DX achievement "Mission All Acomplished" not unlocking

[AlexHidanBR]

Hi! I tried today the "Mission All Acomplished" achievement but even if I got all the 60 missions clear, the achievement did not appear. I tried to re-download both Sonic Adventure and DX achievement and it didn't changed.

How can I unlock this achievement? I don't want to try all over again if not sure it will change something...

Check your memory; if the game's file size is 1.5GB (which it should be after redownloading) it should unlock if you redo Mission 1.

And if you had no trouble with the Metal Sonic achievements, there's really no reason it shouldn't have unlocked.

as veedrock said, if the file size is 1.5gb, playing any mission again will unlock it for you. if the file size is 1.6gb, delete the file, and download it again. you need the 1.5gb file to unlock the achievement

Thanks! I did what you said and I got the achievement! =)

I just finished the missions via the Dreamcast Collection disc and the achievement didn't unlock. Any idea what I should do?

The Dreamcast Collection disc is bugged , i had the same problem . If you are desperate for the achievements the only thing you can do is buy the full game off of the marketplace , that's what i did.

It sucks i know you can write a dirty letter to SEGA but i don't really think they will do anything about it.

If you do buy the full game you will probably need to do the whole game again to get the Metal Sonic achievement.

If I didn't meet the requirements for Metal Sonic yet, would it affect me?

I have 125 Emblems (all of them except the Chao ones), so I haven't actually met the requirements to unlock Metal Sonic. Anyone know if I am spared from having to blow all that time replaying the game again as long as I didn't obtain all of the emblems?
