void* alloc(size_t size, int unk)	unk is possibly pool? PSGroove uses 0x27.	0x62088	0x61CF0	0x61CEC	0x5DF4C	0x59D54
void dealloc(void* ptr, int unk)	unk is possibly pool? Should be the same value of unk given to alloc.	0x624C8	0x62138	0x62134	0x5E38C	0x5A194
void process_utils::create_initial_system_process().	Called to start the first userspace process, which is normally "sys_init_osd.self" but it can also launch recovery mode or update mode.	0x287D50	0x287858
void Panic(int unk)	This function does not return. (It seems that the offset point to a location that will cause panic after, not the real panic function, use with caution)	0x288568
