Hacking Why do VC need to be on sysnand?

[Raylight]

So im really exited about the digital ds games but why cant i play them on emunand without a copy on sysnand and is there hope of this being remedied in the future?

 

[Filo97]

it's because turning on a gba game reboot to sysnand

arm9lh is a solution, join the master race, won't you?

i did so will vc on just emunand be possible?

DSiWare =/= VC
GBA "VC" =/= VC
GBA is special in its own rights (AGB_FIRM) and so is DSi (TWL_FIRM)

so would digital ds games be fine when on emunand without it on sysnand?

no

 

[Raylight]

no

cant this be patched in the future?

No, there's no way around that and a9lh by itself won't fix that. You could boot into sysnand + signature patched (via AuReiNand or MiniPasta) though.

darn i want to get rid of emunand but its complicated

iirc, a9lh can boot into a sig patched sysnand. This would theoretically resolve this (and being that a9lh can theoretically be used to boot up something to restore sysnand in case stuff goes sideways, this is actually somewhat more viable now than it was a while ago).

why does it have to be sysnand though? thats what i dont get.

Because the 3ds reboots itself to play GBA games.

it never seems like it does that couldnt that be patched into emunand to make it no reboot into sysnand

AGB_FIRM loads a GBA cart from boot.

Im really stupid when it comes to this stuff. so this cant be patched to run dsiware from emunand i guess this is a hardware thing that patches cant fix?

Right. The AGB_FIRM CIAs work by emulating a GBA cartridge in the 3ds; the 3ds then reboots into "DS mode" which detects the GBA cart and boots that. It's for the same reason that DSiWare can't be run from EmuNAND; it reboots into the TWL_FIRM of the 3ds. So far there is no way to make it reboot to EmuNAND. GBA may be impossible, I'm not sure about DSiWare, but I suspect it's the same case.

Yes, for the most part. (It's not really a "hardware thing", but you know).

So either install DSiWare/GBA stuff on both sysNAND or emuNAND, or move to sysNAND so you only have to install them once.

Do you have a NAND backup that has the DSiWare?

no but i could make one i dont have any vc or dsiware though why would you need one
