VitaMips is a sample homebrew that demonstrates how to integrate the MIPS processor into homebrews without the need of a kernel plugin. This capability is beneficial for PS1, PS2 and N64 emulators.

pcbctool

This tool generates a bootcode that can be placed at PSP memory 0x88600000 and executed with sceCompatStart().

Enable PspEmu Capability

To enable PspEmu Capability in homebrews, you need to use 0x2800000000000013 flags in your fself.

Fake PSP license

Thanks to the patch rif_check_psp_patched in taiHEN, it is possible to load fake licenses. A license is required in order for sceCompatStart to succeed.

sceCompat API

The API for PSP compatibility is available at compat.h.

TODO

Currently, 64MB of CDRAM is allocated by sceCompat. We don't need that much memory.
Implement MIPS baremetal code for interrupt handling.
Implement sceKermit code, such that we can use sceCompatWaitIntr, sceCompatInterrupt, sceCompatWaitAndGetRequest and sceCompatReturnValueEx.
