Arcade racing at its finest. Police chases, Blacklist rivals, and car customization are fully playable. Background music is slightly reduced in quality.
7. LocoRoco 2 (~45MB) The king of small file sizes. LocoRoco uses 2D vector graphics and catchy gibberish vocals. The game never exceeds 100MB in its original form, but highly compressed versions bring it down to just 45MB. You get the full 10-hour adventure. --- Psp Games Highly Compressed Under 100mb
8. Patapon 3 (~96MB) A rhythm-based RPG where you command an army of eyeball creatures by drumming. The file size is kept low by using repetitive audio loops and 2D sprites. Essential for any PSP emulator library. Arcade racing at its finest
9. Daxter (~99MB) This is the "Miracle Compress" title. The original Daxter (Jak & Daxter spin-off) is a full 3D platformer with voice acting and cutscenes. A standard CSO is ~400MB. However, scene release groups have managed to repack it to 99MB by downsampling the pre-rendered cutscenes (they look slightly blocky but still watchable) while leaving the gameplay untouched. The game never exceeds 100MB in its original
Explosive arcade racing. The compressed version removes the licensed soundtrack but keeps the crushing crashes, road rages, and takedowns.
Rhythm-based strategy cult classic. Since the game uses simple 2D art, compression barely affects visuals or audio. A must-have.
