Re: Plans to improve / expand the example apps in devkitPPC?

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 you...

Re: Problem with light in GX

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 t...

Re: Commercial Games

Does the NDA let you tell me if the Nintendo Tools are a software a machine for disc pressing or a compiler. The "Nintendo Tools" is all the compilers, libraries and utilities to create a Wii game. You'll need to buy special hardware as well to run and test the game. Nobody except Nintendo themselv...

Re: sdloader.bin start address?

I should say sorry for not RTFM... I just remembered that I still have the installer on my HD and the readme even mentions the start address for people who want to replace sdloader.bin: 0x81700000 This small python script will slurp in sdloader.bin and produce a shiny sdloader.dol: import struct f =...

sdloader.bin start address?

I'm sorry that this is slightly off-topic, but this seems to be the best place: Does anyone remember what the start address for SDLoader.bin is? I'd like to convert it into a DOL to launch with a max drive pro...

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

Re: how to use bump mapping?

I re-uploaded it at http://bin.mypage.sk/FILES/bumpmap_demo.zip , but it may expire in a few days. It would be great if anyone has a chance to permanently host it. 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. - ...

Re: how to use bump mapping?

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'ea...

Re: Trying to understand the exception

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, ...

Re: Trying to understand the exception

¿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)] Convert addresses into line number/file name pairs. If no addresses are specified on the comm...
