For me, some things did. Other things really just didn't. If you were to realistically state DOSbox's requirements then it would be above 1GB, otherwise they'd be getting a lot of complaints.
Either way it's pretty much irrelevant to the point. Unless you're saying that DOSbox doesn't need more than, say, 32MB to work properly. Emulators always need a LOT more than the original requirements to work properly.
Face facts, Veneteaou, the reason you're rejecting it isn't the fact that the requirements are unrealistically high. It's the fact that, for some reason, your computer doesn't meet them.
