Homebrew Need help on MAME2000 for Gamecube and Wii

[Gamecuber]

I have compiled MAME2000 core of RA for GC/Wii, and I found that there are some graphic glitches caused by resolution scale. I don't know how to fix it, could anybody tell me how to fix it?
Here are screenshots, the fonts and some tiles are not rightly showed.
