What is a .PNACH file?
The most common data format on the web.
A .pnach file is a plain-text patch file for PCSX2, a PlayStation 2 emulator. It holds memory-patch instructions that modify a PS2 game at runtime, such as cheats, widescreen hacks, or 60 FPS patches. To use one, place it in PCSX2's cheats/ folder (the filename must match the game's CRC32 code), then enable cheats in PCSX2's System menu.

Frequently asked questions
Is my .PNACH file uploaded anywhere?
No. The file is opened directly from the copy you pick.
My .PNACH file is invalid. Can you fix it?
We show the exact line and column of the first error. For common problems like comments, trailing commas, single quotes or Python-style True/False/None, click Try to repair and download the fixed file.
How large can the file be?
Up to 50 MB. The tree only builds the branches you open, so even multi-megabyte files stay responsive.
What is JSONPath?
A path like $.orders[3].customer.email that points to one value inside the data. Click any node to see its path and copy it for code, jq or your API docs.
Can I see my data as a table?
Yes. Any array of objects can be shown in the Table view and downloaded as CSV.
