DesMuMe mods !!!

[NHervé]

Thanks. I'm glad to see people likes my new GUI.

Good news : Rayman Raving Rabbids 2 starts to work !!!
The bug was VERY stupid : opcodes such as OP_STMDA2_W stopped execution. I fixed this, but the 3D core has a bug, it makes the game freezes before displaying the rabbit.

The game runs fine and fastly with DUMMY 3D core.

That code is commented for a good reason: it's unchecked, and it's not meant to be release ready. We know this was there for a long time, but until someone checks those ops properly, it won't be changed, atleast on official CVS: it's only making the interpreter more unstable.

The game seems to be throwing random data/trash to the 3D core, and it fails when some values go seriously out of range. I can't say if it's a bug in the 3D core, or somewhere else, without proper debugging. Don't assume that because it crashes on the 3D core, the bug is there.

Excellent. Don't give up. You are getting there. Keep up the good work!

Thanks alot !

For Rayman, the bug is from NDS_glCallList func : when I disable it, the game works.

Did you read my post? Something is sending trash to the 3D core. I know it's crashing there, I debugged it for curiosity, but you don't know the reason, which is equal to not knowing what the bug is: only where it crashes.

[NHervé]

For Rayman, the bug is from NDS_glLoadMatrix4x4 func : when I disable it, the game works. So there is a matrix problem.

Yes I read your post. I found a matrix problem.

No, you didn't read. AT ALL. It's not a problem with matrices, making a patch there will not fix ANYTHING.

[Normmatt]

If i were to guess i'd say the problem is with OP_STMDA2_W seeing as it stores data, and if its storing it incorrectly (which is probably the reason it stopped emulation) then it could be the cause of your so called matrix problem.

[NHervé]

This is not a matrix problem. It's another thing.

I told you :P

[refraction]

i think a parrot has taken over NHervé's computer to try and make him look like he knows what hes doing

No offence NHervé, i know this isnt your area of expertese at the minute and you are trying, but the bugs youve found so far have either

a. already been fixed.
or
b. youve given clues on whats happening, then shash fixes it :P

while its nice you are helping and all this fix0ring is great, i think you n shash should take it to PM's or smth rather than on the forums, cos you are emitting newb rays!

[ShakirMole]

lols to refraction
NHerve is still learning so let him prove himself as he has done so for DeSmuME and besides he has done well for the PS2 plugin

[refraction]

oh i know hes still learning, and i think its great! but by saying hes finding all these problems without actually knowing, then shash corrects him (which i can tell is driving him a bit loopy lol), it serves no purpose than showing himself up, which is why i suggested while hes still getting to grips with it, if he has anything to report, keep it to PM's then he doesnt look like a 'wannabe' on the forums. Im not saying it to spite, im saying it to help him save face ;p

[NHervé]

Yes. When I asked "how to create pcsx2 plugins", some guys answered me "if you have to ask you can't", and I've released Megapad.

well thats cos they have a defeatest attitude. Im not saying if you dont know you never will, i realise you are learning and willing to learn, which is the most important thing.

Great works NHervé go on...

[NHervé]

thanks. The 3d rendering is damn buggy, I've hacked the 3d core to get it, but I'll have to hack better. It seems the game is sending garbage or badly-formated commands to the 3d core.

It's the CPU fault, the 3D core works quite flawlessly. Saying the 3D core is the culprit is utter nonsense, atleast on Rayman2 context. Oh, and PLEASE, don't make me elaborate why you're wrong on this, I'm not willing to write a 2 page explanation about why it's not the 3D core: I basically know way better how desmume, the 3D core, and the usual bugs are, that's why I'm saying this.

[NHervé]

Guess what ??? I fixed the bug ! It was quite stupid : when command is 0, the variable that contained the commands was not shifted of 8 as it should do. I fixed this in 3 seconds and now the 3d rendering is correct.
