How to rip from Game Maker games???

[You Gotta be Joshing me]

I've been trying to rip sprites from the fanmade Sonic 1 8-bit remake, wanting to rip sprites for use in a current project, as well as post them on TSR, after doing some research I found that the game was made using Game Maker. I've already extracted the contents of data.win, (twice, both using different methods) but it won't let me view or edit it as an image.

The first extraction was done using a QuickBMS script called yoyogames.bms, the second was done using Altar.NET

EDIT: Turns out I was looking in the wrong place, the Altar.NET extraction contained some large sprite sheets containing every sprite asset in the game.
