Astro Bot on PC: Jetsku U59 int20 setup and the Sky Garden test
Play Astro Bot on PC with this step-by-step KytyPS5 setup guide: download the Windows build, extract your own game files, add the correct folder, check the settings, and launch into gameplay.
The key checkpoint: Add the extracted Astro Bot entry, not the separately scanned backport entry. The recorded test reaches 60 FPS in places but drops substantially in Sky Garden.
Before you start
- Recorded build: Jetsku U59 int20; game 1.019, PPSA21567.
- Extract the complete game and allow substantial free storage.
- Keep defaults and cache behavior in mind on first launch.

Walkthrough 01
Identify the tested Windows build
The setup here uses Jetsku's fork of Kyty PS5. It runs the console game through an emulator, rather than installing an official Windows version. You don't need to compile the source for this guide. There is a ready-made Windows build. For reference, this recording uses a Ryzen seven fifty-eight hundred X and an RTX forty-seventy Super. Those details matter when you compare your result with mine. Reaching sixty in one area doesn't mean every computer, or every level, will behave the same way.
Let's start with the build, because downloading something with the same emulator name is not always enough. Open the Jetsku Kyty PS5 repository linked in the resources section, then open Releases. The release used for this recording is U fifty-nine, int twenty. You may see older releases while scrolling, including builds specifically for testing AMD graphics problems. The one we use here is int twenty. Expand Assets and download the Windows x sixty-four ZIP. Choose the ready-made Windows package, rather than the source-code ZIP or the Linux archive.
Extract the complete emulator ZIP into its own folder. Keep the files together, including the libraries and the preset file. If you're updating an older installation, use a fresh folder for this test instead of mixing new files with an old preset.
Walkthrough 02
Extract the game and add its folder
That matters because this release includes changes to how the game and emulator coordinate graphics work. The developer also notes that the first launch can rebuild caches and stutter. We'll come back to that when we look at gameplay. Next, have your own extracted Astro Bot game dump ready. The version shown in this recording is one point zero nineteen, with the title ID P P S A two one five six seven. That's the version I tested here, rather than a promise that every other version behaves identically.
If your game is still inside a ZIP, RAR, or seven-Z archive, extract it first. The folder picker in the launcher needs the actual game folder. Pointing it at the compressed archive won't give it the files it needs to launch. Also check your free space before starting. A compressed archive can be much smaller than the extracted game. In this recording, the launcher later lists the game at roughly one hundred and forty-nine gigabytes.
Leave room for the extracted files as well as any archive you're keeping. Right-click the archive and use your extraction tool to unpack it into a folder you can find again. Wait for the extraction to finish completely. I'm shortening that wait in the video; there isn't another setting you need to change while it runs. Once it finishes, open the extracted emulator folder and launch kyty underscore launcher dot exe. Now we'll tell it where the game is.
This is the step to check carefully if you open the launcher and the list is empty.
Walkthrough 03
Recognize the correct launcher entry and baseline
Open the settings window using the sliders icon. On the General tab, find Game folders in the lower-left corner. Use the small folder button beneath that list to add your extracted game's location. In my recording, the game sits inside a folder named P P S A two one five six seven, with another folder inside it ending in dash app. Your drive letter and folder names may be different. What matters is selecting the location of the extracted game, rather than the archive you started with.
After you add the location, save the settings. If the list doesn't update immediately, use the refresh button in the launcher. The checkpoint you're looking for is an entry actually named Astro Bot, with its artwork and game version. In this recording, scanning the outer folder also picks up a separate entry called backport. That is not the Astro Bot entry we're going to launch. Select the row with the Astro Bot name and artwork.
Before starting, here's the settings baseline visible in this test. The screen-resolution field is twelve-eighty by seven-twenty, the present mode is Mailbox, the V blank frequency is sixty, and shader optimization is set to Performance. GPU selection is Auto. Treat those as the settings used in this recording, rather than a guaranteed best configuration for every PC. And the resolution field by itself doesn't prove what internal resolution the game renders at. The important thing is to start with a known setup and compare the same scene if you change something later.
Walkthrough 04
Allow first launch and inspect the opening
You also don't need to turn on every experimental option to follow this guide. Get the game launching with a clear baseline first. If something goes wrong, it is much easier to work out what changed when you haven't adjusted ten things at once. Now launch the Astro Bot entry. A console window opens alongside the game. That is part of this launch process; seeing text appear there doesn't, by itself, mean the game has failed.
On this first start, there is a splash screen, a black screen, and then the PlayStation and Team Asobi logos before the opening sequence. I'm shortening those loading sections, but keeping the transitions so you can recognize where your own setup has reached. If your first start pauses, give it time to progress. The release notes specifically mention cache rebuilding and first-launch stutter. That doesn't explain every possible freeze, but it means an initial pause isn't automatically a broken installation.
Once we reach the crash site, you can see Astro moving around and the counter reaching sixty. This is the first useful checkpoint: we've gone beyond a logo or a title screen and can actually control the game.
Walkthrough 05
Test Sky Garden beyond the easiest scene
Now let's move into Sky Garden. This is where the result becomes more useful than just showing the easiest scene. The level loads, we can move through it, fight enemies, rescue bots, and continue to its end. But performance changes as we go. Some recorded moments are in the fifties, some are lower, and one early section drops into the teens. So this test reaches sixty; it is not a locked-sixty result throughout Sky Garden.
If you're comparing this with a clip online that looks smoother, check the processor, graphics card, game version, emulator build, and the area being shown. A different scene or a different setup can make a big difference. A first visit can also involve cache work, though this recording alone doesn't prove the cause of each slowdown. That should help you decide whether the current experience is something you want to try, rather than relying only on the best-looking few seconds.
What about finishing the whole game? A player on Reddit reports completing Astro Bot using the Jetsku build, and describes sixty FPS for much of their playthrough. They also mention visual problems in water levels, cloud issues, and stutters when entering new areas. I've linked that report in the description so you can read the details yourself.
Walkthrough 06
Separate community completion reports from this test
That is encouraging, but it's their completion report. My recording here shows the setup, the opening, and a run through Sky Garden. I haven't tested every level in this video, and I don't want you to confuse somebody else's full-game result with what I've personally demonstrated. For me, the useful progress is that we can set this up, control Astro, play through a level, and return to the map. There are still performance and compatibility differences to work through, but this is already something you can evaluate through actual gameplay.
If you get stuck, start with the checkpoint you reached. An empty game list points you back to extraction and folder selection. A game that appears but won't launch is a different problem. Include the exact build, game version, your PC specifications, and what happens when you ask for help. Those details are much more useful than just saying it doesn't work. And if you'd like to keep testing builds with us, join my Discord through the link in the resources section.
I contribute to Kyty, and I'm building a community where we can compare results, help each other with setup, and share useful feedback from testing games we own.
If your result differs
| Situation | Next useful check |
|---|---|
| The game list is empty | Add the fully extracted game location and refresh the list. |
| A backport entry also appears | Launch the row named Astro Bot with its artwork and version. |
| Sky Garden runs slower | The recording includes substantial drops. A 60 FPS counter in one scene does not establish a locked rate across the level. |
