It doesn't needs to be a proper AES or MVS size carts. It can be carts using flash memories as price has came down considerably and with properly printed instruction manuals. Similar to Nintendo Switch game packaging and price. Neo Geo X came close but totally dropped the ball with its shitty built quality and rehash of the same games as playable titles.
Remember what sells systems back in the day at launch? It's original title that came package in with a brand new system such as the SNES with super mario world and GENESIS with sonic.
If you want to play and cash in on nostalgia, might as well go all the way with the experience. Not some lazy attempt of releasing a decade old games in an emulation box with non industry standard hardware. Create new 2d content!
Wouldn’t go as far as say it was shitty, tommo used the same molds, the problem is that Asian plastic standards since the 80’s/90’s have changed drastically, this has extended to toys were manufacturers use the same mold to re issue a toy and the plastic is shit and thin, I have bought many Asian reissues now days were the plastic just breaks or melts if left in storage, we will never get the same quality out of anything made back in those days all thanks to regulations set in place, maybe with the whole recycling thing.
I mean they tried but they were one the first mini retro consoles, it’s funny how sakurai even acknowledged it was the first Nintendo switch hybrid so maybe they just got their idea out of The nG x. I’m giving props to snk though they have been seen to listen to their fans from what I have seen in all outlets that they have been stepping up their game, but so far I have seen that the capcom stick has been leaving a bad taste in everyone’s mouth due the fba emulation, the 16 built in games and the price, plus that logo as a stick is horrible compared to the ‘female napkin’ design(which is an oversized home console control pad)...
I guess it's out In japan already checkout this livestream
