If you take the original list and pull out the analog video, is this still interesting?
VGA
HDMI
Video out (CVBS)
USB
JAMMA
RGB OUT (via JAMMA)
Some sort storage that allows easy to update software and ROMs
SD Card (up to 32g)
NAND flash 4G for OS + Emulators + front end.
What are the killer features that had folks interested in this project?
How new of games does something like this need to support?
I think so. Although, I am less than likely to purchase another tube again.
Also, where is the audio out if I'm not using HDMI?
I can think of other things like adding wifi or bluetooth for audio & peripherals. Adding android would be neat too.
Killer features:
The notion I could connect my controls to PCB, monitor and load the games and be on my way to gaming. The goal as I saw it was to be xxx-in-1 that didn't suck, that you could update the emulator on.
As I'm looking over the list. The rPi is this board, but has faced harsh criticism about being too slow. What other board would be most suitable?
