Make sure that you reload your rom to see if the tile is working, sometimes the colours might be wrong and all you will see is a patch of a single colour, especially with trees. Make sure to completely change the colours just in case and then put them into the palette colours too make sure you have the right tile. If this doesn't work, go back to the tileset and completely erase everything except for the main points of it. (The outline and text inside the sign) Then recolour it. Post here if you have any problems.

Essentials:
• Load the tileset and click save.
• Reload the whole rom to make sure it fits.
• Redo any tiles you did if it doesn't show up properly.(It would even be best if you made a guide for the tile. Paint it completely in different colours, red, green, orange, yellow and place a key to signify which colour is what colour on the palette.
For instance.
[] is [] on the palette.

When changing the colours of the tiles instead of the actual tile, like the blue house I changed to red be weary that it can stuff up the tiles altogether. The next time you open the rom or in a few minutes of changing it and going to another map your tile can stuff up and turn different colours from what you chose, this also appears in the game time to time. Just to warn you.

When changing a tile make sure that you don't change a tile that is very important in the game, the five green tiles that make up the ground are all used, if you change it into something solid it will show up on the rest of your tiles, and the tile will be included in the grass. You might find pieces of houses everywhere.

Make sure that you NEVER create extra spaces on a tilesit but getting the size of a tile and pulling down the bottom of the tileset to make extra spaces, it WILL ruin the tiles.

If you want to change anything that needs to be in the tileset, make sure you experiment with another copy. Or if you wish to change the colours of the tiles use a palette editor, tutorials are around here

There is one trick in AdvanceMap that is very helpful, but it requires patience.
In the games there are some tilesets that are just wierd glitched tiles. You can easily make them into tiles you want. The tilesets usually are after 50.
• Choose the display grid option in block editor. (Only in newer versions)
• Save the tileset.
• Open it up in paint, there should be all these sqaures with tiles in them. If you load it again the lines from the squares will actually show up in the tile.
• Delete everything inside all the squares. Now you should have a tileset with nothing but squares.
• Get the tile you want, it could even be a new house without the struggle of placing the tiles in the correct order. It could even be a massive building you couldn't make on an original tileset.
• Copy it, and paste it into your tileset. Arrange it so that it fits into the tiles without a little bit overlapping anywhere.
• Add anything else you need in the tileset and load it. But remember at the end to delete all the rest of the lines.

You should have your own building complete there, but the bit about patience comes in now.

You have to order and arrange all the tiles yourself. Sorry, but thats the way it has to be :P.

Screenshots will be added soon.
