I just got the RCMLoader and I want to boot into lakka from it, it's enough when I copy "cbfs.bin" and "coreboot.rom" into the USER1 folder on the RCMLoader and just rename "cbfs.bin" into "payload.bin"?
right i remember sorry my last post was trashI believe to launch Lakka you must use Hekate and go to Launch > More Options. I don't think you push the cbfs.bin as a payload.
