How to multiply resolution?

Hello, everyone.

I'm trying to configure MAME to quadruple the source resolution of my Fairchild Channel F games, so the CRT filter looks right (the original console did this). I can't seem to get it to happen, though.

What's the right way to accomplish this?

The channelf driver is currently outputting a video resolution of 102x58 which is not correct. The actual hardware duplicates pixels on the x-axis and repeats each scanline 4 times (5 for PAL) in the y-axis to produce an output of 204x232.

The emulation needs updating to produce the correct resolution.

Should I file a bug ticket?

Yes, it should be logged as a bug, though there's a chance I may have time to look at it before next release.
