Title: XRGB-2+ Sync Issues
Post by: Shou on December 02, 2009, 06:45:22 PM
I've modded a Neo Geo Pocket Color and SwanCrystal for RGB output using an FPGA card but for the life of me cannot get it to sync with the XRGB-2+. I've used cSync and just the composite video (which does work) but the image is just rolling. Connected directly to my Sony PVM, there are no issues though. Any ideas would be appreciated.

You could try running the sync output through a LM1881 circuit...  ???  I don't have a RGB modded WS or NGP to try myself.
