on describes a specific interaction, hold a button, talk into the built-in mic, which only means something once you've actually tried it on the device in front of you. Treat the first real test as the actual finish line, not the successful load or compile, and be ready for the possibility that getting old hardware to cooperate takes more than one attempt.
Open Muse to try it. That is the product's own site; this guide is not part of it.
Limits and confirmation points
Limits to confirm
- One example, one device, a PSP, one specific port, to C. Other handhelds have different hardware and homebrew ecosystems, and may not support this at all.
- The post gives no detail on how long the port took, what broke along the way, or whether it kept working after the one demo.
- Loading custom software onto an old console usually means homebrew or unofficial tools, which can carry real risk to the device depending on the console and method.
- A voice response depends on a separate connected provider; what happens without that connection, or offline, isn't described here.
Stop and check
Editorial, not from the source
- Before it starts: confirm the exact console and its known homebrew or devkit situation.
- Before loading anything: understand what the port changes and what could go wrong.
- After it's loaded: test the mic, button and response on the real hardware.
If it goes wrong
Editorial, not from the source
- The ported client won't run on the device
- Check the toolchain and firmware version against what the homebrew community for that console actually supports; mismatches here are common.
- The mic or button doesn't trigger a response
- Test the hardware input in isolation first, does the button register at all, before troubleshooting the agent connection.
- You're not sure if this risks the device
- Research the specific console's homebrew risk level before proceeding; some are well-understood and low-risk, others are not.
Common questions
Will this work on any old handheld console?
Not necessarily. The one report is specific to a PSP, which has an established homebrew scene; a different device may have no comparable way to load custom code at all.
Is loading custom software onto an old console risky?
It can be, depending on the console and the method, since this usually means homebrew or unofficial tools. Research your specific device's risk level before proceeding.
What language does the client get ported to?
The example given ports it to C so it runs natively on the device. Your console's toolchain may call for something different; ask for a plan before anything is loaded.
Does the voice response work offline?
Not described here. The example mentions a connected voice provider; what happens without that connection isn't addressed in the source.
How do I know the port actually works?
Test it on the real hardware yourself, the button, the mic, and the response, rather than treating a successful compile or load as proof it works.
