main.c
add line extern void kernel_ent(u32 Temp);
and write Kernel access in a function
use kernel_ent((u32) &your_function) to call it

// -------------------------------------------
// Kernel access under FW2.50/2.60 VSH
// use Noobz's eLoader(TIFF) 0.9.8
// -------------------------------------------
// Game mode Kernel access by hitchhikr / Neural.
// VSH mode Kernel access by moonlight
// Mod. by 0okm
// -------------------------------------------
