Still have a few questions about what flashcart I should choose. The DSTwo looks like it might be the best fit, but it also looks like massive overkill, and I hear it drains the DS's battery a lot faster due to having additional CPUs on it.
Right now, I have a CycloDS, I got this thing years ago in place of my R4 (I don't remember what kind, but it was extremely old and didn't support cards over 2GB, as well as many many games at the time). Many of the later DS games however don't work on the CycloDS anymore, even when I patch some of them, and it does not work in a DSi or 3DS. This card is also not updated anymore, last firmware update was sometime in 2010-2011.
I also have a 3-in-1 Slot 2 card that works as a rumble pack, memory expansion, or I can flash a GBA game to it.
Right now, the main thing I want is a good card for my DS that can run any DS game without needing to pre-patch it. I really would heavily prefer it if it can run in my DSi/3DS as well. Did any cards actually natively support the DSi/3DS, or do all of them just pretend to be a random DS game? I know that at the time, there was actually an updated version of the CycloDS called the CycloDSi that actually appeared as itself in a DSi and could run in DSi mode, instead of appearing as a DS game and ran in DS mode (the last firmware update also added 3DS support, but I am sure that was patched out long ago on the 3DS). I really would prefer a card that works in a DSi/3DS without mimicing another game and just being in DS mode if there are still any like that.
I also would want it to be compatible with my 3-in-1 Slot 2 Cart and allow me to flash GBA games to it, would prefer to run the games natively over Slot 2 than emulating them. (Would this have any issues with transferring/backing up my savedata from Slot 2 this way?). I was actually able to use my CycloDS to dump my GBA games and backup/restore their savedata, as well as my CycloDS in combination with my 3-in-1 to dump my DS games, and again, also backup/restore their savedata. I would like to still be able to do this.
Finally, my 3DS systems are already hacked, so ntrboot isn't really needed, but it would be a plus if it was compatible with it, though the other two things take priority over this.
I do not need it to play 3DS games.
Are there any DS cards that fit all of this? The first post doesn't mention anything about how the DSi support is implemented (if it actually appears as itself in a DSi/3DS or if it just appears as a DS game, and if so, what game), if it can dump my carts or dump/restore their savedata, if it supports savedata on slot 2, or ntrboot support.
