But that retention rating seems more related to Japanese corporate dynamics, the whole silent contract of dont ask for more and we won't raise prices. Anyway if the entire OS is hand rolled how are they able to get WebKit and Nvidia drivers to run without much effort. Like I'm assuming they very much needed to build their own linker, their own executable format. Even their own libc, sounds like a lot of work to QC, document and implement. If it were their own flavour of Unix I wouldn't have so many questions. Unix already defines standards pretty well like file systems, process management, scheduler, drivers, a plethora of helpful daemons. So is it basically just a highly modified Unix, implying a lot of Unix things just has to be ported over to their micro kernel Unix or is it more proprietary. I ask this with just a thirst for this knowledge, I talked to a few enthusiast OS Devs that build their own toy kernels, bootloaders etc. from scratch and those things, though being great accomplishments, still have huge pains they never stop talking about. Like USB drivers are notorious to implement because of the standard being so complex. If Nintendo made their OS entirely from scratch did they go through all of that.
