If they use the physical carts/discs, are FPGA based, and the emulation code is made by someone with the same caliber as kevtris, yay. Otherwise, nay for me. I don't begrudge people wanting emulation typical for today, especially in the name of preserving games for the future. But personally I don't use normal emulators. I've only bought non-official hardware recently because that hardware fits my requirements.
I find even official console minis to be kinda garbage in both form and function.
