firmware for nintendo switch or for all the consoles?

[marcelojnobre]

Why are there two versions of firmwares? one for nintendo switch and others for other consoles if you download the nintendo switch I will not have to use the other consoles or it slows down all the consoles including also the nintendo switch

to support a completely new console, there will be tons of new codes,
Cross Hair have no sufficient space to store all these by now.
