Duo Q users? Anyone else have this problem?

Yes, it appears to be the case. Or, it could be the oscillator is at a slightly larger/smaller freq then is required (or some other hardware limitation that is not known to me). When removing something like a routine to display a picture/message, it would likely be a trivial trap instruction to plot color points to the screen in an iterative manor. I find it odd that they could have mistaken compatibility routines (what ever this case may be), for these plot op codes (which *should* be simple MIPS instructions).

But nothing is impossible, I suppose. HA, someone should tell them. I was not a happy camper with this chip. But it could have easily been avoided if they simply said: Works with rev A,B of NTSC, only.. not on DOL-101 with no digital out... the case would have been closed, I would not have ordered it. Instead they, incorrectly, generalize by claiming complete compatibility. :/

 

Okay, DOL-101.. here's the thing. DOL-101 units use the revised bios which gives the disc exactly 12 seconds to have fully spun up and be recognized. Cheap media and if it's a big disc also will probably not make it in time and therefor will not work.

This is the same for XenoGC or DuoQ. This comes from the XenoGC author himself.

 

Is there a multi ISO creation tool (multiple games on one disk) that works with the Duo-Q?

Cheers,

Great question! I am also looking for this, if it exists. Anyone?

Maybe there is a third part application that can do this like GCOS (search for the start of the next iso in disc)? Else, maybe, there would have to be a boot instruction in the mbr of the disc, that would have the ability to branch and load the first inst of the diff game images on the disc, chosen, likely, from user input.
There is a utility in the Xbox mod-scene that does just this for your multi game images. I don't use this, however. I just have the games in a folder on the xbox file system called 'Games' and tell the Xbox OS to look in this folder for 'games on Hard drive' via the config file. A little bit of a hack, I know, but it works great!

Something tells me that Nintendo designed their firmware to look up to and including the 1.4gb mark on discs.... Just guessing. If so, there could be a way around this.

 

Well I have tested the Dou-Q with 2 multi-game-disk-tools

"loonycube" and "GCMtool"

Neither would boot with the Duo-Q

Qoob SX boots the "GCMtool" multi-game-disks perfectly

So that's a feature you lose when you buy a $16 modchip.

I also just read a review about the XenoGC chip, apparently it is a wireless chip! It's solder points align perfectly with the points on the board so you just solder directly to the board - no wires... Funky eh? And it's only $5 more than the Duo-Q

So I guess the king of low end is the Xeno and the best chip is the Qoob.

But so far the Duo-Q has worked fine, booting single game disks burned on RitekG05 disks.

Cheers,
Craig

 

The intresting thing is, Team Omega (makers of DuoQ) claim it will work with multi-game discs (checked on their site). But, they also claim 100% compatibility with all game cube versions :/

I am thinking this might have something to do with loading the different QOOB BIOS, while duoQ/Xeno uses the original on board Nintendo BIOS.

Yes, I saw that Xeno is wireless. However, I would probably use wires, if it made sense to. It seems like a board soldered to another board is a odd way to go. I would have to see it in person to decide.

I am also using Ritek G05 and they work great. I googled for the best price and swung under 20c USD, including shipping Also, I have used some PRODISCF01. TY03 are not working for me (Taiyo Yuden, or whatever they are called). But keep in mind nothing booted until the board swap.

I should have gotten a Xeno... (Qoob seems like paying for some features I would not use).

 

I know the Qoob cost more but it pays for itself if you are *aquiring* lots of games, simply with the price of media and the convinience of less space taken - many games are 30mb, 100mb, 300mb, 600mb, and so on.

I have some multi disks with as many as 6 games on them. I wouldn't give away the ability to boot multi-game-disks for $20 or even $30, but that's just me.

Either way, a modded cube is groovy

Happy gaming,
Craig

 

emu_kidid? You wouldn't happen to be the emu_kidid that develops GCOS, would you? If so, I'd just like to compliment you on the excellent work you've done. I'm really looking forward to using the latest version on my qoob Pro once it's stable

Anyway, back on topic. Yes, the XenoGC is wireless. Not like that makes things any easier, especially if you don't have a soldering iron with a very pointy tip. Also, you can't use multi-game discs on it either. The problem is that the XenoGC and DuoQ don't have a file manager implemented whereas GCOS, ViperGC BIOS, and qoob BIOS do.

 

Oh, sorry! I missed your message earlier. This means that either will have a similar issue on DOL-101, and this timer problem explains why some had success with smaller media. So I guess it *could* work on all systems provided you use mini-media, right? It is all clearer with all your help. Thanks all!

You're a GC HomeBrew developer?, Cool, I have been meaning to try out some simple console apps/games. Just wondering, but, are you using GCC for mips instruction set (standard mips, patched or something), or are you just writing straight up op-code/MIPS assembly to develop (GameCube is a MIPS inst set, isn't it)? Just curious.. I am into embedded systems stuff. It would be fun for me to play around in But I was hoping people were at least using a high level language lol... but if not it's all good, I guess.

I was going to load GCOS through on a standard DVD, padded of course, to 1.4gb. That should do it, right? I was wondering though, does the GCOS do something with multi-game disc booting?.. If so I am in business!

So, has anyone gotten multi-game discs to boot on DuoQ or XenoGC since, I think, they both seem to claim this functionality (or maybe they mean multi disc games..?, but in that case, who would care lol).

 

yep i'm the same emu_kidid from GCoS.

Xeno,DuoQ both claim multi-game Discs to work, but they mean they will work through the use of something like GCoS.

I wouldn't waste a DVD-R on GCoS 1.5, I would wait till GCoS 1.X is released. It will work with XenoGC and DuoQ and multigame etc.

 

Cool. I guess I will wait for the new version. Do you own/work on the site: http://www.gamecubeos.com ? It does not look like you want to talk about the development stuff, so I will check out your source and examples on there. Sorry if I was bothering. Looks like fun stuff.

 

Yes www.gamecubeos.com is moderated by me, but I don't find the time to update it these days and I find forums alot more interactive with response.

 

[Edit]

Playing with source code now

Fun fun!

Wow, it uses some good stuff from linux project, too.
