Today DeViL303 releasedRelease Notes:
Here is a beta of a simple little XMB mod that allows the user to switch between 5 pre prepared boot_plugins.txt files. To install it initially, Simply copy the 2 category network xmls to dev_blind/vsh/resource/explore/xml/ and then install the tiny package. Then you can place your 5 boot_plugins.txt files into the "boot_plugin_x" folders which you will find at dev_hdd0/game/BOOTPGTSW/USRDIR/ (one txt file in each folder). Now this went from the idea stage to completed in just a few hours last night, getting the PVR set up and uploading the video took most of that time. :) I knows its a bit crude but it does the job. If you want to you can edit the xml file so it says which plugins are included in each "slot" like I have done in the screen shots/video.
The main weak point in this mod is that it always requires wMM to be running for its web commands which are used to swap the files. So if you install a boot_plugins.txt file without webMAN mod contained in it, none of the options will work and you will have to add wMM again manually. (unless you are on Rebug and running webMAN mod from dev_flash via the toolbox toggle, then you are fine)
Maybe someday we will be able to use a different system plugin for file manipulation, that way mods like this could be made webMAN Mod independent and Cobra independent, Also it would speed things up as the browser slows it down and makes it a bit clunky, would be nice and clean if it could use another plugin.
Thanks to @Berion for the icons and @aldostools for the great features of webMAN MOD.
