yeah but as you can see thats 9.4 sysnand with the downgraded whitelist, so even if ds and gba mode still don't work in their new exploit you should still be able to flash the whitelist to sysnand and use the bluecard in sysnand, ofc you should always be careful doing anything in sysnand, i.e dont just flash random files, and only use files from trusted sources, and as always have a nand backup just incase anything goes wrong, but i personally tested that to make sure it all worked and had no side effects, and everything works as normal but DS flashcard where unblocked
anyway its there if anyone wants it, nobody is forced, but if you intend to use the blue card on a 9.x system it may be the only way to do so
