@invzim it has arrived ! i updated the firmware (didnt know which ver was on there?) and tested with a super famicom. needed to use a sync stripper to get it to work with the default ini file - to be expected.
I was wondering, do you have a detailed howto on all the settings available in the ini file ? Am I able to use the button B (or any spare button) for useful stuff like switching between arcade RGB or SYNC so that I dont need to modify the ini file all the time ?
I think I will stick with using one of
@Frank_fjs 's sync booster with sync stripper for now and leave it in arcade mode. I will test this later on my NNC 29" CRT, my aim is to use this Retro Scaler A1 as a universal means of connecting anything (except an arcade PCB) to my Astro cab w/ NNC monitor.
SO far the picture is amazing, just on broadcast Sony LCD monitor, will test more later on. Thanks for the super fast service
now I can get back to grinding Zelda1 runs out.
