How to keep Torpedo Event Camera open until detonated or reached max range?

[forhotc]

Hi there, I'm just wondering in SH4, is there any way (like editing some config/game file) to keep the Torpedo Event Camera open until detonated or reached maximum range?

I always like to fire torpedoes from a very long range (in both SH3 and SH4), but the event camera is always closed before I can see the results.

Thanks in advance.
