Between emunand being on the latest version, and the ability to do all my updating and such on this FW, is there any issue with being on 4.5FW? 1. One thing is I just got a 3DS and really like the Streepass/Mii Plaza feature. If I am on 4.5, I can't update to the lastest version of miiplaza and would need to put the 3DS in sleep mode while in emunand to collect tags and such while on the latest version of the software correct? Or can I still get the latest version of that software on sysnand while staying on 4.5? 2. There is also no danger in downgrading a 3DS XL to 4.5 right? All 3DS XL are compatible so there is no brick concerns except the inherent brick concerns correct? Bonus question: Finally, if you play DS roms using bluecard, does the DS game think you are using a DS or DSi, do DSi exlusive features working using a blue card and 3DS on a DS ROM? If so, do DSi titles have access to the 3ds camera?
