So this is meant for the LR Platformers, but I think it might work with others. This was an adaptation of a script Dale wrote in an earlier version that no longer worked. I had to tweak some things and write some simple codes in other places. I'm honestly surprised it worked lol.
STEP 1:
First Open up your game settings and go to the User Variable Tab. Click the Add button at the top and then click on the new Variable and name it "onIce" Be sure to leave the value at 0.
While we're in here we will also Go to Project Lavels > Tile Types and Click Tile 13. Rename it to something like Ice or Slippery.
Step 2:
Next we need to make a new .ASM file to apply to our Tile 13. Go to your NESmaker folder then go to Routines > Base_4_5 > Game > Subroutines
Here we will create a new Text file. Open it up and paste the following code inside of it.
Once you've pasted it go to File > Save as and save the file as IceTiles.asm
Step 3:
Go back into your game settings and go to the Script Settings Tab. Scroll all the way down to your Tile Types folder. No we will go to Tile 13. (or whatever tile you want,) and click on it and hit the Change button. Paste this into the Script path and then close the game settings.
Step 4:
Now we need to paste some code. We going to edit the doHandlePhysics_PlatformBase.asm file. To to scripts > Defined Scripts > Game > SubRoutines > Handle Physics.
Now we're going to go to line 126 and paste in this bit of code.
That's it, you should have functional ice tiles. A few things to note.
1.) Place the slippery tile ABOVE the solid tiles that you want to be slippery. You could make the ice tile itself solid, but I haven't figured out how. Pasting the Solid tile code into the ice tile code makes this weird sticky tile that's kind of interesting.
2.) The physics aren't perfect. Jumping completely cancels out the forward momentum. I'm not quite sure how to fix this yet. Maybe someone else can figure it out.
3.) I don't know if this works on other Modules, so you'll likely have to try and adapt it for yourself.
Update:
1. It doesn't work in Adventure Modules.
2.) You can carry out your horizontal momentum if you stack the slippery tiles even higher up in the air (at least as high as your jump height)

Code:
;; set the ice bit:
LDA #$01
STA onIceOnce you've pasted it go to File > Save as and save the file as IceTiles.asm

;; object is on ice?
LDA onIce

LDA #$08 ;;<<-- Change this to anything between maybe 5-10 to get decent ice physics. 8 is pretty solid.
