If you're getting it with 'newer' games then perhaps the global setting for AAP is not enabled.
Tested it at default, on and off. Didn't make any difference.

Also try using a different SD card if possible as a control. Some SD cards can cause problems. Since you and your friend are at least in the same place you should have done a few test to establish where the failure is.
Been there. Done that. Tried different SDs and different SD readers (Micro to USB and Micro to SD).

I'm going to assume you both have Acekard 2i's, so that they are interchangeable between your DSLite and the DSiXL
You assumed right.
QUOTE
1) You confirm that your Acekard2i and SD card can play the games you describe
2) Place YOUR Acekard2i with YOUR SD card into his DSiXL. Test
3) Take above config test on DSiXL
4) Take HIS Acekard2i with HIS SD card, place into your DSLite. Test
5) Take above config test on DSiXL
6) Put YOUR SD card into HIS Acekard2i. Place into the DSLite. Test
7) Take above config and test on DSiXL.
8) Put HIS SD card into YOUR Acekard2i. Test on DSLite
9) Take above config and test on DSiXL
By systematically going through the various configs with your Acekard, DSLite and SD card as control, you should be able to determine where the issue lies. I suspect it's probably a bad SD card on his end and he'll have to get a new one most likely. But try the above and see what happens.
