Miyu has modified the previous patch for the GP2x firmware to reduce the writes to your NAND. This will increase the lifetime of your GP2x. Here are details:
It has now been optimized for Firmware 1.2.1 and you now have the possibility to either install the cleaned bootscripts, ext2 support for SD-Cards AND the NAND lock or only the Bootscripts, the ext2 support but not the NAND lock.
WARNING: This is something for people who know what they are doing. Keep in mind that doing something wrong can brick your GP2x easily. Also keep in mind to uninstall this patch, before upgrading to a newer firmware.
