VCS Game Maker: Build Atari 2600 Games Right in Your Browser
VCS Game Maker is a new browser-based, no-code engine for creating real Atari 2600 games. It uses Google’s Blockly to let you design game logic with visual blocks, then auto-generates Batari Basic, compiles it to a ROM, and runs it via the Javatari emulator. Free and open source under the MIT license, it’s still a work-in-progress but already a notable addition to the growing wave of modern tools for retro consoles.
Inside GASP’s Final UE5 Update: Ragdolls, Motion Matching, and ML Animation
Epic’s animation team dives deep into the last Unreal Engine 5 update of the Game Animation Sample Project, showing how they built lifelike active ragdolls, slope-aware locomotion, and slick multi-character takedowns. The stream walks through the Physics Control Component, new Chooser-integrated motion matching, Motion Warping-powered pairing, and constraint-driven IK cleanup. It also debuts the experimental Animgen ML plugin for training your own in-editor animation controllers. If you’re serious about third-person character feel, this is a goldmine of practical techniques.
🧰 Modern Tools & Debugging
Unity 6.5: New Tools for Faster Level Building and Debugging
Unity 6.5 packs a host of quality-of-life upgrades aimed squarely at faster level building and debugging. You get smarter grid controls for precise local and diagonal alignment, a revamped hierarchy window with customizable columns, and a powerful new Lighting Search to manage every light in your scene from one place. The updated Game view stats overlay now splits CPU/GPU times and memory, while the new Physics Debugger visualizes colliders and rigidbodies in real time.
Bug-Fix or New Feature? Smart QA Tactics Before Launch
When launch day is looming, every decision can make or break your game. This GIC 2025 session shows how to build a focused QA strategy under intense time pressure, prioritizing the bugs and features that actually matter. Discover practical risk-based testing methods, ways to slash scope safely, and essential pre-release checks you can’t skip. Perfect for teams who need to ship on time without shipping a disaster.

Why Your Unreal HUD Hitches: Inside Slate and Global Invalidation
Senior engineer Cody Albert unpacks why Unreal’s Slate UI can hitch under complex game HUDs, and how global invalidation changes the game. He demystifies invalidation types, the cost of child order vs layout vs paint changes, and how the Slate tick actually works under the hood. The session walks through enabling Slate Insights, interpreting traces, and using breakpoints and flashing widgets to catch bad invalidations. A Lyra bug hunt shows how a small layout change can repaint your whole UI—and how to stop it.
From Warp to DRAM: Reverse‑Engineering RTX 4090 Memory Latency
Starting from a trivial vadd kernel, this deep dive follows one LDG.E instruction as it navigates the RTX 4090’s memory hierarchy. Using pointer-chase benchmarks and Nsight Compute counters, the author reverse-engineers L1 and L2 set functions, the 36-slice L2 layout, and the mapping into GDDR6X channels, banks, rows, and columns. The piece quantifies real-world latencies (L1, L2, DRAM) and explains how massive warp-level concurrency hides them. It’s essential reading for developers optimizing CUDA or GPU compute workloads.
