The Joey works better on a Windows machine (though does work on a Mac, but is slightly trickier to get it working consistently - on windows it's fine). I have both and I'm on a Mac - which is a factor. Is there any reason to keep the MMC over a GB Operator? I know MMCs are hard to come by and they're 'vintage' in a sense, and some have said to hold onto it instead of returning it, but the GB Operator just looks superior. If I get moving on it, I should be able to get the GB Operator before the return window ends for the MMC, so I don't run the risk of losing my saves in the period between returning the MMC and getting the GB Operator (because knowing my luck, those batteries will die then, lol). It's the same price as what I paid for the MMC, so I'm wondering if it makes sense to return my MMC and use the refunded money to get a GB Operator.

Last night I found out about the GB Operator, which to me looks like a superior version of the MMC in every way- it not only saves/reads/writes data to physical carts but also allows you to play them on your computer and even access special events that are no longer possible (namely for the Pokémon games). Last month I bought a Mega Memory Card to back up the saves of my old Gen 1 and 2 Pokémon games, since someday (likely soon, given it's been over 20 years for those batteries at this point) the batteries will go, and I want to preserve the save files for new batteries. The GB Operator still looks like it'll arrive sooner, before the deadline to ship the MMC back. The question is which has the better features, which is something I can't tell based on their web pages alone. or GB Operator? Price-wise they're about the same, around $55 including shipping. EDIT: I guess the question now is what's better, a Joey Jr.
