Calling all Dreamcast developers! Today I am publicly introducing a SH4ZAM-powered self-shadowing soft shadows library to Sega@Dreamcast development. No more blobs, tearing volumes, or staying in the past. Dreamcast now has self-casting, feathered shadows in the big TWO-SIX! Highly recommend that you use it in conjunction with @falco_girgis SH4ZAM library for ultimate GAINZ! I had this shadow system developed for Halo: Dreamcast Evolved and wanted all Dreamcast developers to be able to use this performant shadowing system. Halo: DCE itself allows up to 6 characters on-screen at once to self-shadow with around 3-4ms only for draw time on around 5-6k vertices (YMMV). You can adjust it to your liking, of course. For Halo: DCE, I do the nearest 6 characters on-screen within about 9 metres from the camera before dropping and using only the cones ("fairy feet" as I call them...inspired by OoT). Shout out to @cypress577422 for assisting in squeaking out some more performance. What a helpful dev community! You can clone the repo here and get started immediately: github.com/JiltedValkyrie/SH… Ask your coding agent to help retarget your meshes to the bones to get it up-and-running quickly (or do it yourself if you care). Happy coding!

Years of hard work and experience by one fan have culminated in decompilations of Shenmue 1 and 2 for Dreamcast, Xbox and PC that were made public today. Read LemonHaze's story, which you'll only find on SHIRO!: segasaturnshiro.com/2026/10/…

UPDATE: I can confirm that the Ledger supply chain is compromised in Europe as well. @Ledger should initiate an immediate product recall to protect users. I just purchased a second device from a different Mediamarkt location today, recorded the unboxing process, and discovered spyware once again (video linked in the second tweet). The device was compromised in the exact same manner, featuring identical modifications (such as additional cables and an LTE module). This indicates its a widespread issue rather than an isolated incident, potentially affecting Ledger inventory across MediaMarkt and Saturn stores throughout Europe (comprising over 1,000 stores across 11 countries). My initial hypothesis was that these devices were returns that looked unopened to the employees and were just sold again as new however, a MediaMarkt employee confirmed that the device I purchased was not a return, and that returned Ledgers are sent directly back to the manufacturer rather than resold. Store records show the inventory originated from Aqipa GmbH. While Ledger's CTO was unsure if Aqipa serves as the direct distributor between Ledger and MediaMarkt, it appears to be the case. Given that Aqipa distributes across Europe, any physical retail store receiving stock through them may be at risk. I sent the first ledger to mark and the second one is going to ledger now, so that they can analyse it. If you purchased a ledger from anyone other than the official ledger store, make sure to check your device!!

I wrote a post explaining exactly why the Dreamcast will prompt you for the date/time even with a healthy battery, which has puzzled many of us for years! It's not your battery: the Dreamcast's hidden 30-day clock check dreamcast-talk.com/forum/vie…

Well, after 30ish years of not knowing the parity algorithm used by HOLLY to verify the Dreamcast BIOS, with the help of tools not available at the time (*cough* AI *cough*), I threw a bunch of #Dreamcast and #NAOMI SH4 Bootroms at it to check for Parity patterns and it found a match! No more testing for collisions on real hardware! (keep in mind that I haven't personally tested this yet, but there's no reason why it shouldn't work) github.com/mathieulh/Dreamca…

Resident Evil 1 continue sa décompilation PC… et là ça devient VRAIMENT intéressant 👀 Le projet est désormais quasi entièrement réimplémenté et le jeu est jouable de bout en bout 🤘 Windows natif en Direct3D 11 🤘 Linux natif via SDL2/OpenGL 🤘 Support de la version PC US / Biohazard JP 🤘 Contenu Director’s Cut PS1 via overlay 🤘 Aucun fichier du jeu distribué : il faut fournir ses propres données Au début j’étais assez mitigé face aux versions officielles modernes Mais là, entre le code ouvert, Linux natif et les ajouts autour du Director’s Cut… le projet commence clairement à avoir sa propre raison d’exister github.com/ecruells/resident…

🔥 Resident Evil: Code Veronica X vient de franchir une énorme étape La version PS2 est désormais entièrement décompilée : le programme peut être reconstruit depuis le code source obtenu par rétro-ingénierie Ça ne veut PAS encore dire qu’un port PC natif est disponible Mais une décompilation complète, c’est la base idéale pour aller vers : 🤘 ports natifs 🤘 widescreen / hautes résolutions 🤘 framerate débloqué 🤘 mods 🤘 améliorations diverses Bref, le vrai boulot de fond est maintenant terminé Projet : github.com/AshfordFamily/rec…
