I found 1 bug:
u32 stringcompare(char *s1, char *s2)
{
u32 index = 0;
while (true)
{
if (s1[index] == 0 || s2[index] == 0)
{
return 0;
}
if (s1[index] != '?' && s2[index] != '?' && toupper((u8)s1[index]) != toupper((u8)s2[index]))
{
return index;
}
index++;
}
}
If the 1st character doesn't match it also returns 0, i return 1 there now. That explains why M booted the other .dol. Well, the code should fall back to main.dol if there are 2 matches, which means it doesn't have a M1.dol in the list it looks in. And that doesn't make sense, NeoGamma uses the very same code for disc and disc+, it gets the .dol name in both cases and then searches its offset.
PS: If you want to, you don't have to, you can try "?1" but i doubt it changes anything
PPS: Sorry i'm tired but i think this bug might be the bug here, and "?1" should work as tempory fix
