BootMii Configuration Editor llows you to change the values in the /bootmii/bootmii.ini file without having to take out the SD card and edit it on a PC.

Changes:

– Automatic download/updating of application when a new version is released
– Additional option in the settings menu (accessed via the ‘home’ button). This option allows to enable/disable the automatic update/version checking and is particularly useful if you run this on a wii without an internet connection
– Settings File paths are now resolved from the argv/argc parameters when supplied from the loader (N.B. the homebrew channel does provide these). If not supplied then a default location of ‘SD:/apps/Bootmii_cfg_ed‘ is assumed
