There already is a really good Achievment Guide I found and I couldn't do any more than make a worse version of it,so I'm just linking to it so you can still use it.

Use these Maps to find the Robot Generator,Metal Sonic Hologramms and good places to Time Travel.

TAILS DISABLES ACHIEVEMENTS!

Since a few people started asking for a 100% save file I thought I just add it to this guide as well.

Save File (Google Drive)[drive.google.com]

Put this file at Steam/userdata/[random number]/200940/local (make a back-up just to be sure) and replace the already existing file with it.If you still want to keep your own save file for later just copie or rename it.

Save slot 3 already has 6 time stones collected and all robot generators and metal sonic holograms destroyed up until Metallic Madness so if you get the last special stages and the last two robot generators there you should get both achievements for it.
Credit to A Cuppa Tea for setting that up.

You can rate this guide if you want or even favorite it :D
