I have done surface level/basic hacking on many games, and taken a few somewhat deeper. A while back I tried a thread called thread of a thousand ROM hacks where surface level hacks could be done and noted just for no reason, it did not amount to much. What I propose here is we decide upon a game here and reverse it hard. File formats (custom and otherwise), file names, disassembly/ROM map ( http://datacrystal.romhacking.net/wiki/Yu-Gi-Oh!_Dark_Duel_Stories:ROM_map ) , the maths underpinning it ( http://www.dragonflycave.com/rbycapture.aspx ), maybe some pondering of the compositions (it uses a ? beat and * instruments sort of thing) and so on and so on. If someone wants to improve things for the game then so be it. As we are in the DS section I want this to be a DS game, if you want to replicate the concept for other systems then even better. It is possible to pick randomly, however I would want a reasonably playable game used here and perhaps more importantly I do not want it to be one that has already been extensively reverse engineered -- so no mario platforming, zelda, phoenix wright, mario kart, fire emblem, advance wars, golden sun, pokemon, megaman.... and though this is the DS then were we doing it for the GBA I would even dismiss fire pro wrestling. I would also shy away from licensed titles, save perhaps unless the quality was 8-16 bit era Disney-Capcom grade. If it could be something that really represents the DS library then it would be better still. Wiki, megathread, something else. That might have to evolve as things go on. Anyway thoughts from others?
