I started ~7 months ago with approximately no FPGA or hardware experience, have now ported ~6 cores from MiSTer to Pocket, and just released my first core of my own, the original Tamagotchi - https://github.com/agg23/fpga-tamagotchi/
If you want to join in, I and several other devs are very willing to help talk you through it. We primarily are on the FPGAming Discord server - https://discord.gg/Gmcmdhzs - which is probably the best place to get a hold of me as well.
