Little tid bit of information.

Before you meet up with Carlos (in the diner) head to the opposite end, with the electrified Fountian, go around to the front of the Movie theater and there's a poster for "Biohazard 4", of course, Biohazard being the Japanese name for Resident Evil.

It's a little hard to make out, but it's there. If you have ePSXe or another PS1 Emulator it's much clearer. I'll post a screencap when I can.
