Dark_Alex gives advice on decompressing topmenu_plugin
In his release thread for 3.03/3.10 OE mix for UP DAX shared some ideas on decompressing newer topmenu_plugins:
If in this month which i will be outside, no one discovers what's going on with the topmenu of 3.10, i will research it.
My advice for reverse engeneers is to start searching for the decompression function in paf.prx. The assembler code is probably more or less similar to the one of UtilsForKernel_7DD07271. (hint: li at, 0x80808080), and then sniffing the functions to get the input and output buffers.
the function at address 00176FB0 of paf seems the candidate.
Thought this may be usefull.
