A 1.6 GHz Core 2 Duo? Granted, it's a laptop, but my Core 2 Duo E7400 desktop of 2009 vintage is almost double that clock rate, I'm sure you could find something just a little bit quicker in the e-waste pile. Does it absolutely need to be a laptop?
Yes, I have my fair share of potato PCs too, case in point a single-core AMD Sempron 140. It's absolutely useless for anything quicker than PlayStation 1 hardware in MAME (it fails my Tekken 3 test e.g. can't even reach 100% even in 240p mode, let alone 480) and looking at MAME benchmarks, it might even be slower than a Raspberry Pi 4, which is just embarrassing. That said, I'm sure the crappy integrated Nvidia nForce 630a GPU is also helping it to be such a slug.
