I bought a flashcart and DS Lite off kijiji and put pokemon black onto the sd card. I got "load rom errcode=-4" So I went to this topic http://forum.romulation.net/index.php?topic=53474.0 And I installed YSMenu 6.51, then YSMenu v6.96. After that I tested it and nothing even happened on my DS Lite, has a sad face and wasn't working. So I put back the TTMenu stuff that was on the card before, and the old TTMenu came up, and I selected YSMenu(There was a bunch of YSMenu.nds files, i opened a random one), and it opened (replaced the menu with an uglier menu), but when I went to pokemon, same error message. After that I also tried putting on RetroGameFan DAT Update v6.95 6126, still got the same error message though. Any help would be great. Or if someone could upload everything on their SD card so I can just copy it. Been messing with this for far too long.
See if your pokemon black maybe patched are clean. Most of the fixes for DSTT are only for clean ROMs. The encrypted game ID in extinfo.dat and infolib.dat thats in the TTMenu folder , may not be supposted for the version of ROM you have . question is where you downloaded your game from. but first make sure its not a patched version.
