[HELP] Editing tile graphics of SNES PoP 1

Postby starwindz » November 16th, 2011, 1:00 pm

Is there a way to add or modify the tile graphics of SNES PoP 1? I would like to improve the compatibility of PC to SNES level conversion. Also many SNES mods will have mod-specific graphics by using this technique.

I have seen some topics regarding tile extraction but I could not find any information for editing the tiles.

Any ideas?

There is an issue for PC-to-SNES tile set conversion. For an example, some tile set of SNES version is missing for PC to SNES conversion. See the following screenshot.

I would to like add or modify some tile set in order to fix this incompatibility.
Is there any kind of tile graphic editor or techniques for editing tile graphics?

Well, the format of the level graphics is known.
There are two important things that should be distinguished: level tiles and graphics tiles.
The level tiles are those that you can see in the dropdown lists of the level editor.
The graphics tiles are 8*8 pixel images that are used to build level tiles. (Or any other graphics.)
Each layer has a limited set of graphics tiles. (256 or 512)
Here's an image that shows what I mean:

There are many other combinations that are not present in the level tiles, for example:
Door with pillar below: the existing graphics tiles are enough.
Torch with door below: the 05 over 07 shown above is needed.
Pillar with door below: the 05 over 07 shown above is needed.
Wall with door below: needs a new graphics tile: 6D over 07.

The created new graphics tiles could be placed into the place of the empty tiles: 3A, 42, 47 or 48. (00 should be left empty.)

The graphics is compressed in the ROM, so the best solution would be making a game-specific graphics editor.

If the format of the graphics is known is there any way to extract graphics edit them and then put them back in the game? I would love to do some new graphics for the snes version, as the pc version's palette is too limiting and there are no proper background tiles etc.
