Ah, that is indeed a known problem. Try this:
1. Start up No$gba. It will give the message. Go to Utility > Cheats.
2. Click the 'add new' button on the bottom left.
3. Click 'Action replay DS' and paste this code:
52004EA0 E8BD01F002004EA0 EAFFF25CE2001800 0000005CE92D4008 E3A00000E3A0150E E2811A06E5810B44 EA5FE9F2E59F4034 E59F5034E5845000 E59F4020E5945000 E59F601CE1550006 03A0500105C4500A 03A05000E1445DB4 E8BD01F0EA000D95 021809E028AAFF1F 037FBFE0EAA01606 00000000D0000000 00000000
And click OK.
