Dreamcast VGA

The Dreamcast VGA Box is an accessory for the Dreamcast, a video game console produced by Sega, that allows it to output to a computer monitor or a high-definition television (HDTV) set through a VGA connector in 480p, otherwise known as progressive scan.

[6][a] Though the VGA Box did not receive a release in Europe,[10][11] PAL consoles can use it since it has no regional lockout.

[14][15] Most third-party versions are functionally identical to Sega's model,[16][17] but some designs like Performance's add features such as VGA passthrough.

[15][18] Most Dreamcast games are compatible with the VGA Box so long as they display in 640×480; this applies to most 3D titles.

[19][24] Though a handful of sprite-based games supported VGA, most notably ones from Capcom, at least some, if not all of their sprites were originally designed for lower-resolution displays and may resultingly appear less detailed when displayed through VGA due to poor image scaling.
