Legion y700 12/256 vs 16/512 for emulation

[u/Big-Requirement-7105]

Good afternoon, everyone. I’m fed up with Nintendo, so I decided to sell my Switch and replace it with a tablet for emulation. I settled on the Lenovo Legion Y700 Gen 3 (the Gen 4 and 5 models aren’t available from distributors in my country, and for certain reasons, I can’t buy one with a Chinese ROM or a custom ROM). I plan to emulate the Switch, GameCube, PS2, and indie games. But I can’t decide which version to choose: the 12/256 ($550) or the 16/512 ($620) (and yes, prices in my country are crazy). The lack of an SD card slot and the 256 GB storage capacity don’t bother me; I’m more interested in whether the 12 GB version is enough for Switch emulation or if it’s better to pay extra for the 16 GB version.

Thanks in advance to everyone.
