    Wow that's a good list, nice. Hopefully we'll get all those Sonic 2 carts dumped if my mission goes to plan :P

    Dump the European Mean Bean Machine if you get the chance.

    Aren't there two Sonic Crackers ROMs? An overdump, and a normal one?

    Nobody seems to know where the overdump is, and it may not even be the actual ROM overdumped.

    The overdump is the ROM that was dumped over the "Teenage Mutant Ninja Turtles" wasn't it?

    Hmm... Maybe that overdump should be the ROM labelled as "good" since it's a dump of all the contents of the prototype. If it was a real overdump it would have the same data twice. =|

    I think there's some other prototypes with overdumps that feature more leftovers in the second half, besides this one.

    I think so. But I can't find the overdump anywhere.

    A Teenage Mutant Ninja Turtles prototype. Though, I don't think there's a Ninja Turtles hacking community that would be very interested. =/

    By the way...
    Goodgen is (fortunately) missing some other combinations such as S&K+S1 Japanese or JP2, S&K+S3 European or Japanese, etc. Thanks to Steve Snake we'll be able to get rid of all these possible combinations in a near future, since he's working on emulating the lock-on feature.

    Super Guitar Hero II
    Yeah, since by definition, an overdump is dumping more data than is present, and it would repeat when the non-existant address lines are toggled.

    Unfortunately, I believe my S3 EPROM is not one of those, as I'm pretty sure it only has 2MB worth of EPROMs, based on the part numbers. And since S3 is a 2MB game, there can't be any extra ROM data above $1FFFFF.

    Having the entire GoodGen set kicks ass :)

    I have 6 versions of Sonic Crackers:

    Sonic and Crackers (Beta).gen - 1024K (the "sort-of-known-good" dump)
    Sonic and Crackers (Beta) [b1].gen - 1024K
    Sonic and Crackers (Beta) [h1C].gen - 1024K
    Sonic and Crackers (Beta) [h2C].gen - 1024K
    Sonic and Crackers (Beta) [h3C].gen - 1024K
    Sonic and Crackers (Beta) [o1].gen - 2048K (the overdump with TMNT data)

    My server's currently down, but I should have it up sometime this weekend. All 6 versions are in a 974K 7z archive.

    Sonic Crackers' header says the ROM should be $1FFFFF bytes long, so the "overdump" must be the correct version.

    Wait, Sonic and Crackers? Tails is Crackers?

    Hmm, that sounds odd. Seems like they were intending Crackers to be a 2MB game? But there was only 1MB of code and data, since (as far as we know) the 1MB version works the same as the 2MB one, meaning that the upper 1MB is leftover data (most likely, I would imagine they had a 2MB flashcart, and only reflashed the bottom 1MB).

    Kles: I think that was the name that was on one of the proto boards, IIRC.

    Even from the beginning of your uploading days on your old site (I liked the old logo) You have used 7z. I even E-mailed you a loooong time ago asking you what it was (before I was a member of SWS2b), although you probably have forgot.

    Nice to see you back after a few months!

    EDIT: Anymore of those Gerbilsoft CDs for sale? *shot*

    I call it Sonic Studium because of its header name.
    Nice list BTW.

    Sonic Crackers was a makeshift title... probably hacked in there. I doubt that was the original title screen for that alpha.
