I have ordered the prototype NGT30s from OSH. I decided not to modify the board (like make any Through-hole components SMD or anything) because I am terrible at SMD resistor sizes and couldn't figure it out. Should get the boards in a few weeks :D
The new firmware will be pretty much the same as NGT20 firmware. The board is just improved for flexibility and an added PS2 port, shrunken down and made more affordable. I want to add something fun to the firmware but I have no idea what. The current NGT30s have no NTSC/PAL port, so much of the RAM is not used and many cogs of the Propeller could be used. If you have any thoughts let me know!
