I wanted to play the Doodle Jump tie-in for Hop (2011), so I rebuilt the old App Store. Then I needed something to run it on, so I emulated an iPod.
Both free and open source. Links below.
Managed to upload iBSS to the emulated iPod Touch 2G and load it! Loading iBEC seems the next natural step. USB logic can be found here: github.com/devos50/it2g-usb-…
Worked on getting the USB connection working between the host machine and an emulated iPod Touch 2G. I can currently read the DFU status, next is the iBSS upload so we can initiate the recovery process! Source code: github.com/devos50/qemu-ios/…
Big thanks to Github user daniilfigasystems for adding brightness support to the iPod Touch 2G emulator! 🎉 A great enhancement for user experience. Try it out yourself here: github.com/devos50/qemu-ios #qemu #ios #opensource

Privacy is back 🎉

Tribler V8.0 is here. Anonymous downloading now faster than ever. Rusty Python replaced with Lightning Rust. Review of all code, had to dump old QT GUI, maintainance🙄 Make-over after 19 years! #Bittorrent #P2P #Tribler #Bitcoin #TUDelft
No problem at all, feel free to reuse or republish my diagram however you wish!
I actually wanted to contribute to the wiki but haven’t found the time to do so.
Absolutely amazing vibes in the arena section of the Dutch GP, looking forward to the race today!! #dutchGP #f1 #Zandvoort #Formula1

Digging through the new 3B Apple Intelligence Model on Sequoia and found some interesting things. The base model itself seems to be around 1.7GB. and most of the new features like priority notifications, text-image, localization, guardrails etc. are just prompts to the LLM.

Fuzz your engines
@devos50 Finally accomplished bi-directional communication! Ready for AFL++ instrumentation
Get ready for @_ringzer0 training on QEMU internals to fuzz what the fuzz you want!!!

I found binaries and ways finally to output commands on the filesystem. This is just an example of ls through syslog.
Almost ready to plug the AFL++ for my @_ringzer0 #BOOTSTRAP24 training.

The credit for this great didactical tool is all for @devos50
I will present my work on the emulation of legacy Apple devices at 37C3 in Hamburg. Feel free to send me a message if you want to chat! #37c3 fahrplan.events.ccc.de/congr…
My blog post on reverse engineering the iPod Touch 2G is now online: devos50.github.io/blog/2023/…
I did look a bit into it but there seems no public documentation for the older PowerVRs. Fortunately, I’m able to sidestep the GPU and enable bitmap rendering in Springboard. You have any link/reference to some other PowerVR implementation?
I created a diagram of most hardware components of the iPod Touch 2G. I tried to group components by functionality/logic. Most of the stuff related to display, sound and graphics is not finished yet (like the GPU).

Succesfully installed Windows 11 arm64 via NATIVE virtualization on my iPhone 14 Pro Max via @utmapp
Bootup time is roughly 25 secs from the poweroff state to the desktop.
I will present some of my work on the emulation of legacy Apple devices at FOSDEM'24 in Brussels (3-4 Feb). Happy to meet and chat! fosdem.org/2024/schedule/eve…
