Sometimes, roms can't be dumped right away, or have some protection, so they are coded around. Now, why will newer versions of mame not work with older romsets? Romcenter can help you find the right chips in your collection for the right games. When you want to play a specific game, you need to find the right combo of chips.

So think of your mame collection as just a bucket full of ROM chips. So in some setups, you need pacman to run galaga. Sometimes you will have parent / child roms. That's why you will see them grouped together because switching between the two games is just flipping a voltage switch between 2 roms on a board. A pacman board isn't all that different than a galaga board. Namco made pacman and a bunch of other games in the 80's, all using similar boards.

Thats why mame games are stored in zip files. An arcade game can have like 10-20 ROM images.

just follow that in what they offer.Ī mame ROM is not just one ROM like on the NES. this is surprisingly common as when many older roms were dumped nobody paid attention to the rom labels.īad dumps get replaced with good dumps (somebody just redumped one of the roms in one of the super hang on clone sets which was previously non-working due to the only known ROM dump being bad, with the correct ROM dumped yesterday we can update our source files to reflect that)īasically lots of reasons, we strive for accuracy, so aren't afraid to change things if they need changing. 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)
