As long as you follow the license of the art you should be fine. I would stay away from CC-BY-SA or GPL licensed assets for this project. CC-BY may give you problems, if there is some kind of DRM in the Sega Master System on Steam. You would want to figure that out.
But OGA-BY or CC0 licensed assets should be fine, just make sure you include attribution for OGA-BY.
If something has multiple licenses, (e.g. it lists both CC-BY-SA and OGA-BY), you can pick one license and ignore the rest. So in this example, you could use it under the terms of OGA-BY.
Unfortunately it's not entirely that straightforward. The question (with CC-BY-SA) is whether or not the game itself is a derivative of the artwork, and there is no clear answer, including when Capbros actually contacted the folks at CC. I think the consensus is you should err on the side of caution, and if you really want to useable asset, you should contact it's original author to ask what kind of use they are okay with, and try to respect that. I have seen some authors explicitly state that they only want it used in a game which is released under a comparable free license, and others that take Kemono's interpretation.
The one area the license is clear is that if you synchronize a -SA asset with something else, the combination counts as a derivative and must be released -SA as well. So -SA sound effects which accompany animations (like a sword slash) would fall under this.
Regarding LPC, there is no feasible way to relicense that whole atlas, as it has several authors that would have to agree. For what it's worth, I know at least Sharm lets people use her LPC assets under CC-BY, and she has made fantastic time sets.
I also got flagged by Mollom, tyring to point out a new asset in the comments section under a collection page. I just directly messaged the currator instead, but still it seems weird to not be able to comment. For reference, here is the comment (plus many close variations on the same theme) that was rejected:
Thanks for the complement! I did put a lot of work into it... I should have learned my lesson, but a few months ago I was working on another cape animation, this time on my 3D voxel characters.
@Boom: The cape he is referring to was from Viking Shieldmaiden, and now on this character. You got both in your collection (which, by the way, thanks for doing such a great job keeping up on it!)

Awesome work, I love it! I especially like how you did the eyes and eyelashes, and the bow. Thanks for sharing!

I love it, especially the no line version. It makes me want to look to see how the other characters look lineless.
Rockin!!!!! Great retro game vibe, it really brings me back.
This is fantastic - thanks for sharing!
Really good work! I like the style a lot.
