Ithink it overwrites it, so when you reboot, the normal OS is there.

Yes, OSLauncher overwrites the original OS in RAM. The core functionality of OSLauncher boils down to five C statements, one of which may be superfluous:
Code: [Select]
   *((uint32_t *)0xDC00000C) = 0xFFFFFFFF;
    __builtin_memcpy((void *)0x10000000, dest, ziphdr.usize);
    __builtin_memcpy((void *)0x00000000, (void *)0x10000000, 0x40);
    *((uint32_t *)0xC000001C) &= ~((1 << 0) | (1 << 11));
    asm volatile(
    ".arm \n"
    "mov lr, pc\n"
    "ldr pc, =0x10000000\n"
    );
