any 1 want to help me make a nintendo cube emulatore?

[lightknight]

those who want to than just email..once i get few people to help me to statr working on it...i will be using Dev C+++ 4 to code it in windows!! and am thinking bout doeing it in direct x 8.1 and openglide!! and i want to sart a n64 emulatore with based on 1964 71 source code with Daedalus 0.08 Pre-1 Source code!!

[Slougi]

Why don't you do it in opengl? isn't that faster?

[sytaylor]

plus the gamecube uses opengl...plus why devC? it has NO help files and i find its compiler results to be VERY confusing

[lightknight]

i have been learning a lot of C++ there ...


i am learning alot in there Tutorials! you should check them out...if you to help me out..

[mesman00]

just a few questions....
if you have been learning from tutorials
1. how much do u know?
2. how long have you been programming?
3. do u konw any graphics programming, such as direct x, opengl
4. do u know any sound programming?
5. do u know anything about the gamecubes technical crap (processor and all that junk) there are very little docs released about it, if any

i hope you are pretty good at c++ and have been programming for quite some time, and havent just picked it up through tutorials over the last 6 months or so. otherwise you are in a lot of trouble. maybe you ought to start out with something less complex, like the NES, especially because it has alot of Doc's on it.

I don't mean to discourage you, but just to warn you

Yes indeed experience helps with writting software.

Now the manufacturer of the graphics chipset for it is ATI.. you won't find anything on ther WEBSITE other than.. they make it

I believe they are using a PowerPC with added instructions.. little red flags should go up with that because.. those added instructions can be anoying problems.

They have 24M of Static ram built in.. I think the processor speed is 200mhz.. a 200mhz PPC = 700mhz Athalon. That doesn't bode well. Especially since we are emulating the hardware for the graphics..


Maybe when we get pentiums going 4ghz?

Actually you start out with your basic PPC instruction set and find out what forces an exception when decoded.
The PPC might be easier to decode than most CPU's I don't know but IBM probably has the opcode map on the WEB site somewhere. I would start with that. I expect implementing illegal opcode exception handling will find the opcodes that are NEW
In all likely hood those are relating to 3d geometry transformations and other useful 3d primitives possibly some audio type things but if there is a DSP I suspect that will handle the bulk of the audio fun. IE MP3 decoding ET AL.

not to put you down or anything, lightknight, but i don't think anybody is going to take you seriously. the best thing to do, if you are going to take it seriously, is to get yourself some VERY GOOD programmers (u will need to show them ur work for them to work with you), and stay quiet for about a year. In that time, you should have had enough time to start the very basics of emulating a part of the gamecube.

just a little word of advice

[gokuss4]

well i heard that the gamecube is less complicating than the N64 which i think is a little true.
