Nah, not a freak, different strokes for different folks.
On your artwork, I feel your pain. I too have elements in some of my bezels that aren't attributed because I don't recall where they come from. However, I never claim them as my own, and obviously just post stuff for free, so don't feel especially terrible about it. In fact, in many of my Bezels, I don't even credit MYSELF in the LAY files.
I'm sure the like of BK and Jason would be interested in at least seeing what you've created.
I have all the elements to make a Generic Mame bezel, I've just never found time to do it. Maybe I'll get to it soon.
On scanlines.... off-topic, but I've found them difficult to use. Not sure what I'm going incorrectly. What's the best you have?
