I am on tb cfw because is the only cfw which all my reactpsn stuff works perfect (I don't like rebug). Very stable and never had problems whith any program or game (tb or not).
I think the tb was never fully cracked. Only the eboots were cracked and dumped.
There are still things that are a mystery for me about TB.
What exploit used to load the dongle payload?
What modified files loads the dongle over the cfw tb?
How the tb team extracted the original eboots?
If we remove the drm idea, i think tb was a good piece of hardware.
