DIOS MIOS v2.10

Post by actarus1973 »

Automatically translated from French.

2026 update: this topic dates from 2012 and the tools have changed since. The up-to-date method is in our tutorial GameCube games on Wii and Wii U: Nintendont, the successor to DIOS MIOS.

Image unavailable (removed by its host)
We were all waiting for it, Crediar finally published it.
Here is the new DIOS MIOS that will allow you to run your GameCube games from a USB device.
The USB device must be formatted in FAT32 with cluster sizes of 32KB maximum on an active primary partition.

Features:
Fast loading from a USB device
Loads compressed or uncompressed Gamecube ISOs
Loads Gamecube discs
Emulates memory cards (NoMoreMemory)
Cheat codes support
USBGecko debugging
Configuration of different parameters
Reset / power off (R + Z + Start) (R + Z + B + D-Pad Down)
Support for Real-NAND and Emu-NAND
Screenshots in-game (R + Z on the 4th controller)
Support for two-disc games

What DIOS MIOS doesn't do:
Play games from the SD, you need DML for that.
Play games on burned discs
Audio playback via disc audio streaming
The cafe

Changelog:
[tabs:2.10]*Fixed a bug in the pattern detection code (DVDLowReadDiskID)
[tabs:2.9]*Changed patch code to prevent false hits (DVDLowReadDiskID)
*Added C_MTXLightPerspective patching (Fixes heat effects when using wide screen hack in Zelda:WW)
[tabs:2.8]*Fixed a bug in GCLoader that broke the progressive patch
*Moved progressive patch back 16 bytes, this fixes PADHOOK and progressive patching not working at the same time

Thanks to FIX94 who sacrificed his school career for testing this release!
[tabs:2.7]*Fixed a bug that caused a black screen when using PADHook and Progressive mode patching at the same time
[tabs:2.6]*Reduced HDD read time out to 25 seconds
*Added two disc feature (Extracted format is unsupported)
Use the latest DMToolBox (0.3 or higher) to install your two disc games

This will be the last version for some time, since I'm moving my focus to other
things.

Always remember; Impossible is nothing!
[tabs:2.5]
*Fixed a bug in DM that could cause a fatal read error when using devices with
under 8GB size
*Added a PADHOOK pattern for Batman:Vengeance
*Added a screenshot feature
This feature can be enabled/disabled via the DM(L) config
Press R+Z on the fourth controller to take a screenshot any time!
Screenshots will be saved to device:/screenshots in the YPbPr format, you can
use my tool to convert them.
[tabs:2.4](2012-10-21)
Fixed NMM for Mario Kart Double Dash. Saving ghost data works now as well
Fixed a bug that would sometimes break cheating/debugging unless both were enabled

*Removed unused files
[tabs:2.2](2012-07-20)
Added a new DVDLowRead pattern (fixes Luigi's Mansion USA and maybe other games)

(2012-07-18)
Added code to prevent drives going into sleep mode
Fixed a bug which ignored the DML_CFG_PADHOOK setting and always patched PADHOOK (fixes PSO1&2)

Well I'm going to test V2 with USB to see what happens, WiiGX say this

Only the latest version of DML Booter (developed by FIX94) is suited for now.

Well after testing with only DML Booter, it's not great :( it didn't recognize my games on USB (empty list) I reinstalled r59 (full list) reinstalled V2 (I see my list of games) so either the games don't launch or it launches the GameCube game that's in the drive :s (that's fishy right?) maybe it's because my hard drive isn't in max 32K clusters.

Re V2 Update 2 works wonderfully for me now with the few games I have on my hard drive

I just changed one thing in the options
Before launching the game, press B button to enter the options
Then select "boot methode <<< new >>>"
Press the R button to go to page 3
Then check if "No Disc Patch" is set to <<< on >>>
Go back to the game list by pressing B and launch your game

For me it works so I don't know why it wouldn't for you, keep us posted.

And after doing that, even if I set it to Off my games work, weird but I'm too happy about it.

Edit: Mario Power Tennis still doesn't work with 3c, there you go.

I have a question, I tried the NMM option but it doesn't work with all games (ex: Megaman Collection) it stays stuck at loading the card in slot A, but is there a trick to make it work properly? or transfer a save from the GC memory card to the SD card.

I bet! adding a whole usb support to something that doesn't have any, that must be quite something!! to think that so many years after preloader it's come to this, it's really beautiful!! who would have thought a super new awesome thing on wii in 2012 :lol:

Still no Mario Power Tennis for me whether in PAL or NTSC, SD or USB :( yet it's stated as compatible on the compatibility lists

https://wiki.gbatemp.net/wiki/DIOS_MIOS ... ility_List
https://wiki.gbatemp.net/wiki/DIOS_MIOS ... ity_List#A

EDIT: Mario Power Tennis (USA) works with Dios Mios Lite r58 and Dios Mios V2 Update 4
but still not on USB with Dios Mios V2 Update 4

A question is it possible to have both Dios Mios Lite r58 and Dios Mios V2 Update 4 coexist, in order to have more compatibility?

Mario Power Tennis PAL Version works fine for me with a particular little setting.

With DIOS-MIOS Booter: Video Mode => PAL60
With WiiFLow in the game settings: Video Mode => 480i PAL

Ok, I really don't understand what's going on, it still shows "Fatal error entrypoint is not within MEM1!" and that's with any video config, so I have DIOS MIOS 2 Update 5 and DIOS MIOS Booter r27 and the latest USB Loader GX to date.

A bit of reading.

Basically, redo your dump.

Ok, thank you ;) I'll test it and edit my message once I've done it and if it works.

Edit: there you go, so I redid a dump of my original game, same problem, and yet it works when I launch it from the drive, so I ran the iso through Gamecube ISO Tool and now it works, so my original game works in the drive but is no longer good for making a dump, thank you for helping me ;)

thanks. By the way for DM fans, which backup format do you prefer? iso? gcm? raw or shrunk? Is GCRex essential or do you also get good results with a 1:1 iso (made with clean rip for example).

And I was wondering if the loaders (wiiflow especially) could use the dios mios installed in sneek's emulated nand? in order to be able to play multigame discs while keeping a cmios since dios mios can't read multidiscs. thanks for your insight;)

Personally I use the isos compressed with discEX.
I see no point in using GCRex, the extracted files will take up more disk space with 32 or 64k clusters.
No possibility to play GC games on emulated nand with WiiFlow as far as I know.
