Your RomM library, on your PSP. Browse, download, play.
Warning
Early development. Skiff browses and downloads your RomM library on a real PSP, but expect
rough edges, and copy PSP/SAVEDATA/ to your computer before you try save sync. Follow the
roadmap or watch releases.
Today, getting a game onto a PSP means downloading it on a computer, plugging in a USB cable, copying the file to the right folder and unplugging again. Skiff does it from the PSP itself: pick a game from your RomM library and it lands on the Memory Stick, ready to play.
Skiff is an independent project. It is not made by or affiliated with the RomM team or Sony.

Saves go to the same RomM slot where RomM clients such as Argosy keep PPSSPP's saves, and a real PSP and PPSSPP 1.20.4 load each other's saves (checked with one game). RomM's in-browser player uploads no PSP saves (a game's own save data) to RomM. See Sync saves.
- A PSP (any model) already running custom firmware. Skiff is tested on ARK-5 with firmware 6.61; installing custom firmware is up to you and not covered here.
- A Wi-Fi network the PSP can join. The PSP is old: it needs 2.4 GHz, 802.11b and WPA (not WPA2-only or WPA3). The Wi-Fi guide shows how to set up a safe one.
- A RomM server, version 5.3 or newer (5.4 or newer to sync saves and to get games sent from its web UI).
- Games you own. Skiff does not provide games.
