should not pretend the interesting work only happened in the polished essays.
Why this file matters
Historical archive. This is older project documentation preserved for context. It is not the current source of truth, but it explains the roads that were tried.
This document outlines the plan to port Johnny Reborn to the PlayStation 1 using PSn00bSDK. The 4mb2025 branch has achieved 350KB memory usage, which is well under the PS1’s constraints (2MB system RAM, 1MB VRAM).
