Finally i got around to doing this. Very easy actually.
So u know the routine RTFM!!!
the read me says
Code:
Custom xmbWave Packager v0.1 for MAC!!
------------------------------
zpipe by zlib crew
orignally found by DarkStone
applescript by a_noob
Instructions for use
------------------------------
1. make sure this folder is on your desktop (it has to be exactly named XMBWave [case sensitive])
2. Open system_plugin_bg_deflate.bin in a hex editor.
3. Edit the lines u feel neccasarry (look at vulpix's post for more info)
4. Save this file.
5. Double Click xmbWaves click compile then run.
6. Put the file in /vsh/resource/
7. Done!
and i think ill add some screenies... WAIT there are none to be seen

just run the script and its done.
for the terminal junkies out there u can just navigate to the dir and run
Code:
cd ~/Desktop/xmbWave
rm system_plugin_bg.rco
rm system_plugin_bg_part2.bin
cp system_plugin_bg_part1.bin part1.temp
cp system_plugin_bg_part3.bin part3.temp
./zpipe < system_plugin_bg_deflate.bin > system_plugin_bg_part2.bin
cat system_plugin_bg_part3.bin >> system_plugin_bg_part2.bin
cat system_plugin_bg_part2.bin >> system_plugin_bg_part1.bin
cat system_plugin_bg_part1.bin >> system_plugin_bg.rco
rm system_plugin_bg_part1.bin
rm system_plugin_bg_part3.bin
cp part1.temp system_plugin_bg_part1.bin
cp part3.temp system_plugin_bg_part3.bin
rm part1.temp
rm part3.temp
I think i might add a GUI later or make it a automater task or a sh. But u can do it simply just run that code using zpipe included.
So rock on and tell me what needs to be done / what can be changed or what you would like
