Final Fantasy TA2 wont work :(

hey guys, this is the second DS game I'm playing (the other was pokemon pearl and it worked fine)So I was thinking the game was fine... untill after I finish the 3rd mission and then try to save/check unit stats (both screens go black while music is still playing) or I enter the pub (in this case only the bottom screen goes black but still unplayable). I've tried completing this mission over and over again like 10 times and the result just stay the same..I'm running it on no$gba 2.6a with the no$zoomer with the correct save settings (it saves fine before completing the 3rd mission). I also tried doing what says in the common issues

I'm stuck in a game, and there's no way to get past it.
Which probably means that there is some form of anti-piracy protection on the ROM. Recently companies such as Square Enix have been implementing these piracy additions from the added on functions in the Nitro SDK.
EMULATOR: Find the code and import the code in the emulator options, press F2 or Utility->Cheats tab in no$gba for the cheats menu. If you want to find the code from a database from the GBAtemp Cheat Database for example, use R4CCE by Yasu to open it, find the game entry, and copy the code/s. Otherwise use a program such as DSATM to patch the ROM with the Action Replay code

Being this a square-enix game I suspect this might be the reason why it happens so I found the code ( Final Fantasy Tactics A2: Grimoire of the Rift (U) {A6FE 1EBED497}) and created the cheat file but even after enabling it, the problem persists.Can anyone please help me ?

Try using the full package of no$gba.
Not sure if the game has an AP issue with emulators, but I managed to finished it using the previous version, 2.6(on my first game),
as well on 2.6a(on my second 2nd attempt on the game).

YEAH it worked! thx :D
