Still nothing with r30 (made it with v7 of Joostin's wad creator and the .elf from the google code).
Tested in main nand on neogamma. Oh, and that cache file in the root of the SD file was removed.
Some questions for those that got it to work:
-how did you put the games on the SD card? (discex? discex -c? that shrinkfix-thing?)
Discex.exe -c -a isoname.iso in a folder named games in the SD root. discex -c -a have worked better for me than just discex -c or discex.
-what loader(s) did you use? (I see wiiflow thus far...anything else?)
Wiiflow-mod and Neogamma r56. (if wiiflow is used make sure delete the cache file in your USB or SD whatever you are using to launch wiiflow as usb or sd/wiiflow/cache/lists/sd_games.db so wiiflow can refresh the games list, otherwise if you try to run a game that is not longer in your sd your wii will turn off).
-what's the exact size of the wad file? (if you know how, please add CRC32 and/or MD5 checks)
For r30 200KB(204,800 bytes) size on disc
-how did you obtain that wad file?
Take the DMLr27.zip or DMLr26.zip posted by FIX94 in the page 80 thru 88 (I do not exactly recall it), create a folder named DMLr30, put all the zip file r26 or r27, DML_create_wad_v0.5.zip, RVL-mios-v10.wad and the DMLr30.elf into the folder you created. next extract all the zip files to the root of the folder, Then delete the DML.elf and rename the DMLr30.elf to DML.elf, click on create_wad.bat, a cmd window will appear just press enter and wait until the file is completed you will see a new file named DMLr30[MIOS-v10].wad, copy it to the SD and use a Wad mannger to install it (I use Wadmanager), run your preferred launcher with DML support, finally enjoy it.
-what format SD card were you using? (32 or 64k clustersize?)
SDHC 32GB and 16GB Class 10, 64k clustersize
I'm not that bothered that I get black screens...It's that it almost seems to work randomly for people. That's pretty weird.
