This is from my MazeChase game and it features dynamic tilemapping:

Pretty much, it stores the tilemap as a 64x96 black and white picture. I pixel test a spot and then I pixel test the surrounding pixels. Depending on the surrounding, the tile changes. For example, pretend o is pixel off and x is pixel on. We are looking at the center:

o x o
0 x x
0 0 0

For the maze game, since the pixel above is black, I will use a tile with an opening upward and since the tile to the right is black, I use a tile that is also opening right. This way, each bit can be one of 6 tiles It makes it verrry easy to draw tilemaps and pipes and whatnot without the user having to cycle through tiles. Also, I noticed this method on my Advanced Wars 2 game (for the GBA). You can also apply this method to do multiple types of tiles as well (like mountains and trees that vary depending on the surrounding). For that, you will need more layers.

EDIT: As a note, when the program in the screenie is in map editor mode, all it is really doing is turning a pixel on or off on the map and then checking the surrounding pixels to see what changes. The method allows for easy editing and scrolling

[13:28:43] <+OmnomIRC> (O)<Xeda112358> Ah
[13:29:06] <+OmnomIRC> (O)<Xeda112358> well, you see, when a mommy and a daddy love each other veeeerrrrrrry much

[13:29:30] <+OmnomIRC> (O)<Xeda112358> they call up the stork farm and have a baby delivered
[13:29:51] <+OmnomIRC> (O)<JoeyBelgier> That does not answer my awkward question of the day, though xD
[13:30:00] <+OmnomIRC> (O)<mrmprog> thats not how my mommy told it:(
[13:30:12] <+OmnomIRC> (O)<Xeda112358> It just so happened that I was from an odd end of the stork patch et voila

[13:30:48] <+OmnomIRC> (O)<Art_of_camelot> Yea, from what i was told, it involved, a mail man a bottle of tequlia, and a lot of free time.

o.o

I had coffee today because I have to write a paper due tomorrow (I have not had time). So maybe, if I finish early, I will be up all night programming. Sleep deprived programming is the best o.o <--- still my eyes

As a quote from the link JosJuice provided:

• Sixteen 32-bit general registers (eight banked registers)
• Five 32-bit control registers
• Four 32-bit system registers (SH-3)
• Six 32-bit system registers (SH-3E)

There are a few I am not sure what permissions are like on certain registers, though :? (I probably have easy access to the sixteen and the others might be more difficult). Also, I really like this instruction set o.o

Dowloaded

Howdy And good luck on your geek training o.o
For energy, here you go!

Yeah, I was thinking of the same Axiom, probably, but since I already have most of it already programmed in, I am fine
