The TV-boy type systems basically consist of a single chip VCS and
a large ROM for the games. If you ever find out who makes this chip
and how to order from them, you could save the design work for the FPGA.

AFAIK Game Boys only have a resolution of 160 x 144, which isn't enough
for the VCS. The Nomad is supposed to have a resolution of 160 x 200
and I think Kevin Horton posted some information about modifying it
on the Gametech list about two years ago. The Nomad seems to be easy to
modify, since the Genesis part is on an extra board, connected only
by a 30 pin connector to the I/O parts of the Nomad. The biggest
problem with turning the Nomad into a portable VCS seems to be that
the Nomad's screen requires RGB input, while the TIA only generates
composite output.
