Have any Ecco prototypes been found?

[KeyboardCowboy]

There's a dumped ROM of an early Alpha version of Ecco II for Genesis/Megadrive but I've never heard of anyone with a physical copy of it. I suspect when Paradox dumped it way back when they had a pirate copy of the prototype since the SEGA logo is conspicuously absent kind of like the Sonic 2 prototype.

Would anyone know about this? Thanks!

I have an ECCO beta for PS2, but not for any other system. I don't think those would necessarily be pirate copies, sometimes in development they are just not implemented yet.

I'm working on an Ecco 1 (MD) proto. Hopefully I'll be able to get it.
