Pressing start at the title screen brings you right into a level select instead of the "data select" menu from the final.The title screen only lasts about eight seconds before going into a demo, while the final version lasts throughout the remainder of the title music. The logo uses a very basic color palette and is missing the background and lacks copyright information. The audio quality of the Sega scream is also significantly less in comparison to the final, possibly done to save space on the cartridge. However, the screen adds horizontal lines across the screen as Sonic runs to the right for some reason.

The Sega logo screen is the same one used from Sonic the Hedgehog 2.The stage palette table and the data it points to for one earlier build still exists in its entirety. This data includes the stage layout data for Lava Reef Zone Acts 1 & 2, and various 2P zones in various states of completion. The second chunk (1EAF4A-1F6FFF) contains a few leftover stage layouts and palette data from various builds of the game.Mapping (Levels\CGZ\Blocks\Primary.bin) - partial?

There are various references to source code and assembler linking data for Star Trek: The Next Generation – Future's Past, mainly in the area where the sound driver is located.

The ROM contains two kinds of leftovers.

Programming for objects, stages, and more that would be completely removed from the released Sonic the Hedgehog 3 ROM are still present in this build. As such, some of the content in this prototype would be eventually cut from Sonic the Hedgehog 3 but would resurface in Sonic & Knuckles.

This build of the game reflects a time during development when the developers were beginning to split the game into two.

While the EPROMs have a date written on them, the header suggests the ROM might've been built sometime in October of 1993.

After that, it's obvious the game is running on the same emulator slightly updated. You don't need any more proof than his name in the credits. We all thought he just moved on with life or something, but when SCC was announced, it was a heavy suspicion that SEGA just contracted him to develop for them. Even if he did, he has the right to withhold later versions.Ībout 2 years ago, i talked to Lordus but then he mysteriously disappeared. And Lordus never released the emulator open source IIRC. There is overwhelming proof that it's the same thing. But there is no doubt that it is the same emulator updated and packaged as a commercial game. I would surmise the speed loss to be something to do with the new features. Still looks like crap, but is a bit better This is why the game required a 64MB cartridge even though the entire Genesis Sonic game collection only takes up a couple of megabytesĥ- large rom support which allows you to play S3K and S2K.Ħ- SCC has slightly different looking scaling.

It's streamed via the DS hardware now instead of being inside the rom emulated. There are a few key differences in the latest JenesisDS and SCC-ġ- SCC fixes the sprite/background priority issues seen occasionallyĢ- in SCC the special stages in Sonic 2 and 3K no longer appear as a glitchy messģ- in SCC, the Lava Reef boss scrolls correctly and isn't obscured by the lava anymoreĤ- in SCC, the sound effects and music aren't emulated at all, but each individual track and effect is held in its own file when you unpack and look at the rom data. That's the same person as Lordus, the programmer of JenesisDS. Look for Stephen Dittrich as head programmer on that. The author of JenesisDS is even credited in the staff list option on the main menu.
