PS1 CACHE memory fuzzer & simulator
docs/ps1/mem-fuzz-sim.md
This is the website shelf page for docs/ps1/mem-fuzz-sim.md.
It exists because the project has hundreds of Markdown files and the website
should not pretend the interesting work only happened in the polished essays.
Why this file matters
Active PS1 reference. This is active engineering documentation for the PS1 port. It is close enough to the code that stale claims here become real bugs.
A host-side tool that links the real PS1 CACHE allocator (src/memregion.c) and drives it with the PS1’s actual memory model so we can reproduce and prove out memory-exhaustion BSODs in seconds instead of multi-hour on-hardware/emulator soaks.
