GBA V. another GBA problem blank screen help

[Designer noob]

So, I just finished wiring my GBA cartlidge and I inserted a GB color game, which was pokemon yellow and it worked. Then, I inserted a dragonball z game which, was a GBA game and it worked. I then inserted the game Final Fantasy advance and it loads goes past the Gameboy nintendo logo and then the screen goes blank.

WHY??????????

lol, there better be a fix. Thats the only reason I did a GBA with N64.

Edit: A few minutes later: I placed my game in another gameboy advance and it worked? Whats up with that?

Blow on it and re-insert it.

[Designer noob]

already tried that

take a Q-tip or cotton swab, add a bit of rubbing alcohol and clean the contacts a little bit lol just make sure that it drys completly before putting the game back into the gameboy

[Designer noob]

I don't see how that would help. It works in one gameboy advance and not another. Meaning if it works in one the cartridge can't be dirty in any form.

looks like i misread something
i don't know then :/

[chainfire95]

did you try other GBA games in the GBA?

[Designer noob]

Yes, other games work. But, that one seems to not want to work.

[Diminuendo]

maybe FFA uses traces not used by every game and they haven't been wired correctly

[Designer noob]

Is there a guide or something that tells you what pins each of the game uses? So, I know which one is done incorrectly?

For what it's worth... I have a FFA cartridge which works on a real GBA but not on my DS, and it has a similar behavior on the DS. But I believe it is a pirate cart. Perhaps it's the same pirate cart and the errors are related?
