It has a display resolution of about 100 x 60 pixels, and a colour palette that is a bit wierd. Those readers old enough to remember PC CGA games will get a sense of Deja Vu.
It does have nice controllers though.
The sound is a bit pathetic - only three tones - but you can do something with that, warbles and beeps.
So, is this the worst console ever ? Not even close.
(The Channel F is emulated by MESS and the majority of the cartridges have been dumped)
