wow, if earlier ones didn't have changed cartridges how do you know which version the cart belongs to? or are they identical even down to the model number?
It depends, as there were a few different ways Nintendo went about producing Players Choice carts. For example:
http://www.rfgeneration.c...nfo.pl?ID=U-064-S-02630-AIs the original release of Turok 2: Seeds of Evil. The original copies were released in a black cartridge.
http://www.rfgeneration.c...nfo.pl?ID=U-064-S-02631-AIs the Players Choice release of Turok 2: Seeds of Evil. These came in grey carts, but didn't have the Players Choice logo on the game. Even the Players Choice logo itself was only a sticker on the box itself. I guess they didn't want to reprint boxes with the PC logo already on the box. Confusing enough? Wait, there is more.
Other Players Choice games, like Kobe Bryant in NBA Courtside had the original release:

http://www.rfgeneration.c...nfo.pl?ID=U-064-S-01141-A. Notice the lack of scans on the PC release? The cartridge was the same for both (maybe minute board differences, I haven't checked), as was the box itself. I haven't seen the manual yet, but the only way to tell if you have a PC version of this game is to have the game sealed. The Players Choice logo was a sticker on the outside of the seal of the game itself. There are a few games like this.
And then there are the colored cartridges like Tom Clancy's Rainbow Six, Hydro Thunder, Rally Challenge 2000, etc., that were initially released in a colored variant. Later print runs had the games in grey cartridges, but AFAIK, there is no box difference (maybe a copyright difference?).
I find it all extremely interesting, but damn if it isn't annoying at times.
Need to know anything else?
