UPDATE: Rapid progress! In less than a day, decompilation progress for (Saturn) Sonic 3D Blast jumped over 10% (from 80.30% to 90.54%). This seems to be moving faster for a number of reasons: - The newly-matched functions were already nearly finished, so getting these fully byte-exact took less effort - A few earlier fixes unblocked whole groups of functions - Register assignments were computed from the real (era) compiler's dumps, not searched for - Multiple Opus 5.5 agents worked in parallel, greatly speeding this up I wonder if this can hit 100% today?
UPDATE: Sonic 3D Blast (Saturn) is now over 80% decompiled - from 70.51% to 80.30% since the last update, with SONIC.BIN (the core 2D isometric game) now over 2/3rds decompiled. Once coverage reaches 100% for all four executables, there will still be work left to do: - Add support for all three releases of the game (NTSC-U, PAL, NTSC-J). Currently, this decomp project only supports the US / NTSC-U release. - Fully document the decompiled code, ensure it is as clean and human-readable as it can be while remaining fully 100% matching / byte-exact. When this is all done, my goal is to release a faithful native PC port that is built from this decompilation project. The source for both of these projects will eventually be released on GitHub.

We’re not here to tell people what to think. We, along with the likes of @TheDCJunkyard and @thesegaguru, will report on homebrew projects that we feel will interest our viewers and let them decide. It’s not our place to preach to anyone, nor should it be yours.
Is there any harm in using AI to work on — or entirely create — projects for the Sega Saturn and elsewhere in the retro gaming scene? Yes, PandaMonium says in this opinion column, equating such work to digital asbestos: segasaturnshiro.com/2026/09/…

What do you think about the new @AMD RX 10800XT based on microarchitecture RDNA 5 coming up? Insider leaks attribute gigantic specifications to the chip: up to 200 Compute Units (CU), a massive 512-bit bus, up to 48 GB of fast GDDR7 memory, and operating frequencies in the range of 3.1–3.4 GHz on the fresh 3 nm process technology. No mem bandwidth data yet.

A brand new 29B model that only activates 4B parameters AND fits on 1 x 24GB GPU? 🏆Beats Qwen3.6-35B on shared benchmarks. A China Telecom released Xing4.0-29B-A4B. Stats ... 🧠 29B total parameters ⚡ Only 4B active/token 💾 ~19 GiB IQ4_NL 📚 256K native context → 512K 🤖 Built for agents + coding + tool use 🚀 MLA + MoE + MTP + mHC 📜 Apache 2.0 And the official benchmarks are interesting: 💻 SWE-bench Verified: 75.0 🛠️ Terminal-Bench 2.1: 57.5 🤖 Claw-Eval: 76.55 A llama.cpp support PR appeared basically alongside the release with 👇 ✅ GGUF conversion ✅ IQ4_NL quantization ✅ CPU backend ✅ GPU backend ✅ MTP support The IQ4_NL build is just ~19 GiB. And the developer already published a Windows deployment recipe built around a single RTX 3090 24GB. The llama.cpp PR also reports: 🚀 ~151.7 tok/s generation ⚡ ~5,213 tok/s prompt processing ⚠️ The PR itself doesn't explicitly identify the hardware used for those benchmark numbers, so I'm NOT calling that 152 tps on a RTX-3090 yet. Yeah…I gotta try this one. 👀 🔗HF: XingChen-AGI/Xing4.0-29B-A4B
