Found it on pixiv. It's AI, but that doesn't bother me. Maybe someone here will also like it. I don't speak japanese, but I'm guessing it's an alternative world where they aren't blood related. Perhaps someone could translate.

Hi everyone!

Today I'm excited to announce that the first release version of OreImouto Re:Port is finally out and available to download!

First of all, my apologies for the slight delay — the initial release was planned for October 1st, but I needed a couple of extra weeks to polish things up and make sure the first playable build is as solid as possible. Thank you all for your patience and the amazing support on the announcement post!

For those who missed the previous post: OreImouto Re:Port is an unofficial fan reimplementation that brings both Ore no Imouto ga Konna ni Kawaii Wake ga Nai PSP visual novels together into a unified, modern engine without requiring a PSP emulator.

Key Features:

• Native builds for Windows, Linux, and macOS (Android build will be available later)
• Keyboard, mouse, and gamepad support
• Modernized UI and texture upscaling
• Multilingual UI (with support for patched/translated PSP ISOs)

How it works:

The project is completely free and does not include any original game data. On first launch, you will need to provide your own copies of both PSP game disc images (ISOs). The engine verifies and repacks the necessary assets, so you won't need the disc images after the initial setup.

Since this is the first public release, there might still be some bugs or edge cases. Feel free to join our Discord server to report any issues, share feedback, ask questions, or just hang out!

Disclaimer: OreImouto Re:Port is an unofficial fan project and is not affiliated with, endorsed by, or sponsored by the original developers, publishers, or rights holders.

I'd be happy to hear your thoughts and answer any questions in the comments!

The first one was tracing a tcoaal meme and the second was 100%, i think the difference of quality already says that

I am just a casual oreimo fan. But I would love to share my love for this anime and contribute to the fandom.

I watched the whole anime twice, watched the ovas, the blu ray special vids, everything. I played the PSP game, both games, and I downloaded the emulator just for this, and I don't care what people say about other girls and morality and what not, Kirino best. No one will beat kirino. I absolutely adore Kirino. Kirino is the best and I will hear nothing else. NO one can beat Kirino. Other routes pale in comparison. The taboo makes everything hot and Kirino is the best. I am typing this while listening to my uni lecture but I don't care because Kirino is the best. when I think of the letter K I immediately think of her. Every time my professor mentions a word that starts with k, I think of my goddess. Kite? Kirino. Kitchen? Kirino Shut the fuck up Kirino is the best. I don't care about the contents of the lecture because Kirino is the best. Downvote me to oblivion I don't care because I have received the blessings from my goddess. I wish the Japanese fandom was still active. Im japanese but i couldn't find a local community to share my simple passion for this work so I appreciate this space. I thought about posting this on japanese subreddits but judging from the upvote/downvote ratio I got on my relatively tame post (also about oreimo) I decided against it. so thank you.
