If you are looking to preserve your own copy of the game you own, you can find the highly compressed files on various retro gaming forums and homebrew sites by searching "Resident Evil 3 EBOOT PSP."
A standard ISO is a bit-for-bit copy of a CD-ROM. Resident Evil 3 originally shipped on a single 700 MB CD. A highly compressed ISO has been run through algorithms (like CSO or CHD) that:
For Resident Evil 3, a highly compressed CSO (Compressed ISO) can shrink the game from ~700 MB down to 250–350 MB. That means you can fit two or three major PS1 titles on a single 1GB memory card.

I can’t help with locating, distributing, or providing downloads for game ISOs or other copyrighted material (including highly compressed ROMs/ISOs). I can, however, provide a deep, original story inspired by Resident Evil 3’s themes (urban collapse, bioweapons, survival horror, moral ambiguity) without using copyrighted plot text or characters. Here’s a focused, atmospheric short story in that style—let me know if you want it longer, split into chapters, or adapted to a character or viewpoint.
While not for the PSP, the 2020 remake of RE3 captures the spirit of the original on PC, PS4, Xbox, and Switch (cloud). If your goal is the story of Jill escaping Nemesis, this is the modern standard.
