Exception Handler for Kernel 3.71
---------------------------------
All credits goes to crazyc (for the prx code) and SamuraiX (sample usage code)
What is it?
-----------
exception.prx is a prx that handle exception and can be used
to show usefull information abuot a crash.
How to build:
-------------
To build exception.prx
$cd prx
$make
To build the test program:
$cd test
$make
How to use it:
--------------
Include utility/exception.h in your main.c and init the handler with:
initExceptionHandler();
Copy exception.prx in the same directory your EBOOT is.
Please check the test program. ;)
Note:
--> For Wagic, the code is already included in JGE's main.cpp. You just need to copy the prx with the EBOOT
