Supercard SD (for GBA) • L+R+A+Select shortcut don't work to enter the SC Normal Save (Saver Serve)

[MBJ99]

I followed the guide who is on the Attach file for help me, but this didn't work, i still have some problemas to access the SC Normal Save, the same goes to SC Real Time Save, the only shortcut who works well is the L+R+Start+Select to return to menu.

Anyone can help me with this?
