Following previous SX OS v2.2 beta’s release, TX released the newest SX OS v2.2.1, which adding USB HDD Write Support and much more, like TX releasing a homebrew “libusbfs” library. Lets have a look at the list of changes from TX team of SX OS v2.2.1 BETA :
Support for *big* USB drives
In our last announcement we bragged that you were able to enjoy TERABYTES of content, which was technically correct.. but in practice you were still limited to USB drives with a capacity up to 2TB. This is now a limitation of the past, as you are now able to use storage devices with a capacity of up to a PETABYTE!
Fix USB disk directory scanning
Due to a small bug in 2.2 beta the subdirectories on your USB disk weren’t being properly scanned for content. This has been fixed and you can now rely on the same subfolder structure as on your microSD card.
Fix USB ethernet and keyboard support
The introduction of our USB disk support apparently broke support for existing USB peripherals that were supported by Nintendo’s firmware. Fixed!
Add USB drive write support
We have enabled write support for USB drives. In practice for SX OS this means that NSP files can now actually be deleted after installation. But this also serves a greater purpose.. keep reading!
Eject gamecard on USB eject
When you disconnect a USB disk while in the main menu the (emulated) Game Card will actually be ejected now. A small detail, but a nice addition nonetheless.
Improved LayeredFS support
LayeredFS suffered from incompatibilities with certain games, this has been addressed and fixed. If you find any more problem titles, let us know!
Add support for temporarily disabling LayeredFS by pressing X while launching game/application
If you want to skip loading your LayeredFS patches you can now hold the X key while launching a game/application. The game/app will start normally without any patches applied.
Further improvements to overall system stability..
.. and other minor adjustments to enhance the user experience. You know the drill!
Meanwhile, TX reveals, they have some cool news for homebrew devs. We are releasing a little library called libusbfs` that allows your homebrew to interface with USB disks very easily. Please find the latest library code here directly! Let’s look forward to popular homebrew apps adapting support for USB storage.
