The decomp of FE8 as reached a point where it is now possible to directly modify the source code of the game and recompile it, like it’s done in pokemon romhacking.
Using the decomp as a base has multiple advantage over buildfile, like better control over the game memory, but more importantly not having to deal with fixed address and being able to make reverberating change to the codebase greatly increase what is possible to add to FE8. I was, for example, able to increase the inventory limit to seven items and add a brand new weapon type thanks to being able to increase the size of the character struct, something that was much harder with traditional hacking method.
However, essentially every patchs will need to be ported to the decomp manually for them to function, which represents a lot of work. I guess this thread is basically an interest check for community lead fork of the decomp for the purpose of making it usable for modern romhacking, similar to pokeemerald‐expansion. I personally believe that this has immense potential for the future of fe romhacking and it would be a shame to not exploit it
