I think i've more or less decided on my direction for Lost Levels enemy sprites, mostly just subtle tweaks to the originals... if some of them are rough, i'll work on them. SMB1 and TLL are a lot harder to work with than the other games because of all the shared palettes and the palettes changing between level themes.
Bullet Bill and Piranha plant are actually based on new art they made for Lost Levels.
And Cheep Cheep is based on variations of of the original art made for Super Mario Land 2.
But I sometimes feel like some of the changes are a little TOO subtle. So I considered someone's suggestion a few pages back where I alter the sprite's a lot more heavily, like the enemies in Super Mario World once you beat the special zone. Their approach of changing Koopas into Mini Marios and Piranha Plants into jack-o-lanterns is a little too weird for me so instead, I thought I might try some off-beat designs that exist elsewhere in the series.
The Goomba comes from The Legend of Zelda: Link's Awakening, the Buzzy Beetle from Super Mario Land 2, the Spiny, from Super Mario RPG, and the Blooper from Super Mario Sunshine. I'm open for suggestions on designs to use for the rest of the enemies, but I think i'll be keeping Bullet Bill and Piranha Plant the same since they're actually based on Lost Levels Art.
This will be an optional version since I know this could give some purists an aneurysm. I'll be using this version personally because I want TLL to feel as different from SMB1 as possible.
With that said, I really wish I could change the backgrounds and add new music for the optional patch, because I've found 16-bit versions of Super Mario Maker 2 assets that would go a long way in selling that illusion while still sharing it's blood with SMB1.
My favourite part of this comment is my later plans to put this version of All Stars on a SNES Mini XD
An Advance to Snes hack of Allstars is something I've wanted for a hell of long time, and now that the game is disassembled it seems more feasible then ever. If you can find someone to do this, please do.
It's not within my skillset, but if someone is able to import it, i'd happily let them implant it into the hack. Although I think it would be for the best that first someone makes a Super Mario All-Stars with Advanced and Deluxe exclusive content as a stand alone project seperate from this hack. That would make purists really happy and it could be used in future projects, I could update this one later... ( with help of course because I wouldn't know how to do it myself. )
In the NES SMB3, when you beat the game you get a full supply of P wings when you play again. You should see if you can make that happen.
I think it should stay the same to be honest, thanks to SMAS's save feature, you get to keep all of your inventory between sessions, so as long as you remember what you haven't used before you save and quit, you could build your own inventory. I've grinded world 4 to get a whole bunch of P-wings and those clouds that skip levels, it's made testing SMB3 a lot less painful... just remember to reset instead of save and quit.
