Not 100% yet, but Metal is getting there! Still need to work out some push constant and barrier nonsense.
This week, I made a bunch of progress on XNOEdit, my cross-platform editor/viewer for Sonic '06 objects powered by .NET and WGPU.

Still lots to do, but many objects now correctly visualise, including textures! Next up, bringing in original recompiled shaders so everything looks perfect.

Been a bit since I've done a weekly update, so here's what we're up to! Lots of stuff is in the works:

- Achievement support (Hyper)
- Physics-based high FPS fixes and APIs for character controllers (Rei)
- MSAA & resize support (Rei & I)
- External cross-platform XNO editor (Me)

Stay tuned!

THAR SHE BLOWS 🐋 🫧
Huge scoop from Ed, who had several years of financial reports leaked to him. OpenAI has been over-reporting their revenue. The company is even less profitable than we knew.
Exclusive: Based on documents viewed by this newsletter, OpenAI spent over $12.4 billion on inference from 2024 to September 2025. As part of its Microsoft revenue share, it sent $493.8m in 2024/$865.8m Jan-Sep 2025, implying lower revenues than previously reported.

Yeah this pretty much sums up the Democratic party lol
The Reddit community r/Democrats has a conspicuous absence of any news about Zohran Mamdani today. But that's by design.

The moderators have rules that ban people from talking about democratic socialists.

After almost a month of work, the '06 recomp options menu has been merged!

This comes with a few new options, along with some improved existing ones to make them work at runtime.

It's still not 100% there yet though, as many of the video settings available are yet to be implemented on demand.

First run of Unleashed Recompiled on Mesa's new KosmicKrisp driver! Definitely room for optimisation, but this is seriously impressive.

To defeat the "vibe-coded gradient" allegations, I've redesigned my website! The palette is inspired by R. Kikuo Johnson's graphic novel "No One Else"

I'm sure there are bugs so lmk if something breaks :)

This week we got the infinite lives patch in!

Hyper is still hard at work on the options UI, so stay tuned for when that makes it in.
This week we got more progress from @hyperbx.bsky.social on the options menu! All of this is implemented outside the game's UI engine in ImGui :)

I'm sorry, we're doing what now?

For those interested in a deeper dive into Sonic 06's visuals, I've written a blog post on the main techniques used (and their many limitations).

Time to take a break from the race track for an update :)

This week, we got two restorations, chain jumps flips, and Sonic's action gauge!

If infinite hops aren't your thing and you want something more like Sonic Team intended, Sonic's gems will now (optionally) consume the action gauge.

Recomp delayed due to CrossWorlds, real

(In all seriousness, progress might be a bit slower this week lol)
