I honestly never understood why, even collectors, would purposely want "bad" games. (unless they intend to resell based on value?) Rarity is not equal to quality (with some exceptions) and as other have stated your money could be better spent.
Now, I do get obsessing over something that is out of reach, but surely the disappointment you may experience after spending upwards of $300 for a mediocre at best game is fuel enough to dissuade you!
If you have a PS4, the original Terra Cresta
https://store.playstation.com/#!/en-us/games/arcade-archives-terra-cresta/cid=UP0571-CUSA00983_00-HAMPRDC000000001 is available on the PlayStation Store as an Arcade classic for $7.99.
I suggest playing that "sobbering up" and moving on. Also, As someone who only plays on original hardware and wants original games an everdrive is an amazing purchase for
exactly this reason. Invest in that, and play TC2 that way, win/win
