NetYaroze Access Card Reversed, PrometheOS for Xenium, Beta Switch Menus Discovered - ModChat 116

Getting two episodes in this month! First of all covering a project related to the Wii which is a Wii Shop revival service. Going back to the PSP, this covers the Kirk ROM being dumped, which is the console’s encryption/decryption engine. The original PlayStation gets some love, in the form of the NetYaroze’s Access Card being reverse engineered! Xenium modchip owners can celebrate a new development with the release of PrometheOS, a free and open-source replacement operating system for the chip itself. There’s many ways to dump GBA games, but have you ever thought a GBA game could dump itself through a crash? Finally, we get some awesome looking screenshots we haven’t seen before of an early prototype of the Switch System Menu!
