@lavanoid well there are several issues with that.... first thing's first, NATIVE_FIRM version, we have more than enough space to store some stuff in firm0 and 1 slots, but seeing that certain versions of firm aren't compatible with certain sysNAND versions, it's hard to make a solution that works for everyone, as there are already a few different schools of thought surrounding a9lh... Take for example, users (like me) who like to keep emuNAND, but keep that on 9.2 and sysNAND on the latest version, now we have to embed the 10.4 NATIVE_FIRM into the NAND, along with a payload to make it so they can load it... but what happens when they update to the next system version, and payload aren't compatible with the 10.4 firm? Well they're bricked until they can put this firmware back... then you have the users who want sysNAND to stay 9.2 and just use emuNAND for all of their needs, that problem is fairly simple to solve because they don't ever need to update the firm in NAND, but managing a good solution that supports both sides isn't exactly the easiest. That said we aren't giving up on it, however we have other uses for that extra space which will be more useful IMO than worrying about not having an SD card
