Using the DSi hacking guide. dsiguide.me After the downgrade worked in NO$GBA, I flashed my nand back to the DSi, and then got to work on injecting Sudokuhax. I ripped my legit-purchased sudoku app from my 3DS, patched it using Lunar IPS, trimmed the ticket, and put them into the nand, tested in NO$GBA again, and tested out Sudokuhax. Launching Sudoku opened the game, i clicked to simulate a tap, and it crashed the emulator like it should. So after confirming that it worked, I flashed the new nand copy to the DSi once more, and now I can launch SRLoader from Sudoku. Eagerly awaiting HiyaCFW and RocketLauncher now (if they ever come out... OP made the RocketLauncher announcement thread in July.)
