Some examples for RPG games(OR MORE GAMES BECAUSE I WOULD SAY THE EXAMPLES ARE ONLY DOING NON-GAME STUFF)?

The important code to include with a devkit are the technical / platform specific things. It is better to look at PC-based tutorials and open-source games to learn how to program games. If ...

But what I don't understand is about GX_SetVtxDesc… How can we use it with multiple vertex desc if we cannot specify the GX_VTXFMT ?
Unfortunately you cannot... it's global for all formats. But it should be cheap enough to enable/disable individual components as required. And you'll probably do a ...

Does the NDA let you tell me if the Nintendo Tools are a software a machine for disc pressing or a compiler.

This small python script will slurp in sdloader.bin and produce a shiny sdloader.dol:

import struct ...

That's quite a neat technique! I've got to try that sometime.

Disclaimers:
- This was written for Game Cube, so you may need to do changes to run it on Wii. All the TEV setup should be identical ...

There are three ways to do bumpmapping on Wii:
- emboss mapping: Put a displacement map into two texture channels and use GX_TG_BUMP0 on the second texgen to distort the texture coordinates based on the light position. In the TEV subtract the second texture from the first texture.
-- pro: cheap'n ...

Do you have -g in the linker flags, when you create the elf, as well?
BTW: For a test find the address of main(), and see if you can resolve it from the address. And there is a chance that the crash is outside your program.
Have a look at the map file, or the section information printed by readelf ...

¿What's a DSI exception?
An illegal memory access, most likely an invalid or NULL pointer.
¿How could I translate de Stack Dump into lines of my code?
Usage: ./powerpc-gekko-addr2line [option(s)] [addr(s)]
