Its a simple fix to make it play full speed and full screen, although you may be playing on a LCD and it probably doesn't matter.
As above, both work great - I have a Darksoft version, very nice it is too.
Have you checked the back of your TV, most uk televisions of that era had a scart socket, if you want to run arcade boards you need one.
As above that scart to phono adaptor you have will not work.
Alternatively it’s a simple mod to swap the speaker connections around, your cab is stereo the 1C is mono. On my multi slot cab I fitted a switch, to switch between MVS and Jamma.
Like this. https://www.ukvac.com/forum/threads/jamma-mvs-mono-stereo-switch.59070/
I managed to fit a Hantarex 21 inch monitor in a UK wooden Neo Geo cab, stock monitor was 19inch… I think. But I defiantly went up a size and all good.
Good luck, it’s going to be a tight fit for sure, those big monitors are heavy.
I may have cracked it.

Not having much luck with this, did anyone try using the Teyleton FT232H above, mine shows no sign of life and unable to see anything on the 161 board.
Presume the Teyleton is dead on arrival so ordered another.
