It's already been confirmed its a heat issue that messes up the solder. Why argue this?
How showing warning will help? By design Sony put the two most hot objects on the motherboard too close which in a sense is the reason why gets so hot. If this was enabled it would've spam you constantly, cause i believe the PS3 normally without gaming runs at 80-90C.
Don't expect it, realistically most games out there can be pirated... psp/xbox/DS/wii their not hard to mod, or that secret so they can always make a claim that its piracy.
I always thought devs somewhat like piracy, how hard is it to blame piracy for low sales? in the end, we will just get punished and it will evolve into either pirates or idiots lol... I dont support piracy that much, but I got nothing against either. its not like ps3 users got anything for being pirate free for years =\ so what did we lose? thats right, nothing lol.
I've seen this message before on other consoles. You won't see this message unless the PS3 is seriously overheating. If you block the console vents to increase heat, you will see this message display eventually.
Honestly, by the time you see this message your PS3 is already way too hot. If you have the PS3 properly ventilated in an open area, it should never get too hot.
