- To override the last used boot mode on soft reboot, you only need to press A if you want to boot to the default option. Holding L(+payload button)/R is enough for the other modes. - Added version number to the config menu - Replaced the memsearch algorithm with a faster one - Integrated 3ds_injector from @yifanlu. This brings us region free and all the other FreeMultiPatcher patches. Other than that, you now have the possibility to display the currently booted NAND/FIRM in System Settings! - Rewritten most code for the config menu. You now can navigate to the first/last options with left and right. - You can now choose the 9.0 FIRM to be default in the config menu. This will essentially switch "no buttons" and L in both modes. - You can now choose the second emuNAND to be default in the config menu. This will essentially switch "B is not pressed" and "B is pressed". - When the second emuNAND is booted, it will persist like the other boot options on soft reboot - Bugfixes
