theres not going to be one unless theres a way to install trucha on IOS53 and the system menu.
I had an idea about using bannerbomb to run dop ios and fix it.....but theres risk of a brick and so bootmii would have to be used also. If you do all that, might as well go all the way with HBC
For me, i finally tried and bootmii refused to install either way....even with the guide.
Maybe one day someone will fix a disc that would instead of updating to 4.1, would instead give us what we need.....but that probally will never happen.
once the iso is changed, its not an official nintendo disc anymore and is of no use for chip users.
Me personally, Im waiting to buy a new chip.......Im sure one will be availabe with the fix by the first of the year. enjoy the games youve got
