error 0x80020148 when starting homebrew

[sauron_le_noir]

I try to port a Nintendo DS emulator to the psp it compile now without error
generating a EBOOT.BPB but when starting the emulator i've got this
0x80020148 ----> ,unsupportedPRXtype
My psp is a slim running CF4.01M33-2

here is my makefile

Make sure you main file has the module info/et all set for a user-mode prx, like this

Code: Select all

PSP_MODULE_INFO("MyProgram", 0, PSP_VERS, PSP_REVS);
PSP_MAIN_THREAD_ATTR(PSP_THREAD_ATTR_USER);
PSP_HEAP_SIZE_KB(-256);

You don't need to create a user thread - you ARE a user thread. Remove that code. That code was clearly from a project that used to run in kernel mode, so I'd guess the error is due to some other kernel-mode function still in the code. One common one you saw in a lot of older apps set the general exception vector to trap crashes. That doesn't work in 3.xx/4.xx without a special kernel-mode prx. If you look at the dosbox thread, you'll find such a prx if you want exception trapping in your app.
