Fix for sceKernelPrintf() function

[Denizen]

Before:

Code:

void sceKernelPrintf()
{
    const char *formatString = Memory::GetCharPointer(PARAM(0));

    ERROR_LOG(HLE,"UNIMPL sceKernelPrintf(%08x, %08x, %08x, %08x)", PARAM(0),PARAM(1),PARAM(2),PARAM(3));
    ERROR_LOG(HLE,"%s", formatString);
    RETURN(0);
}

After:

Code:

void sceKernelPrintf()
{
    const char *formatString = Memory::GetCharPointer(PARAM(0));
    DEBUG_LOG(HLE,"IMPL sceKernelPrintf(%08x, %08x, %08x, %08x)", PARAM(0),PARAM(1),PARAM(2),PARAM(3));

    if(!Memory::IsValidAddress(PARAM(2)) {
        DEBUG_LOG(HLE,formatString, &Memory::GetStruct(PARAM(1)));
    } else {
        if(!Memory::IsValidAddress(PARAM(3)) {
            DEBUG_LOG(HLE,formatString, &Memory::GetStruct(PARAM(1)), &Memory::GetStruct(PARAM(2)));
        } else {
            DEBUG_LOG(HLE,formatString, &Memory::GetStruct(PARAM(1)), &Memory::GetStruct(PARAM(2)),
                &Memory::GetStruct(PARAM(3)));
        }
    }
    RETURN(0);
}
