Did you actually try to activate the AP bypass???
Shinigami357's easy as all hell step-by-step guide to the AKAIO AP Bypass:
1. Boot up your DS
2. Select your Acekard
3. Scroll down the games' list and highlight the game you wish to play
4. Press Y twice; a GUI with some options will appear
5. Scroll to the bottom one which says "Bypass AntiPiracy" and change the option to "Enable"
6. Press A twice
7. Start the game
8. Enjoy!
9. Tell every AKAIO user you know how to do it properly
Hope this helps
Disclaimer: It has been observed that in some cases certain issues prevent slower micro-SD cards from using the AP Bypass altogether.
