Snow in SMB2
« on: March 19, 2016, 03:31:32 pm »
So I would like to make a personal ROM hack of SMB2 for a friend. I would like it snowing all the time, like in SMB2 Christmas Special. I can't seem to get it to work though. Can someone please help me? Thanks!

What have you tried? What isn't working?

I tried copying the snow from the CHR of the Christmas ROM to the SMB2 ROM.

I don't know anything about the SMB2 Christmas Special, but I opened SMB2 in a tile editor, slapped some white dots on the sky tiles, and snow happened.

...Nope. The result was ugly and incomplete. I was just checking to make sure it works.

How to fish: Open game in FCEUX, open Name Table Viewer. Placing the mouse over a sky tile shows the following:

Spoiler:

Note the Tile ID: FA. Now open the PPU viewer:

Spoiler:

The background tiles are on the right. Find tile FA. It is below the water, to the right of the question mark and two dots.

Now open up YY-CHR, Tile Layer Pro, or whatever your preferred tile editor may be. Find the same arrangement of tiles:

Spoiler:

Note that the tiles are repeated, once for each frame of animation. Now you can either draw your own tiles or copy tiles from another ROM.

Now you know how to fish.
