OK guys, the problem on the Jornada 525 is due to the 256-color limitation and Mame CE is not an exception (also Metallion, Media Player 7, Zio Golf 2). There are 2 solutions. Either someone compiles a new 256 dithered gx.dll or Techmaster fixes this directly in the MameCE code. For example the last solution was followed for the game Snails and the results were excellent! Please Techmaster do something! The 525 users are many and still growing!

Yes pls to do something about this!
