I don't think Ben 10 Alien Force Vilgax Attacks has anti-piracy actually....
Update your flashcart's firmware to the latest one too.

What cart are you using and on what console?i have mario+sonic the winter ol games and kingdom hearts and they both work.on r4i v1.4 unsure about zelda ill try it now

They all work fine on my r4i v1.4 with firmware v1.2b make sure you get the right ben 10 rom though 4410 is the eu one and it works fine but the 4321 usa rom version doesnt open properly with winrar and comes up with an error while unzipping.

there is nothing wrong with our roms, it is your emulator or flashcart at fault. If winrar cannot open a file then it either got corrupted during download or your version of winrar is out of date.lachy0192: please refrain from using shortend words such as 'any1' and 'r'. Write full English words as per our rules.

loonylion you're wrong. There are problems with your roms but some might not realize it. The sooner you do the sooner you'll stop spreading false facts. And for the person who is having game problems here are some links for the cracked versions so you can just download and put it on your flashcarthttp://www.4shared.com/file/169222158/7f06d4a7/4162_-_Mario_and_Luigi_Bowsers.html Mario and Luigi Bowsers Inside Storyhttp://www.4shared.com/file/166805010/a4b7cbf0/4506_-_The_Legend_of_Zelda_Spi.html Legend of Zelda Spirit Trackshttp://www.filefactory.com/file/a1h15a3/n/Kingdom_Hearts_358-2_Days.nds Kingdom Hearts 358-2 DaysEnjoy
