Just to close this question that wasn't entirely answered 10 years ago, and to help people who have this question, the PlayStation 1 can be overclocked.
Although, with overclocking any other machine, it's going to become unstable and have heating issues, as well as capability issues with the other devices.
To avoid the game running too fast, we would need a framerate limiter.

It is worth overclocking it, based on the user's opinion. Stating that "since it's old, it has everything weirdly build so its a pain to mess with" is invalid. The PlayStation 1 is like a very simple computer, and I don't even know why age was brought up in 2004 when that was the previous generation console. Anyway, modifying the components would be fairly easy, if you know what you're doing.
Mostly, the RAM would need to be increased before anything else is even thought of, since that's the console's weak spot. I do not recommend overclocking RAM, so if possible, it would need a replacement built from a custom RAM chip designed to fit the PS1 and to emulate the original chip, only more memory.
