Wow, any details? Somme code ? A repo ? What graphical output? VGA or hdmi ? What input? This is very intriguing...
Input happens via a N64 controller! Those are actually fairly easy to work with at a low level.
The code is not public, though I'm considering open sourcing the project when it's done. Moreover, there's a lot of additional details that I could potentially go into, so I'm considering also writing a few blogs posts with more info if people are interested!
I suppose your target audience is mainly more familiar with verilog (though not necessarily I suppose - could have only ever used VHDL) but I'm interested in playing with it, just haven't used verilog, or FPGAs at all, since university.
Then look at the "output" subdirectory and you'll find a verilog generated file for each example of the parent directory.
Did you use your Wyre [1] language to develop it? I saw the examples on Github, and seems pretty interesting. Its cuts quite a bit of the verbosity of Verilog. I'll give it a try.
In terms of hardware, I'm using an iCEBreaker dev board [1] which has worked really well (A nice bonus is that the board has a 16MB flash chip, which can be used for storage -- this is what the Minecraft clone uses to load the map and textures from on startup).
On the software side, I'm using the open source yosys/nextpnr/icestorm toolchain which is a lot faster than the vendor supplied tools. I mostly figured things out by just trying stuff, so a high iteration speed definitely helped here!
