The MAMED site was updated with news of a new release, split into 15 game packs. The page update was quite long, so here are some highlights

The CD swap bug has been fixed, but now you need my special version of KOS to run MAMED on your dreamcast, although this version should run any standard KOS application without problems. Disk swapping should not cause any problems, to refresh the screen just try and load something that’s not on the disk by pressing start from the game list and it will rescan the CD correctly.

OK now on to the MAMED packs. All cpu and sound drivers are inside in each pack so they will be too big to load onto /rd and run it from there so they must be on a CD to run preferably the CD with KOS above.
Remember the uncompressed rom size is important but also each driver has to emulate ram chips inside the machine too so don’t expect a rom that uncompresses to 14.6MB to run on the dreamcast you need space for ram chips and the emulator code and even then it might be just too slow.

This one should be much easier to get working. I’ll get around to packaging up the source when I get a chance and hopefully others can make some selfboot images, I’m no good at it with my CDR. Remember this is still beta and there will be problems running some games. Enjoy.

crjack says he has burned a working MAMED self boot image so it looks like its a good build this time, everyone start burning.

Sounds great to me, you can check out the full news update and grab the MAMED game packs here
