You know I been thinking of a solution for the 2-disk games for DML, this may sound very stupid since I'm not technical "enough" for this so please be easy on me and hear me out!
Now we all know the only reason why they broke games into two disks back in the days was because of space limitations, now with DML we don't have this issue anymore, so why not create a program that can combine BOTH disks into one? Something like this:
1-Start .exe program
2-Select DISK 1
3-Select DISK 2
4-Create new .iso
The .exe program adds a feature in which during gameplay if you press a certain combination of keys a menu pops up asking you to choose a disk like this :
Choose Disk:
-Disk A
-Disk B
Then convert the new .iso into DML format, when running the game on Wii you get the same menu that asks you to choose which disk you wanna play at the beginning, select which disk you wanna start then start the game, during the gameplay when you're being asked to swap disks simply press that combination of keys to call for that menu to pop up again and then select the other disk!
I know it's not easy to create this but I think it can work!
As for the games with audio streaming issues, why not do something similar? A .exe program that can convert these audio files into a format that is easy for DML to detect? Would this work?
Old DiscEx format is still supported.
The New format pretty much takes less space than an ISO. But that's your choice.
Hey that's awesome, in this case If they retain the ability to run disks and confirm it's working with all games that used to work with the old one, I might give this new DML a try!
