Blackaddr released a new version of the Xbox 360 SMC I/O Config Utility - a simple utility to reconfigure output pins on the SMC that are used to execute the JTAG transaction to the GPU. It is used to research and fix problems caused by sharing SMC output pins, or caused by the bit timing of the JTAG data.
What's new/fixed:
* Linux version is now included. Compiled with G++ on Ubuntu.
* This version has very minor updates. I've added an interactive mode for those who like multiple choice. This is to be more newbie-friendly.
* The program now supports modifying SMC files that have already had the I/O changed, so you don't need to keep feeding it the original when testing different configurations.
