Where can I find instructions?
Instructions can be found here. These will be improved over time so please check back.
When will the next batch be ready?
Unknown. I'm researching new ways to sell the product so production is paused for now. E-mail email@example.com if you're interested though and I'll let you know when they become available again.
Can I use with RGB SCART (Framemeister/OSSC or similar)?
Yes. LightGunVerter has a composite sync input for use with RGB SCART. There will be a SCART breakout board available in the future. E-mail firstname.lastname@example.org if you are interested.
