Newbie here, please be kind. I recently purchased a flashcart, which is R4iSDHC DualCore 2017 to play NDS games. I downloaded the kernel (R4i-V3.9b English) from the site it said on the box (www.r4isdhc.com) and it said that it only supported until firmware 11.3.0. True enough, when I startup the slot-1 on my home menu, all I get is a black screen (My emuNAND is already on the latest version, so I can access eShop). However, I also read somewhere that flashcarts which support firmwares >7 will continue to work on 11.4. I followed the link to that, and was surprised to see the kernel of an even lower version that the one I already had, and was last updated in 2015. If I remove the microsd card (so I boot up sysNAND, which is of a lower firmware, ~9), the flashcart works. I guess what I'm asking is, apart from removing the microsd card whenever I want to play NDS games, what can I do? Is there some version of the kernel somewhere that will enable it to work even on the latest firmware?
