Reswitched Weekly 17
Hello and welcome to Reswitched Weekly, a bi-weekly summary of the progress made by the reswitched team and wider community around homebrew development for the Nintendo Switch.
What Happened: Some general tools
- @roblabla made some kernel patches, allowing the use of various debug syscalls. See the gist.
- @fincs fixed nx-hbloader so that it can now be used alongside games. Note that this change limits the size of the heap to 500MB. Relevant commit
@TurtleP has released the first version of Löve Potion here
- Löve Potion is a port of the LÖVE framework
- Works on all firmwares
- The rendering portion was rewritten to use SDL, giving a huge performance boost
- @Qyriad added Windows support to Fusee-Launcher, and @myfreeweb added FreeBSD support! See the Windows commit or the FreeBSD PR
What Happened: Libtransistor Toolchain
- @misson20000 made libtransistor compatible with 5.x consoles. Note that there is still a bug haunting the 4.x version. PR here
- @kgsws Finalized the am-layer mode, making libtransistor graphics work correctly with the rest of the Horizon ecosystem. PR here
- @awernick implemented the SDL2 Joystick API. PR here
What Happened: MegatonHammer Toolchain
- @Thog made a pure rust reimplementation of elf2nxo that’s a lot more robust. Check it out.
- @Kitlith made the Megaton-Hammer IPC heapless, making its performance more predictable. See the PR.
- @roblabla updated Megaton-Hammer to Rust 1.26.
What Happened: Atmosphère Custom Firmware
- @ktemkin has been hard at work to get sdMMC drivers out there, and making sure they go fast.
- @TuxSH worked on various part of the boot process.
- @SciresM Fixed various exosphere bugs, and implemented BIS cryptography, allowing to read the switch filesystems.
What Happened: Switch Linux
- Audio drivers were added! See this commit
- @shinyquagsire23 got joycons to work (docked) in switch linux. The patches can be found here.
Call for participation
Reswitched is always looking for people to work on the various projects. If you want to give a helping hand, hop on the Discord so we can coordinate the work!
If you want to work on Atmosphère, feel free to send a DM to @SciresM on Discord. People can easily work on Fusée (getting the SDMMC driver to work, for instance) by using Fusée-Gelée, or work on custom sysmodules, starting them with nspwn or hekate’s KIP injection.
In the libtransistor department, a lot of things could be implemented without much requirements beyond “knowing C”. Below are a list of issues, of varying difficulty, that we feel the community could help on. If you’re interested in working on those, but need some help, feel free to reach out to @roblabla or @misson20000 on Discord. We’ll be glad to write some mentoring notes on what needs to be done, and to guide you through the process.
- Documentation work!
- Enhancing the libtransistor docs. You can take a look at this issue.
- SwIPC documentation. We need to make it easy for people to know what each function and service does.
- JIT API! We can call svcMapProcessCodeMemory, meaning we can JIT. See here if you’d like to pick this up.
- Thread Local Storage. Check this issue.
- Implementing more services into libtransistor. We’re lacking a bunch of things like NFC support and whatnot.
- Port apps and libraries. Make sure they work! We have graphics and audio, the sky is the limit!
In two weeks…
If you’re working on anything fun, please post on next week’s issue on GitHub. This way, I can include your stuff in here :D.
