It goes as it says.

Code:

D:\PSP\PSP Updates\3.73-official dump\F0\kd>prxtool -o ge.idc ge.prx
Loading ge.prx
Assertion failed: m_pElfSections != NULL, file ProcessElf.C, line 414

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

PRXes are decrypted ELFs, no problem here. IDA loads them more or less ok.

Here's the output with -d flag set:

Code:

Have you tried rebuilding prxtool from source? There was a change to work with newer prxes at some point.

I've grabbed latest prxtool sources and has successfully built it for win32. There's one minor problem with tinyxml sources in tinyxml.cpp:

Code:

./tinyxml/tinyxml.cpp: In member function `TiXmlElement* TiXmlNode::FirstChildElement()':
./tinyxml/tinyxml.cpp:487: error: expected `)' before ';' token
./tinyxml/tinyxml.cpp:488: error: expected `;' before ')' token

Someone who has access to svn, please remove extra semicolon there. :-)

There's no extra semicolon on line 487... http://svn.pspdev.org/blame.php?repname=psp&path=%2Ftrunk%2Fprxtool%2Ftinyxml%2Ftinyxml.cpp&rev=0&sc=0 You must have gotten a corrupted copy or something.
