Please describe the issue you're having

to select another partition, I get error I have seen in the src read
another partition that needs to change from primary to secondary harcodes
fix it and so are hardcoded?

Please provide any additional information below.

You could add a switch partitions

I tried but I find myself with the c # cpp not step

Support for additional partition types (secondary, tertiary, quaternary) | Fix
hardcoded values

 Offset = Descriptor.Tertiary_Offset << 2;
        Out->Print("Partition Info is at: 0x%x\n", Offset);

        // TODO: Support for additional partition types (secondary, tertiary,
quaternary) | Fix hardcoded values
        dword BufferLen = (Descriptor.Tertiary_Count / 4 + 1) * 0x20;
        byte *PartBuffer = (byte*)memalign(0x20, BufferLen);

        memset(PartBuffer, 0, BufferLen);
        DI->Read_Unencrypted(PartBuffer, BufferLen, Offset);

        Wii_Disc::Partition_Info *Partitions = (Wii_Disc::Partition_Info*)PartBuffer;

        for (dword i = 0; i < Descriptor.Tertiary_Count; i++)

I'm doing wrong?

We'll implement that soon.

In this loop is selected which partition is loaded:

        for (dword i = 0; i < Descriptor.Primary_Count; i++)
        {
            Out->Print("Found Partition (Type %u): 0x%x\n", Partitions[i].Type,
Partitions[i].Offset << 2);

            if (Partitions[i].Type == 0)
            {
                memcpy(&Partition_Info, &Partitions[i], sizeof(Wii_Disc::Partition_Info));
                break;
            }
        }

Now it loads the first partition which has .Type = 0

Sorry, i had a closer look at this now. It's more complicated than i thought. I 
don't
understand this, so what i write here are only suggestions.

dword BufferLen = (Descriptor.Primary_Count / 4 + 1) * 0x20;
needs to be changed, that all partitions are read, so you need .Primary_Count,
.Secondary_Count, .Tertiary_Count and .Quaternary_Count. But i don't know how 
exactly
this has to be done

for (dword i = 0; i < Descriptor.Primary_Count; i++)
i guess this needs to be changed to:
for (dword i = 0; i <
(Descriptor.Primary_Count+Descriptor.Secondary_Count+Descriptor.Tertiary_Count+D
escriptor.Quaternary_Count;
i++)

And you would need to change the loop, in order that you can select the 
partition to load

'In' was not declared in this scope

In variable like?

Please, we will work on that, if you have suggestions come to the IRC 
(#SoftChip on
freenode), don't post them here.

r78 can load multi-partition games, I think that's what you need, and not the
secondary, tertiary things. I'm working on a way to choose what partition to 
load now.

That's a cIOS problem, I'll implement the possibility to choose the Boot 
Partition,
but for now, this issue is solved.
