Hacking Devolution - Public Release

[sjones900]

Oh man, this is really great. I'm sure I'm a little late to get all giddy about this, but whatevs. I really don't have much use for devolution since my wii has a mod chip and I can play GameCube game just fine off an SD. But I would really like to see GameCube functionality expanded through this to feature sonething like classic controller support. Good work! Keep it up.

 

[Maxternal]

I have a technical question, something I'm curious about... does Devolution work by mapping GC syscalls to their Wii equivalents, providing polyfills where necessary? If that is the case, could it be built upon to load Wii games the same way, without requiring cIOS to be installed?

Devolution has all of MEM2 to use for itself since it didn't exist on the gamecube, it would be a lot harder to do the same thing for wii games because they use that memory.

Yeah, that makes sense, it would have been cool though (what with cIOSes being evil and everything).

So no hope for Devolution = Wii360 = WiiS3 then ?
Oh well.
Maybe just for GC games, then (although I'm sure even then it would be a pain to map and patch every single GPU call from one console to another. The only thing they have ROUGHLY in common is the PowerPC proc.)

Sounds like a good plan... if you want to see 360/PS3 games running at 2 frames per second. The Wii is pretty much a Gamecube with extra cheese....

Actually, I what I was mentioning was the other way around, port Devolution to PS3 and to X-Box 360 to be able to play GC (If not Wii) on those consoles. (I don't know how well their disk drives would do, though, with the little GC disks.)

 

[wiismodrome]

Oh... that might even be possible, given the available processing power... but I don't know enough about the architectural differences to speculate.

Hope Wiimote support gets added soon, it would be awesome to play Melee with a D pad.

 

[AnthonyRuiz]

yeah i hope too

Hi, Does anyone know how to boot GC games with other loaders? (Cgf, wiiflow, gx), with the .isos within games folder.
For example: usb:\games\GALE01.iso
They do not see the games :/

For the loaders you have to put them in separate folders and name them game.iso (basically the same as for DM(L) loading)
For example: usb:/games/GALE01/game.iso

You're doing it wrong. It needs a folder with the ID (or something similiar) in the games folder and the game in that should be called game.iso. It should look like this:

usb:\ games \ GALE01\game.iso

Edit: Too slow....

I don't know if [member='tueidj'] is planning to include some sort of button binding configuration for that but I would assume that a wiimote support would also include classic controller and/or nunchuck support. I would guess that at least in the default the wiimote d-pad would be the GC controller d-pad so you would only be able to use the d-pad for games where you're already using the GC d-pad.

Buttons settings WOULD be really cool, though. (I'd assume there at least has to be some sort of config to select which wiimote equals which GC controller ... or at least switch between ALL wiimotes and ALL GameCube controllers) It would also be kinda neat if it could use a Wii64 style gyro-to-analog conversion when just the wiimote is on without anything connected.

 

[tmv_josue]

Fuck , I feared that they couldn't.
I expected them recognize the games that way because I wanted to use the sample loader too.
Anyway thanks [member='Maxternal'] and [member='Harsky']

 

[J-Machine]

This loader is amazing! Everything seems to be working fine for me on this end. The main problem I'm having is that after loading a game, and then pressing the power button to return to the homebrew channel, Devolution fails to mount the hard drive. In fact, the only way for me to load another game is to either power down the system, or physically unplug the hard drive. From observing the the lights on my hard drive, it seems that after returning to the homebrew channel via power button, the hard drive is still very much active. I'm not sure if this is a hard drive specific issue, or if its just because Devolution is still early in its development.

Very impressive work indeed! Also, I actually like the AP measures taken. It gives me more reason to be proud of my GameCube collection. Keep up the good work. Now, if I could just find a copy of Fire Emblem at a DECENT price........

My hard drive does not have this problem. maybe yours has trouble being reaccessed.

Mine either.

Thanks again for this loader. I just tried Tiger Woods 2005 again with the new build and here is the log. It still freezes at the loading screen. Its really not that important but wondering if other EA sports game do the same. Great program!

[crono141]

So, seeing memory cards being fixed, I redownloaded devolution from the OP, yet still can't access my first party card. Whats up?

 

[daxtsu]

The new build hasn't been uploaded for public consumption yet. All that's available right now is a precompiled sample loader a few pages back.

 

[squablo]

My hard drive does not have this problem. maybe yours has trouble being reaccessed.

Mine either.

.......As I feared. I'm using a seagate drive. It's a newer drive, and is solid on the wii end of things. I guess I'll tinker with it and see if I can resolve this issue. Is there anyone else having similar issues with seagate drives? Like I posted before, it just seems like the drive is still being accessed by devolution after I exit to the homebrew channel via power button. I have also noticed that verification takes much longer with the hard drive as opposed to the USB flash drive I was using, but that could be a solid state vs optical disk issue.

Any input would be helpful. Thanks in advance.

 

[dronesplitter]

My drive is a seagate free agent go and it doesn't have that issue.

 

[tueidj]

It happens to me sometimes (using a vantec usb hdd adapter) if you press power while the HDD is in the middle of a read. The weird thing is HBC can read the drive perfectly fine after quitting the gamecube game, but if you start any other homebrew app from there it will hang during USB initialization (before it even tries to mount the HDD). At that point IOS has been reloaded at least twice so everything should be in a clean state.

The reason verification takes longer is most likely due to searching for free space to put the .dvv file, if you have a large drive that is fairly full it can take several seconds.
