The shop contacted me again telling me the board with it's pertaining parts(not including the 3-D printed material for accessibility) would cost around 55.00 USD; and with the extra 3-D fitting pieces for a perfect looking assembly another 10 USD.

65 USD, not bad…and they told me I could get an RGBHV(VGA) signal through it; however the signal would be either 480i or p only depending on the game(luckily my VLP-VW10HT can read both)…they suggested if I wanted to force the signal to always be in progressive, I'd need a "Homebrew" hack, something like that…

I'm still interested in building my own, maybe I can copy the one I get ^^
