This looks like old Sonic CD minigames

It's such a coincidence, I started working on it again today I'm in the process of modifying the code to use with t0xic_kitt3n and hoffa' engine.

I've also discovered the worst part of programming : converting a giant 6800*3600 bitmap to a 1024*512 tilemap manually

In fact, I have a giant bitmap, a set of 256 16*16 tiles which happens to correspond to the bitmap, but not the tilemap itself

To clarify things, I have the tileset, the final image composed by the tiles of the tileset, but not the order the tiles have to be put in to generate the image (and this is what I want, since the engine uses that).

Can't you find those datas online ?

Or you could automatise the conversion, I'm sure I can make a program that scan the image for tiles and generates the datas as you want (something like the inverse of what I've done there : http://ourl.ca/12441/341898 ), it don't looks that hard.

I would just need the map image, the tile list and the output format.

Ok, but I think there's a background image (the city ?) for the paralax effect, so how will you handle this ? Do you want to use a transparent tile right now (if so, which one ?), or include the city in the map image (if so, I'll have to add its tiles in the tileset) ?

Ok here it is : http://www.mirari.fr/yVxE (made using PureBasic)

A few things : the tile $ff isn't transparent (it's the wave-thing) so for the background I've used the tile $9a (the blank tile). The converter check if the colors are exactly the same to assume which tile it is, so you may have to modify the tileset later (for other maps) : I've already changed some colors, but not all.

There are two programs : "tiles.exe" reorganize the tileset (easier to use/include) and "map converter.exe" well, it's self-explaining

Both works by drag and drop things on it (the unorganized tileset image and the map image).

It just takes a minute or two depending of the size of the map.

The map image you've posted earlier was sized down so I've used this one : http://www.snesmaps.com/maps/F-Zero/F-ZeroMapSelect.html

And I wasn't really sure how you declare a byte field in C (is it possible to make line breaks ?), so you'll see if the output format is what you expected, else I can change it.

By the way, I think you could gain a lot of bytes by using some compression (and then uncompressing the map image on the nspire before races). I can easily add this feature to the program, or even make a map editor when you project will need it.

I've changed the format : http://www.mirari.fr/yVxE
