Neo Geo on Dingoo Question…

Please read everything before flaming me.

Here’s my problem. I have downloaded the rom for the Neo Geo game Waku Waku 7 multiple times from multiple sources along with other Neo Geo games to test the emulator on the Dingoo. Had no conversion problems with this game ( did with some others, but found that those games where known to have conversion problems ) and moved it onto my Dingoo. Every time I run a Neo Geo game on the Dingoo the graphics look jumbled and undistiguishable, however text shows up fine. The start up NEO GEO sign is correct but any images after that, other than plain text, are not. I have tried deleting the emulator the system came with and installing a downloaded copy of it in its place. Same problem. I seeked out and found a newer Neo Geo emulator that claims to work on the Dingoo and tried it, but with the same results. see http://www.mediafire.com/?3neywlgjjnn if you want to see the second emulator. I would think my hardware is bad but everything else in the system runs as good as expected. For example the CPS2 roms look great with the normal slowdown in game play speed. I have seen no one else complain of this issue, so now I am asking for help.
