Hmmmm Well, it appears something is up with the rom I couldn't figure how to remove the lines as they appeared on mine as well along with black outline blocks in the sky
Tried everything in Jabo's D3D8 and 6 to try to alleviate the problem even fooled with a Beta DX9 Graphic Plugin to no avail to remove the lines.
I think the PJ64 Squad should have a looksee at Mega Man 64 and see if it shows up for them.
As for right now I'm at a loss...:borg:
