The mod currently using the original composite as sync apparently, but has similar sync options to Voultar's (ttl sync, 75 ohm sync, etc). Can you confirm if the gscartsw_lite will likely play nicely with the sync coming from the composite video output of the Duo, or might require the tweaking as suggested above (ttl, 75 ohm sync, etc)?



Asking so I don't have to arrange for it to be delivered, then discover the gscartsw_lite might not work with it, then have to send it away for additional work. I appreciate you might have to make an educated guess on this if unfamiliar with Borti's stuff.

So far it seems only Voultar's mod is confirmed working?



Has anyone else had any success with other mods/cables?



My Duo-R has a VERY old resister mod, so it's being sent for an upgrade using this:

I sent the guy my gscart unit for testing as well. Is there anything to watch out for?
