Alek has received word from homebrew developer Dark_AleX that custom firmware 4.00 M33 will likely be released by the tail end of this week. The firmware will include several internal changes, complete with an utility - primarily geared towards shell developers - for compressing PRX modules and PBP format files.
Additionally, the in-XMB recovery and savestate features outlined by Mathieulh last week will likely not be included in the initial 4.00 M33 release, but rather in a separate update.
The in-XMB recovery will feature multi-language support, allowing users to easily translate text strings into their native language without the need of hex editing files.
