Mocha CFW par dimok est un custom firmware pour Wii U basé sur iosuhax qui est plus simple puisqu'il ne nécessite pas de fw.img sur la carte SD.
Mocha CFW s'accroche de lui même dans le processus de lancement IOS, juste avant de lancer le bootrom, et patche le ELF IOS en mémoire avec de nouvelles fonctions.
fixed bug with re-initialization of EEPROM and OTP dump on SD card
added new feature which allows you to disable os full relaunch (only possible in combination with sysNAND, not redNAND)
added new option which allows to return to HBL after executing the patches and not launch to System Menu (only in combination with disabled OS full relaunch)
changed name of application in config file to mocha
don't write to sd haxxdump info sector if read was a failure
fix bug in fsa read from sd on kernel
new default launch image (thx thaikhoa)
some clean ups
NOTE to the new feature:
The new feature to disable full OS reload behaves similar to the simple signature patcher except that it setups execution memory region from kernel for wupserver and iosuhax dev node code and starts those. So it's a fast simple signature patcher with the addition of wupserver and iosuhax dev node. Another addition to the simple sign patcher is that the patches reload themself when exiting settings. Launch image is disabled for this method though.
Several features can be activated or deactivated in the config menu. You can choose to skip the config menu on next launch in the config menu itself. If you lock yourself out you can just hold the B button on start to force enter the menu again.
The OTP and SEEPROM dump is automatically injected into SD card if it is missing when OTP or SEEPROM redirection is enabled in redNAND mode. You can not redirect SEEPROM or OTP on sysNAND mode. The WiiU drive key part of the SEEPROM is not redirected as this one has to match the console drive key. Otherwise the console will report and error and lock itself out. So an exception for that range of the SEEPROM was added.
You can also use the new version of the SDIO NAND Extractor/Injector (v1.2) to inject existing OTP / SEEPROM dumps into the SD card or dump the dumps from the SD card.
