A bit of trivia, since the start of the project I ordered the AI agents to produce a handoff for the next agent, so we have the whole timeline for the project as handoff docs: https://github.com/lfarroco/ogre-battle-64-recomp/tree/main/...

Nice I have not thought about this game in years.

I'm not aware of legal trouble involving the the Zelda 64 recomp project, which would have a much higher chance of attracting the attention of big N (especially now that a new version of OoT is coming out).

At least in the way that I see it, a recomp is like building your own turntable to play your vinyl records, after stydying their grooves and infering how they would sound (so I guess that it would be less gray than an emulator).

No one can say anything, no game rom is ever bundled in the official releases of these recomps. We always have to provide the roms. Where from, it's another story.

It's basically the same as emulation as long as the recompiled code doesn't get distributed (which this project doesn't do AFAIK). Functionally the only difference between a "recomp" and traditional console emulation is that the assembly code that the CPU runs is translated to C then compiled to native code, rather than being interpreted or JIT compiled at runtime. Traditionally recompilation was mainly used when porting games to platforms where the emulation overhead would have been too much, like if you were making a GBA port of a Sega Genesis game. With these enhanced ports, I guess the idea is that if you're making a game specific "emulator" anyway, you might as well recompile the code and get rid of the overhead of interpretation.

Note that this isn't the same as a "decomp" where the goal is to make readable source code that resembles something that the original developers would have worked with. A "recomp" simply translates the assembly instructions to C. You end up with "assembly code but in C" rather than idiomatic C code.

This is a recomp project, not a decomp project; the original binary is supplied by the user, mechanically translated into source code at an architecture level (rather than a human-readable level), and patched. It’s AOT dynamic recompilation and the original IP isn’t distributed.

I do agree that decompilation projects are obviously not transformative (the only fair use feet they really have to stand on are purpose and market effect), but recomp projects are a little more interesting and might live on much less shaky footing.

It's sad that we even have to think about this. Ogre Battle 64 is 27 years old now. Under the law that preceded the Copyright Act of 1976, it would be entering the public domain right about now.

It's absurd how long we've made copyright terms, and it's really endangering preservation.

What is a "true recomp"? If it works as the original did, then it's a recompilation no matter the author.

You may not like that the author is mostly an LLM, but the output clearly works.
