The simplest way of installing the MC Exploit has to be using a AR MAX or AR EVO disc... if you know someone that has either one and a USB storage device (including some MP3 palyers and Digital cameras) you can find the MC Exploit online and copy it to the USB Device and then use the AR MAX/ or EVO disc to install to memory card....
any customization that you may want can be achieved with a few tools... live SaveBuilder (extract and create MC saves), BMP2Icon (make custom save file icons), and your favorite text editor... remove any files you won't need... patch any that you need patched.. and add a few toys.. I mean tools to the setup....
and if you ever get a router... you can do a lot of nifty things using the FTP.... although I'm not sure a router is needed.
