Fragmare, that'd be awesome. I definitely would feature them in the next Homebrew episode and I always like showing Turbo/PCE stuff. It seemed to be a fairly popular episode among the audience as well and it was really fun to make!
As far as the Retro Duo Portable goes, I think the BEST use for it is to take with you to thrift stores and flea markets/whatever to test out games before you buy them to see if they work. Just as long as said games work on the Retro Duo of course.
