# PS2 Reference Notes
|
|
|
|
This folder is a planning-oriented reference bundle for the `retroDE_ps2`
|
|
core. It is not meant to be an exhaustive PS2 encyclopedia; it is meant to
|
|
collect the implementation details that are likely to matter when we turn this
|
|
into an FPGA project.
|
|
|
|
Files in this folder:
|
|
|
|
- `hardware_overview.md`: PS2 subsystem map, memory map, and boot flow notes.
|
|
- `software_and_emulators.md`: Open-source SDK, graphics libraries, and
|
|
emulator projects worth mining for behavior and test ideas.
|
|
- `implementation_workstreams.md`: A subsystem-by-subsystem map of what the
|
|
project would need to account for, plus an `ao486` comparison.
|
|
- `source_log.md`: Source list with URLs and short notes.
|
|
- `supplemental/`: Second-pass additions (Claude). Primary Sony manuals,
|
|
PSX-on-FPGA prior art as methodology templates, academic / community
|
|
feasibility material. See `supplemental/README.md`.
|
|
|
|
Suggested reading order:
|
|
|
|
1. `hardware_overview.md`
|
|
2. `implementation_workstreams.md`
|
|
3. `software_and_emulators.md`
|
|
|
|
Notes:
|
|
|
|
- These notes favor primary or near-primary technical sources where possible:
|
|
emulator source trees, SDK/toolchain repos, and low-level hardware
|
|
references.
|
|
- Some PS2 knowledge still lives in community documentation rather than
|
|
official Sony publications. Where that is the case, the source is called out
|
|
clearly.
|
|
- I did not find a credible open-source HDL PS2 core during this pass. The
|
|
public material that surfaced is overwhelmingly emulator, homebrew SDK, and
|
|
reverse-engineering documentation.
