Depends on what I'm trying to use. With WoodR4Launcher.rar, I see 3 icons with a black background. With R4CartLauncher_AnyKernel.rar, it's stuck in the Loading... screen. With MoonShell2_R4.rar, I see some error screen in english and japanese.
Discard Moonshell launcher, it's not useful for you.
Your twl_firm is correctly patched. Your problem seems to be your cart. Launch either of the launchers with the cart completely pushed with your in the slot and see the magic.
