[Idea/Help Wanted] PS2-native Game Engine — building games ON the PS2 itself (like an on-console Godot)

[PS2HomeDeveloper]

Hey everyone,
I'm working on something a bit different from the usual PS2 homebrew project: a game engine that runs entirely on the PS2 hardware, letting users create, script, and export their own games/apps directly on the console — no PC required for the actual project-building step.
The idea in short:
Boots as a homebrew app with a project creation UI (choose 2D or 3D)
Built-in resource/asset browser tied to a real filesystem path structure (USB)
A built-in scripting language + text editor, since a full native C compiler running on-console isn't realistic on PS2's memory/CPU — so scripts get parsed into bytecode and interpreted by the engine at runtime, similar to how Godot's GDScript works
Export system that packages your project (ELF + resource folder) for USB, with ISO packaging planned as a later phase
Projects portable between PS2 units running the engine
This is a large project and I'd love help from anyone experienced with:
ps2dev / PS2SDK / GSKit
Embeddable scripting language VMs (Lua, Squirrel, AngelScript, or writing a custom bytecode interpreter)
PS2 filesystem/USB I/O
UI/UX design for constrained hardware
If this sounds interesting to you, or you just want to throw ideas around, I'd really appreciate the help. Happy to share more details on architecture if there's interest.
Thanks for reading!
