Very interesting project. The only glitch I found is that some of the tiles in Green Hill Zone Act 2 and 3 flicker, which I didn't notice with the original ROMs. Other than that, it works perfectly. Keep up the good work.
Interesting stuff. Though when I tried it out on the Genesis Plus GX emulator for the Wii it doesn't work properly, as attempting to load Sonic 2 makes the game freeze, and trying to load Sonic 3 crashes the emulator.
You should tell Eke-eke about that. If this ROM works in real hardware, then the emulator authors should find a way of emulating it correctly.
By the time you read this Eke-eke would probably have fixed the emulator to work correctly. The guy's dedicated to making everything work, I swear :| (This is a good thing, of course =P )
Tiddles tested beta versions of it on real hardware and it surprisingly they worked. =) Sega logo and the menu seemed to work perfectly, there were some issues with Sonic 3 though. I'm not sure about it, actually, Tiddles said there might be something wrong with his flash-cartridge, Sonic 3 worked once, but then crashed on later runs.
I just got an old parallel port computer out of the museum to test it on my old MD Pro, and I'm afraid it's having the same problem as the other flashcart: Sonic 3 just won't go. It hangs on the black screen once the menu's faded out from selecting it. I did indeed get it to fire up once though, on the other cart, and it seemed to work just fine, although I didn't try playing a save and testing that SRAM was stored (it probably would have been hard to say since I never got S3 going again!) I wish I knew what the difference was that one time. That oddity still makes me reluctant to rule out some kind of hardware problem over here, but nevertheless, that's two flashcarts out of two for me that aren't playing that bit.
Random suggestion: if you take either of the flashcarts that worked and delete/clear the SRAM, does it work again?
I can't for the life of me remember if other compilatiosn did this, but when you're in a game and soft reset it takes you back to that game. Probably meant to happen, but again I don't remember.
Hmm, I remember wondering about that now. I'll try to make time to test that soon. (I have vague recollections of wanting to gouge my eyes out with a rusty spoon the last time I tried to manipulate SRAM on either, so I want a good run at it.)
I think that every compilation out there does that, except for those pirates that cycle through games on soft reset.
Wow, I really haven't keeping up with this place. This looks and functions great, though like other people I would like S&K in there as well. Reminds me of back in the days a few years ago when I had the idea for a future ProSonic project where the four games were to be packaged into one as if it was one game.
THIS WOULD BE SO PERFECT ! I have always preferred the sprites, monitors and shields of Sonic 1/cd. Hypothetically speaking, it would be great if 2 versions were released: Something like "The Sonic Trilogy: S1 edition" and "The Sonic Trilogy: S3&K edition". If, in addition to what lordofsquat said, there were also small cutscenes connecting the games stories together, and a sega cd release (cd quality music fuck + ability to customize the soundtrack), I would nerdgasm with the strength of a thousand dragons.
