> Unofficial development for the system also continues on the 9front fork, where active contributors provide monthly builds and new functionality. So far, the 9front fork has provided the system Wi-Fi drivers, audio drivers, USB support and built-in game emulator, along with other features.
To be fair drivers for all that existed already but support was very very narrow in terms of variety. e.g. there was wifi support for like one or two cards but handled on a per card basis - kinda hacky. 9front now has a clean portable wifi interface that spans all the architectures so the Pi and PC have the same wifi infrastructure despite having different interfaces and chips. Same with PCI, it was refactored to be portable among all supported platforms, e.g. the Pi 4 and PC.
