EDIT: Here's some more stuff from the test level.

Looks like they tried to give the item monitor icons the yellow border?

Different hurt animation.

Different spring animation.

And a different win animation.

After feeling blessed with the Final ROM Archives, and now this, I feel like I should give thanks for all the great work! The prototype and it's obscure handheld platform nature should definitely fuel some interest back into the reverse engineering scene for sure.

Oh yeah, also: There's a weird data stream possibly acting as padding, duplicated 2 times throughout the final and the prototype, and it is slightly different in both. No idea why.

I noticed that the Knuckles fight uses the normal boss music rather than Flying Battery Act 2 or whatever it had before.

There's no cutscene after it, either.

Also, all the Special Stages use the same palette.

Nicely done!


But that Aladdin prototype - there was a topic here and it's totally definitely not a Summer CES build. I have lots of evidence (though the key is that the 27th is three weeks after SCES 1993) - just figured I'd quash it before it spread further.

Several songs have differences in arrangement, with the most different being Cosmic Casino 2 which has some different notes on the 2nd harmonic lead. Valleybell should take a look at this!

Also the Test level map seems to be this GIF: http://forums.sonicr...showtopic=29461

Would we be able to extract the complete maps?
