Outputing video to 2 displays

Unread post by bugwhacker »

Lets talk about 2 display systems where the 2 screens have differant data going to them.

I am talking about the Nintendo VS. System or Tysons Punch-Out.

Since we already run super-resolutions to enable 240p over the hdmi port into a hdmi-rgb convertor , it should be doable to use a 1x2 video wall processor in between to split the hdmi super-resolution into 2 normal resolution screens that are encoded as player 1 screen and player 2 screen.

I dont know if the Mister has the horsepower to actually run as a VS system or even Punch-Out but it does seem this may be a path to enable the video portion.

The video wall processors have gotten very reasonable and can be picked up for $100 , add 2 hdmi-rgb convertors for crt's or just run 2 lcds.

Take a look at the 2P GB core - has the option to output different screens to DE-15/HDMI.

Nope, not GB core. The GBA core can do that. The GB core only displays double on one screen.
