RGB modded Snes mini, plan to use with GBS 8200, need advice

[PC-ENGINE HELL]

Posted this on the Sega 16 forums also, but figured I would hit this forum up also since the GBS is probably used by more people here then Sega 16. I RGB modded my Snes mini here. RGB is tapped off of the encoder chip, as is sync, which was pulled off of pin 7. I wont be using the Snes AV out port, as I opted to do output jacks for each signal so I can make my own cable when the GBS arrives after I ordered one. Was planning to order a GBS 8200, and was trying to find out in advance if this combo will work fine first. I have read issues about the GBS having issues with different Jamma boards and game systems sync output, so figured I should ask. Is the GBS fine with flat out sync output though from the Snes mini, and if not, what extra work needs to be done to make them work together?

Also, this is what I did as far as tapping RGB and sync goes:
