## AHBProt
AHBProt stands for Advanced Hardware Bus Protection. AHB is what connects all the Hardware Devices of the Wii to the PPC. Its protected to keep hackers from easily gaining access to these devices. But there's an easy way to enable access to the AHB by setting bit 0 of the access rights field in the TMD. The HBC and other channels/forwarders do this by setting offset 0x1DB of their TMD to 0x03. They also set offset 0x18B to 0x3A (58) to use IOS58.
