![]() ![]() Rom labels (used as the filenames in the zips) get updated when evidence is presented to show that our existing labels are wrong. ![]() (not happened so often recently, but one day hopefully we'll be able to find a way to read the actual protection chips from things like Rainbow Island and Operation Wolf, at which point the romsets will change and our emulation will become even more accurate - a lot of people complain there are flaws in our Operation Wolf simulation right now) Things like protection MCUs get dumped / decapped meaning protection simulations in some games get removed and instead the protection chips get emulated as CPUs, allowing for a more accurate level of emulation. (this has happened recently with a lot of CPS1 sets where said logic chips control the tile addressing amongst other things, it was previously just guessed) Previously undumped roms and other things such as PLD dumps get added to existing sets, not everybody has the capability of dumping these (and until a few years ago nobody really bothered) so they end up getting added to sets much later. ![]() ![]() Previously undumped versions of games end up being dumped and added sometimes causing sets to be reorganized (a newer version of Bubble Bobble II was added in 0.164 for example meaning the set previously known as bublbob2 is now bublbob2o and the new set is bublbob2 due to being a newer version) New roms for previously unsupported things get dumped, support for them gets added (sometimes initially in a working state, sometimes a non-working state) ![]()
