Good idea. I can already tell you that the Johnny M. Betas aren't really very interesting beyond being "wtf is this game about?". 


Picture proof of the discs' existence (warning might be a bit large. I can assure you they are JPGs though.):

And yes that is a green mark on the blank disc. That is the VF Remix disc. It had no label and I couldn't tell which was the bottom or the top. As a result, after figuring it out, I marked the disc with a CD-R Pen. Fuck collector's value, I did it so I could differentiate it. Turns out the VFR disc has tiny instances of the Sega Logo on the rim of the disc. The FFS disc lacks this but looks mostly the same.



Me holding one of the discs as further proof.

Edit: Just found something interesting out about Shining Force CD beta. 
According to some of the files on the disc, the latest last modified date for the files was December 26, 1994 at 1:14 PM.

This means that Sega of America was in the process of translating and polishing the beta as, according to wikipedia anyway, the US version release date was March 22, 1995. The European release date was unspecific but it was some time in June of 1995. The Japanese release date was July 22, 1994. I'm not sure how reliable these dates are though...
