Hey, have you played this at all? Pac-Man 2 is one of my favorite games, and early previews had a ton of very noticeable differences.

I forgot about this one !  Different title screen not sure what else.

Tell me if your ever willing to sell the croc beta

put me down for college footballs national championship 2 beta for sega genesis

Updated!

Heres a pic of it, its on an official Fox interactive disc which is kinda neat.
 

Probably never going to sell it as Croc one of my all time favorite games!  Although, a public ISO release isnt out of the question in the future, there are some neat in game differences. I plan on starting a website for ps1 prototypes where I will post screenshots and info on them.

I used to play croc all the time as a kid

Same here man! Isnt the music amazing in that game? The characters, envoronments, everything about that game is so nostalgic!

I used to spend most of my time playing that game

proud new owner of drum roll please.....

2 more proto's
and number 2
NBA *Super* Allstar Challenge

Oh shoot! I forgot to mention I have a prototype of the zelda watch line made by nelsonic. I purchased it from the company when they were selling off a bunch of their proto and demo stuff. It is the exact watch shown in ebay #230424365084. It is just an outer shell, a moc of what it would look like. The buttons are plastic, and do not work. Still, wanted to note it though as it may fall in this category

Only one here. I would love to someday get my hands on anything Mega Man. It just doesn't ever show up.

PSP
Sonic Rivals 2 Sample (Seems to be same as final, but contains a test level not present on final UMD)

Everything should be up to date at this point in time. If I missed anybody/anything feel free to let me know.

Cost $75, and the game is absolutely terrible.

^Is it different from the regular released version? I remember playing the game back in the day, and it wasn't that bad...

The title screens are different (selected in proto is a paw, while in release it is the sun), and I think this game is terrible.

Add these for me (all 2600)
