Clarification:
DML ONLY works from SD Card/SDHC Card, nothing else, no USB. There won't be a USB version someday.
So Yeah, this "Clarification" is incorrect, crediar was able to do it


What you'll need:

• IF YOU WANT TO PLAY FROM SD
• The Latest DIOS-MIOS (Lite) package from here (older versions here).
• DML WAD Creator (for older versions)
• IF YOU WANT TO PLAY FROM USB
• FOR DML and DIOS-MIOS
• GameCube ISO Compress, fstfix, DiscEX or GCReEX (your choice, read below first and decide what you want to use)
• A WAD Manager (for example WAD Manager 1.7)
• A SD Card or a USB Device (D'OH!)
• Gamecube Controller and Memory Card

How to:

1. If you have downloaded the newer version go to step 6, if you picked the older ones follow this.
2. Extract the DML package in a folder with the same name as the package (for example DMLr13 for DMLr13.zip). If there is just a iosmodule.elf of the latest DML available then copy it into a new DML folder and rename it to DML.elf.
3. If you already have a RVL-mios-v10.wad, copy it into the DML folder. Then the creator don't need to download the file.
4. Extract the DML WAD Creator into the DML folder. Then run the "create_wad.bat" and type "DML" to create the DML wad, if you don't have the RVL-mios-v10.wad it will be downloaded.
5. If the DML WAD Creator asks you which version you want to build type it in like '13' for DMLr13.
6. Now let's convert some gamecube games! If you downloaded the new DML versions or DIOS-MIOS just start reading here.
7. You'll need the gamecube games in iso or gcm format.
8. If you want to use DiscEX and downloaded the older DML versions, the DiscEX files needs to be in the same folder as the DML WAD creator. Just open the WAD Creator, type "C" to enter the convert menu, drag and drop the game into it and say if you want to compress it or not. If you use the newer DML versions or DIOS-MIOS, open up a command prompt and enter "DiscEX -c gamename.iso" if you want compression, replace "gamename" with the name of your iso file. If you dont want compression just drag and drop the iso file into the DiscEX.exe. Mostly compression will work fine, some games need to stay uncompressed, see here.
9. You can also use Gamecube ISO Compressor for the job, easiest way is there to just drag and drop your ISO file into the Compressor exe file. You can also just double click the exe file to see which options you can also use to compress the ISO files, they are more modes in it.
10. If you have downloaded the new DML versions, you can also use GCReEx, there you can use "GCReEx.exe -x game.iso", this will create no new ISO file but a folder which contains the extracted files, this way saves most space on the sd card.
11. There is also the possiblity to use fstfix instead to compress the games, use it like "fstfix game.iso" or "fstfix game.iso t" and drag and drop the resulting new iso in DiscEX. DiscEX will may stop at a certain percentage to copy the game, it will may also say the game is underdumped/overdumped. Both things come because the image haven't got the orignal size anymore, so you can ignore these messages.
12. After using one of the above ways to convert your games, copy the newly created folder of the tool to sd:/games if you want to play from SD and to usb:/games if you want to play from USB.

On your Wii:

1. Install the DML/DIOS-MIOS WAD with a WAD Manager, this will overwrite the current MIOS/cMIOS. Retail gamecube discs will still work since DMLr19. If you had a cMIOS installed before to play disc backups it wont be possible anymore until you re-install the cMIOS which will overwrite DML.
2. You can play the games either with DIOS-MIOS Booter, NeoGamma, postLoader4, Wiiflow, USB Loader GX or Configurable USB Loader. Make sure you have a disc inserted, otherwise your Wii will simply reset if you try to play a game.
3. The easiest one is DIOS-MIOS Booter, it works with all DML and DIOS-MIOS versions, just start it, select the game you want, set new options with the B button if you want, and launch the game.
4. To boot games using Wiiflow switch the coverflow mode to the gameube coverflow mode by pressing the icon down-right near the home icon a few times until you see the games. You can also download covers for them in the settings, it's the gear icon down-left. Wiiflow also supports all DML and DIOS-MIOS versions with all options.
5. To boot games using postLoader just press home to enter the menu, select "Switch to Game mode". In game mode just press up on the wiimote to enter the DML menu or press home, select "Game options" and then "Show DML menu". Then select the game you want to play.
6. For USB Loader GX you just need to go to the display icon and select display gamecube games too, then you can set options in the menu and play them.
7. In Configurable USB Loader they are just displayed together with the other wii games, there you can also set the options and launch them.
8. The other ways described now are currently not optimized for the new DML versions, doesnt work with DIOS-MIOS and my not work properly.
9. To boot games using NeoGamma go down to "Load Games from: " and select "Load GC Games via DML". Then go up and press A to search games. Select the game you want to play and press A to start it. NeoGamma doesnt have options to set for DML because its made for old DML versions.
10. If you want to remove DML/DIOS-MIOS again either reinstall a cMIOS or the RVL-mios-v10.wad. If DML doesn't work for you make sure you have a clean BC, to get it run the "create_wad.bat" in the DML wad creator package again and type "BC". Then just install the RVL-BC-v6.wad on your wii and try it again.

Recommendations:

• Format your SD Card to FAT16/FAT32 with 64KB cluster size to increase game speed
• If you want to use DIOS-MIOS format it to FAT32 with 32KB cluster size, also make the FAT32 the first one, primary and active
• If you want to use DML r21 I suggest the debug version since the regular version got small problems. Delete the DML.elf, rename the DMLdebug.elf to DML.elf and then create a new wad with it.
• If you have a problem you can try to rename/delete the "saves" folder on your sd card to everything you want, that can may fix it.
• Crediar created a small FAQ here that might help you as well with some general questions.

If you want to know game compatility check out the compatility list here:

Don't forget to add the games you play to the list if they are missing

That's it! If you have questions just ask here. Have fun playing your gamecube games from SD!

The new error happens before I reach the "new game/load game" screen. Also I converted the game file by just typing in game.iso. Should I have used gcreex? As for DML version it is either 2.0 or 2.2
Also I tried both with a disc in and without

It's probably 2.0 of those two because you had the "DML installed version" set to v1.2 -> v2.1 and it would do even less if that option was wrong.
You put the game file in right. It's recommended to do it that way and make sure it's working fine that way BEFORE trying to do it any other way that's faster or smaller (Like GCReEx)

I think my only other suggestions are you might check to be sure no other options got changed accidentally ... and check again if it works in DM(L) Booter still ... and you could always update.
I also have 2.0 installed (but that doesn't mean much because I don't have that particular game) ... have you tried with any other games? ... have you tested it more than once?

Correction : you must have another version installed because v2.0 only exists in the USB version (DM). The SD version (DML) jumped right from version 1.5 to 2.2.
EDIT : even though the setting says 1.2 to 2.1, I think the setting will still work for anything from 1.5 down to 1.0 and and old DML after r52 (v1.0 and up had some random compatibility issues with some SD cards so there's a SLIGHT possibility it's that but I would think there'd be bigger problems than this.)

Sorry, I'm kinda running out of things that are normally wrong. I hope we can figure this out.

 

[michaelcr]

Then it I probably 2.2. And also I had pokemon xD and it worked fine from sd card. Also one weird thing is that in USB loader gx I have it set to tell me gameplay count and it hasn't changed from 0 even thought I have tried playing it. The games settings in USB loader gx reset to default each time I check, I know I have changed and saved though. This is all really confusing since the Dml compatibility guide said that final fantasy crystal chronicles worked with 1.4b.
Never mind it isn't 2.2 its 1.5

 

[michaelcr]

If all else fails maybe I could try using DM with my external hd because I think the dump is ok and that maybe it has something to do with sd card or DML compatibility

 

[Maxternal]

Could work ... could still try updating your DML to 2.3 first and see if that helps.

EDIT : Either one you change to, you will need to either change the "DML installed version" setting OR update GX to r1202.

 

[michaelcr]

Never mind I got it to work haha all I had to do was force NTSC lol!

 

[Maxternal]

Glad to hear ... that's a relief.

 

[michaelcr]

Ya thank you so much for all your help!!!!! I never would have figured it out on my own!

 

[michaelcr]

Ugh nevermind the error still appears... Just I am able to start playing before it appears now....

If a video option change helped last time, maybe try all the other video options.

 

[michaelcr]

This may sound dumb but I was able to save a game to the memory card.... The first dump I had didn't have the "an error has occurred" screen it only had green screen at intro.... Would it be possible for the first dump to work if it doesn't go to intro?

It's possible. Also, a green screen often indicates a video format error so the forcing NTSC could fix that dump too. (Anything's worth a shot at this point.)

 

[michaelcr]

Ok I am gonna try to use dios mios now... Any tips on what all I need to download?

 

[Maxternal]

Any tips on what all I need to download?

Just the WAD to install it and the latest GX version
http://www.mediafire.com/?1voyas284vs6qiv
to make sure it's compatible.
Otherwise everything is basically the same as going off of SD as long as you format your HDD right.

 

[michaelcr]

I'm attempting to partition my external hdd with easeUS partition master and the format I want is fat32 32k cluster right?

Yes, and make sure the partition is the first one and that it's primary and it should work fine.
(There are some other minor details and exceptions but they're extremely rare.)

 

[michaelcr]

Does partitioning take a long time because when I try to apply partition it stops at 27%

If you are resizing partitions it can take quite a while.
If you're creating a partition in empty space it should be pretty much instant.
Formatting the partition once created can also be either instant or take a while depending on what method used and the size.

 

[michaelcr]

When I download the dios mios where do I put the source folder

 

[Maxternal]

The source is just for programmers to look at. All you need is the WAD file.

 

[michaelcr]

If the game doesn't work with dios mios I will try downloading it again... Is downloading the ROM the same as downloading gcm?
