Me and a friend of mine have been working on this very carefully curated romset for our retropie setup for a couple years - we're trying to go for a set of Roms that are "comprehensive" instead of "complete" (the difference between the two being: if you graph the overall quality of any system's entire game library, you'll usually find that about 70% of the games made for any system would usually be rated 2-stars or less by most people - Barbie's Horse Adventures, for example - so, a Comprehensive set theoretically should include all games that are 3-stars and up, which still results in hundreds and hundreds of games per system, but eliminates the vast majority of the "bloat" that you experience if you just dump a complete ROM set into a system). This has been relatively easy to do with most systems, but we've come into a problem when it comes to the romhacking community and it's works:
We decided that when it came to Fan Translations, our filter criteria for inclusion would be "any game that's listed as 'fully playable'", the idea being that any game that's good enough to convince a group of people to do the entirety of the translation work from start to finish must be at least worthy of note enough to be included. However, when it comes to ROMHacks, we can't think of any criteria by which to separate the exceptional from the mundane.
Some ROMHacks are just crazy pieces of work - things like "Chrono Trigger: Flames of Eternity," "Zelda: Parallel Worlds," "Conker's High Rule Tail," or "Pier Solar and the Great Architects" are such incredibly high-quality pieces of work that they deserve to be treated as unique games in their own right and it's obvious we should include them - but for every one of these games there's 10 ROMHacks like "Harmony of Dissonance Sprite Color Fix", which are good and worth playing, but honestly just aren't in the same league. The real problem, though, is that there doesn't seem to be any sort of quality-reference mechanism in the romhacking community that doesn't involve spending endless hours trying out hundreds and hundreds of individual hacks manually.
How do I tell which ROMHacks I should definitely add to the " Oh yeah, I definitely want to play this someday" collection?
