18 Feb 18:16 2020		is there any reason achievements wouldnt load on retroarch?
21 Feb 4:14 2020		They wouldn't on versions older than 1.8.2 since I used the "Measured" flag in several achievements.
2 Mar 22:40 2020		About the "Y-Axis" achievement... how are you supposed to destroy/avoid the shielded enemies that can only be destroyed from behind?
2 Mar 23:30 2020		Oh, I realized you can die and still unlock it.
