Hacking Creating a DIOS MIOS Booter channel forwarder using CustomizeMii

[cmann1]

How would you make a channel forwarder for DM Booter? I have created one using CustomizeMii which partially works, it shows in the system menu and it loads DM Booter but DM Booter does not detect DIOS MIOS.
If I load DM Booter through the Home Brew Channel it works fine though.

You probably miss the AHPROT patch.
You need to edit the channel tmd manually to grant hardware accesses to the launched homebrew. It's used to access NAND to read and detect the installed MIOS.

At 0x1d8 replace the hex value with 00000003

I didn't see how to replace the tmd in customizeMii.
Maybe you can use another wad editor/creator.

Edit:
Check this tool (require python):

OK so now I have used ShowMiiWad to unpack the wad I created with CustomizeMi, and I have opened the file called 00010001444d4246.tmd in a hex editor.
Do I need to replace only the one byte at 0x1d8 with 03 or do I need to replace the 4 bytes starting at 0x1d8with 00 00 00 03?

replace the four bytes.
I think only the 03 is important (it sets two flags in binary: 0011), I suppose the other are always set to 0x00 anyway, so just change 0x1db to 0x03

Look here for the tmd format.

OK thanks I'll try it out.

UPDATE :
At the top it still shows DIOS MIOS (Lite) not found but the games do run.

I have one other question: When loading DM Booter through the channel some text flashes on screen just before it loads which doesn't appear when running it through the home brew channel, it doesn't stay for long but it says something about allocating memory and there seems to be some kind of progress bar.
Does anyone know what it's for and why it would show up?
