Takayama Fumihiko has updated his site again, this time with a fullscreen version of UNesterDC 3.0t5-pre6 , this is a test version only, so it’s far from perfect. This is what he had to say about it:

“This is compiled with fullscreen support, but cut statesave menus. You must be sure this is technology preview, I highly recommend using normal 3.0t5-pre6 if you only want to play NES games.”

You can get nesterdc-3.0t5-pre6-fullscreen-1ST_READ.BIN.zip (compiled with no-precision-emulate, no-draw-fps, no-statesave) from Tekezo’s site

Big thanks to dc^dude for the news.
