What files need to be in the sd card at all times?

just wondering' i mange to mod the wii' and have the installs i needed on the card' so do i need to leave:

trucha bug restorer
fireware updateder
etc' or can i remove em?

I also got on one of my channels:

gamma 0.3 with 002 fix' that i dont know what is that' lol

any info thanx'

You might like to keep the Apps folder with a Wad Manager folder inside and maybe keep a Wad folder in root for any future wad files you might like to install, but that's it.

And what is gamma 0.3 with 002 fix' for?

That is a backup loader to load disc copies of games you burned. More people use NeoGamma which is in revision 7 and so you will see it written as NeoGammaR7, some people are using uLoader now as well. All the programs are used to load backup discs.

If you installed a backup loader as a channel-you no longer need it on your SD card. You would have installed it using Wad Manager.

o.k thanx for the info'
