"Defeat Dr Robotnik" is working for me. (jun/2015)

The achievement "Dry As A Stone" is not working with me. May anyone help?

The "Dry As A Stone" is activated when you finish Chemical Plant Act 2 and is awarded when you finish Aquatic Ruin Act 1.I had to use the Level Select cheat to transport to Chemical Plant Act 2, beat the boss, and then try to get the achievement.

keyo, i did as you said, but it still doesn't work. Is your rom japanese? Mine is (U). Thanks.

I got the same rom as you and the achievement worked well now. Thank you too much. o/

Just checking, do you not get the Chaos Emerald achievements if you use level select? I read in the S1 page that it disables level-based, just making sure cuz it didn't pop them for me but i used the level select to keep returning to EHZ.

(Which is how I did it on console and Android 2013 versions, heh)

Anyone notice how you could technically get all the achievements without using Sonic at all? Assuming the descriptions aren't forgetting anything of course...

You can put another Perfect achievement in Chemical Plant Act 1 :D

Playing with the cheats activated, especially the Super Sonic cheat, gave me the 'Professional Collector' achievement. Some of the others activated simply by letting the game go into demo mode at the title screen. Bug, or just hilarious coincidence?

Don't Look Back works, just don't hit Left before you start the game either.

ra reads my sonic 2 rom hacks as the original sonic 2 for some reason.(was using sonic 2 delta and robotniks revenge)
11 Jun 01:22
Artemis
I'm unlocking these achievements with the delta hack which would be fine but it uses Sonic 1 special stage progression, so "professional collector" is impossible to get. Is there any way I could disable achievements for just this game?

For some reason I can't unlock achievements in this game. I've tried various roms but none seem to work. Any help on why this is the case would be appreciated.

Nevermind, I fixed it by running a different Emulator. I was using Genesis Plus GX which worked with getting Achievements for Sonic 1, but didn't seem to work for Sonic 2, so I switched to picodrive and that seems to work for Sonic 2.
