That is the most progress I have heard so far. Try to get lego indiana jones to boot. If you can boot that you may be able to force your way to data management by filing your wii memory with save games from various games. That would allow you to install the hacked save file. There is a link in this guide to more info on the data management trick, but first you must be able to play lego indiana.
Any luck with any autoboot cd's?
