Thats cool, more curious about the horsepower of the PI 2. I posted this on another forum, you guys have any insight into this?
I was thinking of building a small emulation machine using one plus a JPac to use in my Blast City. Mainly to play some older console stuff and one off boards, like In the Hunt. Been doing some research and this is what I have found so far:
Pi 2 has composite and HDMI out stock. You can also buy Gert's VGA add on for like 9 bucks or build your own for VGA out. From what I have seen though the VGA doesnt go down to 240p. I am hoping that someone can confirm it can do 240p, if not I am thinking the following options:
1) Gert's VGA + CRT Shaders + 31khz Dsub on Blast (just need a basic scanline shader since it will be running on a 31khz CRT)
2) Gert's VGA + VGA to RGB stepdown + 15khz dsub on Blast
2a) HDMI out + HDMI to VGA box + VGA to RGB stepdown + 15khz dsub on Blast
Options 1 and 2 seem the best to limit conversions. I am not sure if the PI 2 has enough power for CRT shaders though and would prefer a natural 15khz signal.
Composite connector was removed on Pi 2 models.
you can however configure the CONFIG.TXT for HDMI resolutions that can be passed onto the VGA adapter in most cases:
