Ripping sprites from raycaster game maker isnt even that hard: all the files sound and images files (not the weapons they are bmps) are not in any file format so just add .png to the end of the name of the files and boom now you have a sprite ripped do the same with the sounds
Raycaster game maker Notes: All the weapons past weapon 3 use the same sprites but the idle animation has text saying empty (weapon slot here)
