Mame staat voor Multiple Arcade Machine Emulator en is in staat om een grote hoeveelheid oude consoles en arcadegames te emuleren. Let daarbij wel op dat de meeste rom-images auteursrechtelijk beschermd zijn, zodat je een origineel exemplaar in huis moet hebben voordat je deze met Mame mag spelen. De ontwikkelaars hebben een nieuwe editie de deur uitgedaan met 0.131 als het volgnummer. De bijbehorende aankondiging ziet er als volgt uit:
Version 0.131
The official 0.131 release has been posted on the Latest Release page. Those of you who haven't been keeping with the intermediate releases will need to take heed of the warning that came with MAME 0.130u1. I'm repeating it here just to be sure:IMPORTANT NOTE: The CHD format has undergone a change with this release. The main reason for this change is to include some of the key metadata into the hashes for the CHDs. This ensures that the metadata is valid and prevents abuse.
As always, make sure you report any issues over at MAMETesters. Have fun!
The first impact you will find is that all of your CHD differencing files are invalid. Just delete your "diff" directory contents entirely.
The second impact is that all your existing CHDs will warn you that they have incorrect hashes. This is expected. Your old CHDs should still work fine, so if you can live with the "bad ROM" warnings, you don't really need to do anything. However, if this bugs you or you want to be "clean", you can update your CHDs, using this command line:
chdman -update
for each one of your CHDs. This will take a while, but will produce CHDs that match the new checksums posted in the drivers.
