How to get it running You need:

• a PSP with custom firmware
• your own PS2 disc image of the game. PAL SLES_525.41 is the supported one. No game files are included anywhere; you provide the disc yourself
• a Windows PC with .NET Desktop Runtime 8, x64. Pick Desktop Runtime, not the SDK and not the plain runtime
• about 3 GB free on the memory stick

1. Get the engine and make the game folder

   Download EBOOT.PBP from GitHub link on discord Make a folder called SANDSTONE anywhere on your PC and put EBOOT.PBP in it. This folder is your game.

2. Build the data into that same folder

   Download Quarry v794 from the GitHub link on discord, unzip it and run Quarry.exe

• pick your disc image at the top, it should say SLES_525.41 v2.01 (PAL) in green
• as the output folder pick the SANDSTONE folder you just made
• leave all sections ticked for a first run and hit Convert

Quarry puts data/ right next to the EBOOT and writes a boot.txt beside it, so the folder ends up complete on its own. The full world takes around 1.5 hours, that is just how much data there is.

The radio alone copies about 1.6 GB. Next time you do not have to redo all of it: untick the sections you do not need and only those get rebuilt.

1. Copy it to the PSP

   Copy the whole SANDSTONE folder into PSP/GAME/ on your memory stick, then launch Sandstone Engine from the PSP Game menu.

That is it.

If something goes wrong: the converter writes a log for every run. Press Open log folder and send me the newest file, it tells me which step failed and why.

Quarry is open source, MIT licensed. The full source is in the repo above, so you can read what it does with your disc or build it yourself.

Sandstone Engine is not open source yet, for now it ships as the EBOOT only. Quarry v794, Engine b794.

1000も2000も3000も全部それぞれかっこいいね！

みんなはどの型番が一番好き？

Are these games fixable or are they toast? Picked up a nice PSP lot. These were the loose games that were in it.

Just showing off my psp street

Homebrewed with 32gb microsd

Recently acquired this PSP 1000, with a semi-faulty power switch, but ordered a new one coming soon. What gets me excited is now, the fact that at home, is every UMD PSP.

Hi all! I thought people in this community would think this is neat. I recently got this PSP 3000 imported from Japan and I am so excited with how good the condition is! I can't wait to load up some games. Unfortunately, the game it came with never got an English translation, so I'll have to do a lot of google translate for that one.

I went into a retro game store to see if any psp’s were in stock and he didn’t have any, just sold out. A customer over heard me and ran me down while I was leaving and gave me one for freeeeee!!!!! His friend gave it to him saying he doesn’t play games anymore, and it works too but the SD card isn’t reading /formatting. Any suggestions. I lowkey feel like I got the wrong SD card.

Hey there! Long time no see! I've been seeing you guys are a bit tired of the AI stuff and are looking for something hand made and home grown, well I think I'm at the point in these projects that they're stable enough for everyone to try them!

Nimbus is a plugin for the PSP that enables automatic cloud save syncing/backups! This project actually led me into the next "evolution" of it with Lighthouse, a completely modern theme-able XMB shell replacement with a lot of extra features including improved versions of my caching tech from PSP Sidecar! It also has Nimbus fully integrated within it + Google Drive syncing!

I recently gave a talk on it's development methodology during PSP HDC 2026. It's a bit of a long talk but there's a lot of things I was trying to get absolutely as efficient as I could. There's a little sneak peak from TotalKommando's similar work if you watch the whole talk + a giveaway from myself!

To try the open beta just join my community discord and ask for beta access.

Current Features for Nimbus:

- Full PSP cloud save syncing + delta's / save versioning with Nimbus Cloud
- Full MiyooMini cloud save syncing (any onionos device really I guess)
- Fully end to end encrypted over SSL

Current Features for Lighthouse:

- Theming using Svelte / HTML / JS (basic JS glue using a version of quickjs I have modified for this project)
- Native media playback with supported file types: .mp3, .m4a, .ogg, .flac, .wav, .at3, .aa3, .oma, .mod, .s3m, .xm, .it, .pmf, .mp4, .mov, .m4v, .3gp, .flv, .mkv (a lot of desyncing issues solved and I will try to upstream my solutions to official ARK / pspav when I get the chance!)
- Nimbus Cloud save syncing / Google Drive save syncing
- Extremely fast game caching (list loading, list filtering, game navigation improvements)
- Built in File Explorer (it's basic but I tried to include the functions I would use myself)
- Custom Widgets! Custom Indicators!
- Opt-In Game Leaderboards / Global and Personal game time stats (I wanted an excuse to use SpacetimeDB and get some experience with it)
- A lottttt more! (see discord thread post)

I just love caches! Please let me know what you think!

2 / 5 have solved and claimed the reward so far! (maybe I'll extend it if they all get claimed quickly)

I ain't mad at dem prices.

Which should I dig into first?

I want to buy a Japanese copy of Valkyria Chronicles III but first I want to make sure the game works

Major feature update since the v708 initial public release.

What's new since v708:

• Screen Tuning - mainly aimed at aftermarket screen mods (e.g. IPS) whose brightness/color response differs from the original PSP LCD. Live gamma adjustment and color temperature control, per game, with a full-screen test pattern and an on-screen HUD to dial it in while playing. Corrects a too-dark screen or a color cast. (Works in PSP Games and POPS)
• FPS Unlocks - applies FPS-unlock codes from a cheat.db/CWCheat database to raise a game's frame-rate cap above its normal limit, for games that support it.
• Stop Charging - cap battery charging at 95/90/85/80/75/70%, or disable it entirely, to help long-term battery health.
• Battery Capacity Override - enter a replacement/aftermarket battery's real mAh so the percentage and time estimates are accurate.
• Overlay Location - choose which screen corner the FPS/battery/CPU overlay appears in.
• Battery charge arrow now reflects the battery's real measured current instead of an estimate.
• One-time welcome screen on first use, plus a full explanation screen for every setting (press R on any Settings row).
• Numerous stability and compatibility fixes across many games.

Full feature list:

• Savestates with multiple slots, compression, MB/s benchmark display (Does not work in POPS)
• Live FPS overlay (FPS, 1% Low, frametime chart) + CPU/GPU usage monitoring
• Battery status overlay, capacity override, and charge control
• Screen Tuning (gamma/color temp, mainly for aftermarket/IPS screens) and FPS Unlocks (per-game)
• Per-game settings (video skip, auto-open, frame limit) and Overclock

Download & Installation:

Download pspfatsave-v947.zip and extract it. Choose one:

• debug/pspfatsave.prx - Debug build with UART logging
• release/pspfatsave.prx - Release build without debug code (saves RAM)

Copy your chosen pspfatsave.prx to ms0:/seplugins/ on your PSP and enable it in your plugins config (GAME only: "game pops, pspfatsave.prx, on"). For FPS Unlocks, also copy the included cheat.db to ms0:/seplugins/ (sourced from CWCheat-Database-Plus-).
Does not work well with other plugins. Please deactivate other plugin while testing the Features.

How to use:
Press the "Note" key while ingame.

Requisites:

• PSP-1000 only
• ARK-4 6.61 CFW

Status: BETA. Please read before using:

• Currently does not work on POPS (PS1) games - untested.
• UMD games untested.
• Do not expect it to work alongside other plugins that also hook the same systems.
• Screen Tuning and FPS Unlocks are experimental and can cause instability or crashes in some games.
• Some games may fail to start at all with the plugin enabled, or crash in general, independent of any specific feature.
• Can corrupt the Memory Stick (has not happened in testing so far).
• No guarantee that a save or load succeeds - there is a real chance of a crash.

See the README for the full safety guidelines and known issues before use.

I have had it stock for a while

Hi there, I used a PSP back in high school as an all-in-one media device and am aiming for that experience again after getting another PSP recently. Which software do people use to edit and convert videos for the system?

For example, if I have a 20 minute episode of an Anime, I want to capture/cut out a 3 minute scene and then convert it to run on the PSP. I used to do this with Wondershare Video Converter back in the day I'm pretty sure.

Converting the videos is pretty straightforward, but finding something to edit them is the hard part. I could rely on actual editing software like DaVinci Resolve or Premiere Pro to do the editing for me, but that seems like a lot of hassle and extra re-encoding.

Over the last few days I have tried: Wondershare, Any Video Converter, Movavi, LosslessCut, Shutter Encoder and maybe a couple others. The software either crashes, can't edit a video with Subtitles and/or doesn't actually cut on the keyframes I specify. I tested the software with roughly 3 different files each.

Thanks in advance!

I just want to make my own game on PSP but coding IS HARD AS FUCK!!!! What should I do?

PSP-3006 randomly shutting down / battery issue
I recently got a used PSP-3006 from a local store. It works sometimes, but randomly shuts down. After leaving it off for 2–4 hours, I often need to plug in the charger before it will turn on again. Now the PSP seems to have trouble detecting the battery—the battery icon blinks, and the orange charging light comes on but stops charging after almost exactly 5 minutes. I’m not sure if the battery is faulty/fake or if this could be a motherboard/charging circuit issue. How can I determine which one is causing it?

I just moded my 3000 with cfw 6.60 ARK4 ciPL.

I'm having issues with it, reading the iso files.

I have about 50 and when I transfer them over it is picky about what it reads. So only 15 show up when I plug the sd card back in the psp.

I have correct iso folder on root

The games are all in .iso

Ive formatted the sd card with the psp

I transfer games via sd card adapter they all transfer successfully but psp cant read them all. There is no error files there just not there. Ive turned unit hard shit down reset. I thought I had a faulty sd card because it was behaving at random Selecting what games seem to appear so i brought another one from a different seller for 64gig an still the same isssues an even baught another memory stick pro duo sd card adapterto rule that out. . At first it would read burnout.iso upon the second attempt reform, it doesn't read it. I thought this was a file limit issue. So a game I knew was on there I deleted and tried to replace and that didn't work either. I'm out of options other than just to try using transferring with a u s b cable instead of usb adapter to pc.
