nes-contra-us VS rle_konami

I've been working on disassembling and documenting the US Contra NES rom. I think it's at a state now that I can share. I've created a public repo at https://github.com/vermiceli/nes-contra-us. I really hope that this information is useful for some here. This disassembly is properly labeled which allows for modification without breaking jumps and branching. It includes supplemental documentation, diagrams, lua scripts, and tooling to build the rom. I'd appreciate any feedback on the assembly, for example if there was a better way to write or document the assembly. In general, any feedback, questions, or discussions are welcome. I'm happy to answer with what I know. My next goals with this project are to look into being able to generate Probotector rom (the European release) as well, which is very similar. I also am looking at seeing how challenging this will be to port to the Commander X16. Has anyone looked into development on the Commander X16? The community there has been very helpful so far.

I know I'm totally just replying my own post now, but I'm making progress! The guide I linked previously was extremely helpful, as well as doing some manual address testing with using Mesen and the PPU Memory Tools.I was able to get the following in YY-CHR after converting with RLE_Konami (I'm realizing now that Graveyard Duck may have been more for FDS games) and targeting the address: 0x00012b6b
