Quoted from remf:
already have a sf II cab and just bought golden tee. I’ll leave that one as is, but I want to mod the other. On a scale of 1 to tequila shot, how difficult is it to upgrade? Also, is there a place I can download all of the games I want for free or is there a price for that as well?
Pretty easy to mod. If you search my posts in this thread a page or two back, I linked a video how to add a Raspberry Pi to a stock machine. If you replace the monitor with something better that has HDMI outputs, you can skip the encoder board. There are all kinds of A1Up premade images floating around. Very easy to install onto your Pi.
