Hello icomp support!
Brand new card received and everything appears to be working out of the box except the following issues:
(i.) HDMI audio - sometimes no sound when starting a WHDload game. Reloading the game once or twice can fix the problem.
(ii.) Grafitti NTSC mode is not working?
When "DoomAttack AIO" is configured to use the Graffiti NTSC mode with the Graffiti C2P, the display shows the raw undecoded graphics. The IDV on-screen-overlay does show Graffiti mode detected. I note that changing the Workbench Overscan preferences can affect the degree of corruption. I note the following website saying it needs to be aligned to pixel boundaries divisible by 8 e.g. 0, 8, 16 etc. I have not been able to find a setting that works.

If configured to use Graffiti PAL mode, it works.
If I use the official Graffiti test viewer to view the test image, it does open the image of the cat in a PAL screenmode.
Is this a DoomAttack software issue or IDV firmware issue?
I do hope the NTSC issue can be resolved due to the higher framerate performance.
Thanks!
