I didn't dig much, but here are some facts 1. we can downgrade dsi Firmware via Dsienhanced game cart: https://gbatemp.net/threads/dsi-downgrading-the-complete-guide.393682/ 2. we can patch the 3ds firm via dsiware game: https://github.com/Plailect/Guide/wiki/DSiWare-Downgrade There are known exploits for DSi Firmware Downgrade Via Biggest loser source: https://gbatemp.net/threads/dsi-downgrading-the-complete-guide.393682/ I know they are not the same, but maybe our EP could lead to whatever Fieldrunners' EP is it is also known that DSi enhanced flashcarts will not work for the DSi Firmware downgrading (I'm really not sure why). with the recent developments, discovery and success in the TWL field (yes as per github sources, we now how sd acccess, but thay may be irrelevant) : https://gbatemp.net/threads/ds-i-mode-hacking-progress-thread.413015/unread perhaps, maybe, JUST maybe. we can use DSi Enhanced games and DSi Enhanced Flashcarts to host our exploits. we would be hitting 2 birds, in concept from my shallow perspective, it could be a good POC. even after fieldrunners is pulled out of the eshop, we would still have access to these tools. what are your thoughts?
