I couldn't figure out how to open the conquer.mix which is inside the raed.mix, here's what it looks like to me: (See screenshot, that's what my XCC mixer looks like when I've opened raed.mix, can't for the love of god open the sub-mixes).

Hey guys, So I want to do a tattoo using some sprites from RA1 and I've tried using XCC mixer (I think 1.47 is the one I got), but it won't let me open conquer.mix. I had to open raed.mix because conquer.mix was in it, but XCC mixer then wouldn't open conquer.mix, it just displayed the list inside raed.mix. Not sure if I'm doing something wrong though, all help appreciated! If anyone has original spritesheets lying around though I'd be extra grateful if you could share. I'm looking for the rifleman, grenadier, flamethrower, dog! I can't remember if camp fires existed but if they do or some other sorta-looking-like-camp-fire fire exist, I'd appreciate that too. (Otherwise I'll just have to come up with something) Cheers!
