Hello and welcome to Reswitched Weekly, a weekly summary of the progress made by the reswitched team and wider community around homebrew development for the Nintendo Switch.

This week, some attention was given to Mephisto, pthread and C++ support.

What was done

Not much was actually finished this week. But a lot of stuff was worked on.

What people are working on

• @roblabla enhanced File Descriptor table to be atomic and thread-safe newlib#2.
• @roblabla is porting OpenBSD’s pthread library for the switch. This will give a common, standard API for creating threads, mutexes, semaphores, and spinlocks. Lots of wizardry abound. libtransistor#48
• @dvdfreitag is working on building LLVM’s libc++ for C++ support in libtransistor.
• @roblabla added multithreading support to Mephisto, and fixed a couple papercuts. mephisto#15
• @kgsws is working on Switch Doom, implementing client-server multiplayer.
• Work is still ongoing for GPU/Audio support.

What happened outside Reswitched

Two important releases were done by Yellows8 and plutoo:

• nxdbg, a debugger for the Nintendo Switch. It requires a private kernelhax to be used.
• A way to get webkit access with the Switch firmware 1.0.0, through the JPN version of Puyo Puyo Tetris. See here.

Call for participation

Lots of things could be implemented properly into libtransistor/newlib without much more reverse-engineering. If you’re a developer and want to give a hand, make sure to hop on Discord so we can coordinate work.

Things that need work on :

• Thread Local Storage, by implementing emutls.
• Implementing more services into libtransistor.
• Port some apps, like micropython, and make sure they work !
