The PlayStation (PS1) and PlayStation 2 (PS2) represent the golden era of console gaming. From Final Fantasy VII to Shadow of the Colossus, these libraries are vast—but so are their file sizes. A standard PS2 DVD holds 4.7GB of data, and a dual-layer disc hits 8.5GB. Multiply that by a library of 3,800+ titles, and you are looking at terabytes of storage.
Enter the world of "Highly Compressed" ROMs. For users with limited hard drive space, slow internet connections, or a desire to fit an entire library onto a retro handheld or a USB stick, compression is not just a luxury; it is a necessity.
But what does "highly compressed" actually mean? Does it ruin the game? Can your emulator run it? This article breaks down every method, tool, and risk involved in shrinking PS1 and PS2 games.
Before you download anything, you must understand the physical media.
The Golden Rule: You cannot compress a 4GB PS2 game into 100MB without destroying it. If you see a file that claims "GTA San Andreas 50MB Highly Compressed," it is almost certainly a virus, a fake, or a stripped-down beta.
Ask any football gamer over the age of 25 about their childhood, and they will likely tell you tales of the PlayStation 2 era. It was a time when football games were defined by gameplay mechanics rather than graphical fidelity or microtransactions. Specifically, it was the golden age of Pro Evolution Soccer (PES).
While modern consoles boast 4K graphics and hyper-realistic stadiums, there is a massive community of players still searching for PES PS2 highly compressed files. But why is a game from two decades ago still in such high demand? And what does "highly compressed" actually mean for you?
Let’s dive into the world of retro football gaming and find out how you can relive the magic without maxing out your hard drive.
If you want a specific section expanded (e.g., step-by-step backup and compression of a legally owned PS2 disc, emulator setup, or verifying archive integrity), tell me which and I’ll provide that.

The fan in Rizky’s PlayStation 2 was wheezing like a dying asthmatic, struggling to push the humid Jakarta air away from the overheating processor. It was a Tuesday night, the kind where the heat stuck to your skin, but Rizky didn't notice. He was busy staring at a loading screen that had been frozen at 12% for ten minutes. pes ps2 highly compressed
On the scratched disc lying on the carpet, written in permanent marker over a generic silver surface, were the words: PES 6 - ULTRA COMPRESSED - 10MB.
"Ten megabytes," Rizky whispered to himself, wiping sweat from his forehead. "A whole game in ten megabytes. It’s impossible."
He had bought the disc from a vendor in Glodok market, a guy with bad teeth and a conspiratorial whisper who promised that this wasn't just a game; it was a "developer leak." He said the compression was so tight it was practically a zip bomb of pure entertainment. Rizky, a student with more time than money, had handed over his five thousand Rupiah.
Chk-chk-chk.
The laser assembly inside the bulky black console whirred, stuttered, and screamed. The percentage counter on the screen jumped.
12%... 14%... 98%.
"Whoa," Rizky leaned forward.
The screen went black. Then, the familiar, triumphant trumpet blast of the Konami logo attempted to play, but it sounded wrong. It sounded like a trumpet being squeezed through a vacuum cleaner hose—garbled, static, and low-pitched.
The main menu appeared. It looked like Pro Evolution Soccer, but in a nightmare dimension. The font was jagged. The background image of a stadium was a pixelated smear of green and gray, looking less like a football pitch and more like a swamp from a 1980s horror movie.
Rizky navigated to Exhibition Match. He selected his team, but the names were wrong. Instead of "RONALDINHO," the text read "R_NULL_9." Instead of "HENRY," it read "ENTITY_A." The player models on the team selection screen were wireframes—gray, blocky silhouettes with no faces. The Ultimate Guide to PS1 & PS2 Highly
"Maybe it’s just a bad rip," Rizky muttered, trying to rationalize the unease crawling up his spine. "Just a glitchy ISO."
He started the match.
The stadium loaded. There was no crowd. The stands were empty, rendered in a depressing, flat gray texture. The grass wasn't green; it was a sickly shade of neon teal. The sky above was void black.
The referee blew the whistle. Or rather, the game played a sound file that sounded like a sharp intake of breath.
Rizky kicked off with "ENTITY_A." The animation was fluid—too fluid. The players didn't run; they glided across the neon teal grass, their legs moving in a frantic blur while their torsos remained perfectly still.
At first, it was funny. Rizky laughed as the goalkeeper flew out of his box and spun in a circle for no reason. He laughed when the ball clipped through the crossbar and got stuck in the sky.
Then, the compression artifacts began to shift.
It was the 30th minute. Rizky made a pass. The ball hit an invisible wall and bounced back. Suddenly, the texture on the center circle of the pitch flickered. For a split second, the neon grass was replaced by high-resolution, photo-realistic image of a dilapidated concrete room. A room with a single, bare lightbulb.
Rizky blinked. "What?"
He paused the game. The menu overlay was translucent, allowing him to see the "pitch" behind it. The flickering intensified. The gray, empty stands began to populate. "PES" typically means Pro Evolution Soccer, a football
Not with fans.
With low-poly models of the players, standing motionless, staring at the center circle. Hundreds of them. Duplicate upon duplicate of the faceless gray mannequins, all frozen in a T-pose.
A sound began to bleed from the TV speakers. It wasn't the crowd chant. It was a low, rhythmic thumping. Like a heartbeat.
Bump-bump. Bump-bump.
Rizky tried to exit the match. He pressed the Start button. Quit Game? The option highlighted. He pressed X.
Nothing happened. The heartbeat grew louder.
Suddenly, the ball on the field began to expand. It stretched and distorted, polygonal shards reaching out like tendrils. It wasn't a soccer ball anymore; it was a mass of glitching data, a writhing blob of corrupted geometry. It began to chase "ENTITY_A."
The player Rizky controlled started to
Many developers filled the outer edge of discs with garbage data (null bytes) to push game data to the faster-reading inner rings of the disc. Compressors strip this out. This is 100% lossless. Tools like UltraISO or CDMage allow this without touching gameplay.
Before FIFA became the juggernaut it is today (and before eFootball changed the landscape), PES was the king of the pitch. Titles like PES 6 and PES 2013 on the PS2 are often cited as the best football simulations ever made.
Here is why gamers are still hunting down these ISOs:
