A flash cart for neo? sounds like an interesting idea but in the other hand makes me remember a teenager downloading ROMS for NeoRage all exited the first couple of days just to get bored after, maybe I am getting old and I need a hobby or the idea of acquiring carts still amuses me.
I don't own a multicart for the same reason, part of the charm all these years have been getting the original cart not a boot because it is part of the SNK legacy, ways to play games you don't own have existed for years but we are still in love with the original smelly AES carts, we still bid on eBay for insane amounts and prices can only go higher, the tool for programming? bullshit the UB incorporated PC2NEO long time ago, new programmers there are just a bunch, really dedicated ones with releases just a couple.
Do I need a flash cart? no! and I bet most of the people here either.
I dare to say it will go down in neo history as all those multi carts or converters have in the past, who owns one also haves an MVS and AES a bunch of carts for both, it's a novelty and amuses a couple of days and then becomes a dust collector, and you keep buying carts.
just my opinion nothing else.
