This kernel, besides not working with my flashcart, actually bricked it. Everytime I tried using it. I have an R4i Ultra (r4ultra.com), which is an Acekard 2i clone. The best kernel it currently has is the AKAIO 1.8.6a one. It has some compatibility issues and the developer @Normmatt simply puts some code to make it incompatible with clones (which I question why since it doesn't even work with the latest DSi firmware anymore, there isn't even an acekard website anymore, we just achieved .nds loading on the 3DS without a flashcart, and I highly doubt they produce the Acekard 2i or its clones anymore). So, I came across this thread hoping that I would improve my flashcart's compatibility and installed the matching kernel for my flashcart. I tried running Pokémon Black 2 to test the AP patch, with no luck. It even made the game run way slower than with AKAIO! To my suprise, after I rebooted the DS, the flashcart was bricked. No "Nintendo" logo on the DS splash screen. Black icon on a CFW 3DS. It was dead. Luckily, I had a second DS, so I just used the ak2i bootloader updater to unbrick the cart, so it's working fine again. I tried running another ROM using the thiread's kernel, and it bricked again, so I just gave up. Unless @Normmatt decides to make a new AKAIO version for this clone (which, mind you, was made by the ACEKARD team), I'm stuck with the older version with limited compatibility.
