Ok so i have a question that im not sure how to ask exactly...

Im getting a popeye cocktail tomorrow and Im confused on what games are interchangeable with it... I have a red tent and a while back was going to buy some playchoice stuff off someone but learned that they do not work with the red tent which has a motherboard and slots for 2 sets of roms or daughter cards...  is that the standard for nintendo, just to change the roms which is called the VS. system or something and then playchoice is a different style "motherboard" that uses a small pcb?

sigh im so confused... any help would be appreciated

edit: ok after some more research i see that popeye is a "nintendo classic" connector same as donkey kong jr so i guess that a whole other system on its own... sigh.. maybe i wont buy this i dont need anything else but damn its popeye..
