Can't get Kof2k2 and Rotd to work on Kawa-x Plus

[SF2MJ]

I renamed the rom files on both games, zipped them up, changed the name of the zip file like the tutorial for Kawa-x plus stated.

Then dumped the roms into my roms folder on my xbox HDD.

But the games don't even show up on the Kawa-x Plus neogeo games list. The only games i have running are Matremilee, metal slug 4 and CVS Chaos.

Can anybody help me with rotd and kof2k2?.

Thanks

make sure you zipped the roms and not the roms in a folder also make sure that you grabed the decrypted set of thoses roms
