Summary MESS-specific 08012: channelf (and clones?): Fairchild Channel F runs at wrong resolution
Description Pernod writes:

"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."

Steps To Reproduce Run any Channel F games. Issue becomes very apparent when using scanline effects.
