Sylvain Munaut explains how he ported and ran Doom on a tiny iCE40 FPGA using a RISC-V softcore.
How I ran Doom on a tiny ice40 FPGA, using the iCEBreaker board. Looking at hardware / gateware / software and comparing it with the original requirements for DOOM classic in 1993.

Doom running on SweRVolf SoC on Nexys-A7 FPGA
Not the best implementation, but I am happy it even worked! Based on Sylvain Munaut's implementation on the iCE40 FGPA: [video

Final thesis
Hi all,
I'm about to finish my undergraduate studies in Computer Science, and I am required to do a final thesis about a certain subject. My professor gave me the idea to develop this thesis about trying to replicate running DOOM on a FPGA (using a risc-v CPU, which has already been done, similar to this), and then trying to port another game with similar specs as DOOM to the same FPGA.
Although I have completed computer architecture courses and I am familiar with the risc-v architecture, I have never worked with FPGAs or hardware description language. Will this project be too difficult to implement due to my lack of knowledge in this areas, or do you think it's feasible? I…
