I've tried and tried, but the GBAtemp search function simply won't let me use search terms like "slot 2" and "GBA", which seems rather...anti-useful. Not even the mighty Google seems to be of help. Here's hoping a thread will work better.
I've been looking into hacking Mega Man Battle Network 5: Double Team DS in order to allow the use of the various slot-2 GBA-driven events and abilities (particularly the two Bass Crosses and Sol Cross) on 3DS. While the Wii U VC versions of the GBA titles do allow the use of the two Bass Crosses (and they've been ripped and converted to CIA successfully already), Sol Cross is (to my knowledge) still not available in those, and the rather large number of events driven by various GBA carts are of indeterminate status. Making BN5DS just work on a 3DS without needing a second cartridge slot would still be beneficial.
The trouble I keep running into is that, as far as I know, there's no way to spoof slot-2 data directly. Thus I put the question to my fellow tinkerers: is there now, or might there theoretically be, a method for spoofing data in slot 2 when running DS games on a 3DS, whether via commercial cart or flashcart?
(Yes, I'm aware DeSmuME can do this, but I'd like to have the ability to play the full BN5DS on the go, without needing an emulator to spoof slot 2.)
