Hey everyone, today I'm releasing my PS-Vita emulator, Tsubomi!

JIT is required. No, I will not add non-JIT support.

You can download Tsubomi here: https://github.com/125hz/Tsubomi/releases/tag/0.47.0

It's been a few months since I posted my original post, I think most games that work on Vita3K should work now, but honestly I haven't worked on it for about 1.5 months (been busy working on Madeira, a PC emulator, which you should check out here)!

If you have any issues, please post the in "Issues" on GitHub, or put a Pull Request in. I'll get to it when I have time.

Setup Guide:

Prerequisites - Stikdebug and PS Vita setup files (Preinstall, Font, and Firmware file. You can acquire these online from Sony as well as through the official Vita-3k emulator)

1. Install IPA with your preferred method/service

2. Attach "universal.js" to Tsubomi in Stikdebug

3. Launch Tsubomi through Stikdebug, and follow onboarding setup (installing all the firmware files)

4. Add your game's work.bin/license file and .pkg file, and play!

I do not support piracy. You will not get any support for pirated games. Please own a copy of the game you are trying to emulate. It will take me a while to get to any issues, as I am focused on upcoming midterms and busy with work.

If you run into any issues with games (i.e. graphics look off, performance issues, etc) change some of the settings around! Try high accuracy, async pipeline compilation, resolution multiplier, etc!

There is no Tsubomi discord, or any social media account. I do not want to run a discord server, so please don't ask lol

Credits: Original Vita3K team and all of it's contributors. They did most of the work, I just did the work of porting it to iOS.

AI Disclosure: Claude Opus/Sonnet 5 were used during development for both coding + debugging. The app has been thoroughly tested with the following games to ensure it works: Persona 4 Golden, VA-11 Hall-A, Amagami Ebikore+, Gravity Rush

Before anyone asks: yes JIT is required.

Been working on this for a bit since I haven't seen any other emulators besides Vion. Vion is another PS Vita emulator which is on the app store, though I'm not sure how many games are supported on there (and physical controllers aren't supported yet AFAIK).

Persona 4 Golden and VA-11 HALL-A are both in-game currently, both get past the menus fine and I've tested the first few minutes of them (though I'm not sure how far they'll go before hitting problems. Performance has been stable so far otherwise). Amagami Ebikore+ is fully playable as far as I know

Controller support works (physical + virtual touch controls), as well as trophies (unlocks, icons, trophy browser). I also implemented save exporting/importing.

It's forked from Vita3k, so a majority of the work was done by them. If there's a game you want tested, let me know and I'll see if I can get around to it

Please don't ask for release ETA. This is something I've been working on in my free time whenever I have a chance. I'll release it when I feel like it's stable enough

Edit: Figured I should add my phone/iOS version: iPhone 17 Base, iOS 27b3. At the moment, only iOS 26+ is supported for the app. I don't have any other devices to test it on below iOS 26, and I can't be bothered testing for any version below that. I also have not tested on an iPad.
