If you don’t own a PSP, the highly compressed patched ISO is also perfect for emulation.
For the archivist and modder, here are the hard specs you should expect from a genuine “highly compressed patched” file:
| Specification | Details | |---------------|---------| | Original Name | Midnight Club 3: DUB Edition Remix (USA) | | Compressed Size | ~380 MB – 450 MB (ZIP/RAR) | | Extracted Size | ~1.2 GB (using CSO level 9 compression) | | Region | USA (NTSC) – Works on all region PSPs via CFW | | Game ID | ULUS-10041 | | Firmware Required | 5.50 GEN-D3 or higher (Patched for 6.60+) | | Format | ISO (sometimes .CSO for extra compression) |
Solution: Your highly compressed file may have been downloaded incompletely. Check the file size. If it’s below 350MB, re-download it. Some compression algorithms are too aggressive; look for a version labeled CSO level 1, which is less compressed but more stable. If you don’t own a PSP, the highly
Step 1: Extract the Archive
After downloading the Midnight_Club_3_DUB_Edition_Remix_Patched.7z file, right-click and extract it. Do not run the ISO from inside the zip. You should see a .ISO or .CSO file.
Step 2: Connect Your PSP
Turn on your PSP, navigate to Settings > USB Connection, or use a card reader. Your computer will show the PSP drive (e.g., E:\).
Step 3: Navigate to the ISO Folder
Inside the root of your PSP Memory Stick, look for a folder named ISO. If it doesn’t exist, create it (all caps: ISO). A highly compressed version uses advanced algorithms (like
Step 4: Copy the File
Drag the extracted Midnight_Club_3.iso or .cso file directly into the ISO folder.
Step 5: Disconnect and Play
Press Home on your PSP, exit USB mode. Go to the Game menu and then Memory Stick. The Midnight Club 3 icon should appear. Launch it. The patched version should bypass the classic freeze and boot directly to the DUB intro.
The original Midnight Club 3: DUB Edition Remix ISO file size is roughly 1.6 GB to 1.7 GB. This presents a problem: but the core experience—the cars
A highly compressed version uses advanced algorithms (like CSO compression or specialized repacking) to shrink the file size without deleting gameplay content. Audio might be slightly downsampled (imperceptibly) or dummy files removed, but the core experience—the cars, the cities, the music—remains intact.
Solution: This is a known PPSSPP bug. Go to Settings > Tools > Developer Tools > Renderer and switch from Skip Buffer Effects to Simulate Block Transfer. Restart the game.
Even a “highly compressed patched” version can run into hiccups. Here are fixes to the most common complaints:
