Syscall index: 0x1E63
Function signature: void LoadVRAM_1(void)
Loads the previously saved VRAM data back from the address pointed to by GetSecondaryVramAddress. Use SaveVRAM_1 to save the VRAM.
Since the process of switching from the Main Menu back into the running app calls this function, you won't be able to restore your VRAM contents when the Main Menu is opened. If you call this syscall after the Main process has overwritten the SaveVRAM_1 buffer, nothing will be restored (there appears to be some intelligence controlling whether the buffer has been modified since your last call to SaveVRAM_1).
