P1V on Xyloni (Trion T8 FPGA)

Just got P1V working on the $35 Xyloni dev board.
Identifies and loads code from Prop Tool.
Design files below.
It's not cleaned up, just happy to see it actually work.
It's a pretty lame version of P1 though with 2 cogs, 1 kB RAM, 1 kB ROM, no video generator, and no counters. There's no room for more memory, but there is room for more logic.
Clock is currently stuck at rcfast but think can improve that.
Made some notes on Xyloni here: http://www.rayslogic.com/Xyloni/Xyloni.htm

It currently needs a PropPlug for programming. See photo for how, VSS on J1-pin#3.
Tried to get it up to 80 Mhz, but it's not working...
This version does work at 20 MHz though (any PLL setting will give 20 MHz).
Not sure what's going wrong, but it falls off the rails at 40 MHz or more...
