Here is our unobtrusive and cheap famicom AV modd. Also gives an improved picture. The label might not be perfect , that's because I put it there.

A Pc Engine Ten No Koe 2 with RGB output. This beats the DIM contacts, because the Scart cable is a standard cable. Also beats modding your pc engine console.
A mod of SG 1000 II was shown further down on the page.

Also modding Saturn and Dreamcast consoles! But those consoles cost a lot to chip internationally.
