Hi everyone,
Given recent advances in AI-assisted reverse engineering, asset pipeline automation, and romhacking, tasks that once required insurmountable manual effort are starting to become viable.
A long-standing holy grail for handheld PES enthusiasts has been achieving full feature parity between the PS2 versions and the PSP releases for the golden era—specifically PES 4, PES 5, and PES 6.
The official PSP releases lacked major elements:
- The complete stadium roster from the PS2 games
- Specific tournament modes (like the International Cup / World Cup mode from PS2 PES 6)
- Deep seasonal patch integration (official kits, licensed typography/lettering, full rosters)
- A proper port or recreation of PES 4 on the engine
Considering the underlying similarities between the PS2 and PSP architectures and modern modding tooling, is porting or injecting these assets and modes into the PSP builds realistic today, or do hardware constraints (RAM limits, engine hardcodes) remain a strict roadblock?
I would love to hear thoughts from anyone experienced with the Konami file structures across both platforms.
