A few days ago, I downloaded Advance Wars dark conflict to see how it was, when I tried to run the game, at the title screen where it normally says 'Nintendo' it said 'Unable to write data. Switch off the DS and reinsert the Game Card' at first I thought it must be something wrong with the ROM file, but I tried it on No$gba and it worked perfectly, I later discovered that this was not only happening to this game, but to every game on my flash cart! Which was very strange seeing as it had worked perfectly the same morning. So I updated my firmware to 2.9...same problem I thought it might be the save battery on the flash cart which had got weak, so I charged my DS with the flash cart in it...same problem It might have been the contacts on the card which had got dirty, so I cleaned them..same problem Then I did what was to me, a last resort, I formatted my flash cart...same problem So I thought since it got ruined after I put advance wars on it, maybe it was the ROM file which had corrupted it, so I removed that...same problem! Now I am all out of options and unable to run any games on my G6 Does anyone know what the problem is, and does anyone know how to fix it, or am I left with a broken flash cart?
