The Sega Vintage Collection version for Xbox 360...

Is it just me or did they rig the chaos emerald stages for the Sega Vintage Collection version of Sonic and knuckles 2 be super hard? Even the first chaos emerald stage is hard. And I used 2 be able to get the chaos emerald on the first try in the first stage. Same with Sonic the Hedgehog 2. They used 2 be so easy. What did they do 2 these games???
