No. If you're looking to play most PS2/GC at 100% speed, you're looking at spending $200-250 depending on sales and your standards for your definition of "play".
Like, my $150-ish (on sale) 406H can play "enough" PS2/GC games, but some need me to go to performance mode and a bunch straight-up don't work. Depends on settings though, I guess.

...Retroid Pocket.
I mean it, if you're looking for solid, nearly-complete libraries of GC/PS2, you're not spending less than $200 unless you buy something used off Ebay or catch a deep discount on Aliexpress or something.

Honestly, a real DS, though it depends on what KIND of DS games you want to play on there. Touchscreen-heavy games feel like ass to play on anything that isn't the real thing, but games where one screen's basically just a map or shortcuts or something, you could play DS on all kinds of systems and not struggle with it too bad.
