echofreeze: While I have and enjoy a framemeister, nowadays it’s not the most cost effective solution. I recommend using a retrotink2x or RAD2x. The best bang for your buck is going to be the retrotink2x. Check out the stats, https://www.retrotink.com/product-page/retrotink-2x
If you are looking to get a framemeister then it should be interlaced support, e.g. 480i. Although, you may want to review the GBS8200 with GBS Control https://github.com/ramapcsx2/gbs-control or wait for the OSSC Pro for a cheaper interlaced solution.
