I've been avoiding replying to the thread since i've not worked on the hack in a few days, so i've nothing to show, and I don't want to run into another situation where my thread doesn't get bumped when I have a real update because of the double posting rule. I've actually gotten in contact with DarkSamus99 again so it seems the wait for the build script is underway again.
looks very good,but and other backgrounds in smb1 game and lost levels too 
You're going to have to rephrase that because I can't make sense of this...
The 1st image looks better, much softer the colors and good changes with the floor tiles and the clouds, its fidelity to the original version of NES 8-Bits seems great when updating art to 16-Bits.
the 2nd image is very saturated with purple and more dark tonality.
I should have mentioned that the mockup is from an older build so the bricks will be the same as in the 1st image. The darker color is intentional to make the colors match the NES game better. I will keep the lighter color skies for Lost Levels. It is just a mockup for now, but DarkSamus is looking into making it a reality.
When I had a snes classic, I remember something about homebrew needed to be 512 KB or larger. So that could be why your standalone demos are failing.
You could also ask here, which used to be popular until the Sluffy went away.

It actually works with retroarch, but I'm not a fan of having to use retroarch when I don't have to. It's not an important matter anyway, the stand alones would be nice to have displayed on my SNES Mini's slick UI, but if it doesn't work out of the box, i'm not going to do a ton of digging to try and make it work. I'm fine with the compilation. The Stand Alone hacks are mostly going to be used for demo purposes, but if there's any sort of demand for the games as stand alones, i'd welcome others to make them work... although it would require the pallet editing to be done from scratch for each stand alone game.
Hey there. This hack is pretty cool! Although, I'm in a mixed bag about SMB3 Mario and Luigi but they're good for the most part. I love their poses but the design of em is weird. I really don't like SMB2 Mario and Luigi. They just.. look weird aswell. I don't know how you can do the SMB2 ones better though, but I've made this SMB3 Mario. Me and my friend are gonna use him in a project (Although with color changes and some minor edits) but if you want I can make a sheet of him.
Well I'm sorry you don't like them, I'd rather not hear that if you don't have a mock up of how to improve it. I have no plans to change Mario and Luigi right now as I think they resemble the art quite well and i've put a lot of time into making sure they resemble the game's art work, which is the main goal of this hack. The only sprites I'm not satisfied with for SMB2 is maybe a few of the small sprites and crouching sprites. Other than that, I'm very proud of my SMB2 Mario and Luigi sprites.
I do appreciate your SMB3 mockup but I prefer what I've done. The Mario 3 sprites are still a work in progress that i'm not quite satisfied with yet so they may change. I've contemplated just doing what the original Mario All Stars did and reuse my Lost Levels Mario with the shirt and overalls colors swapped as a base, but I'm not 100% on board with that idea. A big appeal of the original All-Stars is that they all had different art styles, so I'd like that to be true for the Mario sprites as well...
