Hacking Pokemon Black and Black 2 crash on R4 Dual-Core 2017

[MAFLP]

Hi, I'm trying to play both Pokemon Black and Black 2 but I'm always getting the same problem: Freezes during battle or out of nowhere. I've tried with the AP patch on and off in the cheats and also patched the games and even changed to YSMenu but no luck. What can I do? My R4 is the Dual-core 2017 version (the white one) and i'm using a DSi XL with 1.4.5U
