It's been a couple of months since we've heard from Weltall (his last release was back in early June), so now's about ripe time for another update for CWCheat. Released just today is version 0.2.2 REV.D.
For this release, Weltall's optimized his cheating tool to reduce the binaries it uses. Some fixes were also done in the firmware version check process that the PSP goes through. Here's the full changelog for CWCheat v0.2.2 REV.D:
* [ALL] Now > 4.x firmwares are checked for the sony msfatmod thread suspend bug and the check of the memory stick space is disabled to avoid a freeze situation.
* [ALL] Optimizations in the firmware checking
* [ALL] Added support in the gui for setting a button combination to open the text reader directly
* [ALL] Added the possibility to have cwcheat look after a certain adress and show changes happening to it (you can access it from the cheat search menu)
* [ALL] Updated the pointer searcher to allow use from the command line. These are the arguments it takes in order to use it this way:
o cli
* [ALL] updated the toolchain to the latest version
* [ALL] Various optimizations which allowed to reduce the size of the binary
The download archive includes some relevant documents to go through; there's a readme and a detailed FAQ in there, so make sure you understand everything.
