Reswitched Weekly 13
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.
We’re doing two weeks for the price of one this time. SciresM started working on his CFW, Atmosphère. The Switchbrew team released HBL. Lots of interesting developments.
Switchbrew team released nx-hbexploit300, a 3.0.0 loader that works much better than ROhan! Among other things, it allows us to access the SD card, and a bunch of new syscalls, such as
svcMapProcessCodeMemory(useful for JIT) or
svcReplyReceive(useful to create custom services). To complement this, they also released nx-hbmenu, the “official” Homebrew Menu.
In light of this, @misson20000 fixed a couple bugs in libtransistor to make it compatible with the new hbl.
What people are working on
- @roblabla is working on bringing SD Card support to libtransistor. PR 109
- @roblabla also did a bunch of fixes to his SwIPC code generator. PR 9
@misson20000 is splitting up the
ace_loaderinto multiple modules. PR 103
- @TuxSH is working on porting FTPd to the switch. This is very useful for developers who want to reduce their edit-build-test cycle. Look at the switch_pr branch.
- @TurtleP is working on LovePotion. Work is ongoing in the input handling department. Look at LovePotion’s switch branch
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!
More specifically, if you’re interested in working on Atmosphère and have the relevant experience, send a DM to @SciresM on Discord.
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 on Discord. I’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! The new hbl allows us to call svcMapProcessCodeMemory, meaning we can now JIT. We should make sure we have a proper API for this. Mimicking mprotect would probably be the best past, to be compatible with existing code.
- Joystick support in SDL2! If you want to pick this up, look at this issue.
- Thread Local Storage. Check this issue.
- Implementing more services into libtransistor. We’re lacking a bunch of things like USB support and whatnot.
- Port apps and libraries. Make sure they work! We have graphics and audio, the sky is the limit!
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.
