Back in February I headed up to Marin to backup some of Aric's old CDs from LucasArts era. In one of the backup, this odd demo surfaced. It's now preserved online.

In a very Indy-like move, we've unearthed a never-before-seen Lucasfilm Games Indiana Jones adventure! Note that we said "adventure," not "game." For possibly the first time ever, here's Indiana Jones and the Quest for Paradise VGA, the best ten-minute commercial you'll see this week.

Wrote a test harness that let me run the decompiled game in lockstep with the Ymir emulator, validating that for the same input, the game behavior remain faithful to the original code. This checks character position, camera, collisions, and can easily add more. #panzerdragoonsaga #reverseengineering

Tonight I'm trying to debug collisions. Very little progress, but I did add some better way to display the collisions meshes as that are tested by the engine. Large cities are sectorized in cells, so only a fraction of the collisions are processed around Edge. #panzerdragoonsaga #reverseengineering

Finishing up Dragon morphing tonight. Always wondered how that worked, and it's pretty simple geometry morphing. All dragons form share the same vertex count and topology. The textures are just interpolated on the CPU and updated in VDP1 memory per frame. #panzerdragoonsaga #reverseengineering

Played through the Adventures of Elliot demo. First, it’s a pretty long demo. And second, what a chatty companion! Even with reducing the talkativeness in the options, it’s pretty intense.

From the shelve, here is the pamphlet that was given out to press during the launch party of Heavy Rain in Paris. Should probably scan it at some point. (Amusingly it’s missprinted and has the same page twice in the middle) #heavyrain #gamehistory

I randomly bumped on the fact that Delphine Software "Cruise for a Corpse" was originally using very different graphics. That version is probably lost, but it's interesting to see what it was looking like before scraping all the graphics. #retrogaming #adventuregames

Here are some reviews for Puzzle Spy International. The Launch Sale is still going on for 2 more days so grab it for 15% off while you can! #puzzleGame #thinkyGame #indieGame #indieGames #sale #launchSale
A poster showing Agent Epsilon cheering, some environments from the game, and a yellow background. The text reads: "Reviews for Puzzle Spy International:

Puzzle Spy International deserves to be played by way more people...  You travel around the world, chatting with an excellent mix of characters... with the option of some flirting, and then solving a tricksy puzzle. And boy, they’re really good puzzles! 
- John Walker, Kotaku

Right away, I was drawn into the story. I like Agent Epsilon, as she's sassy and intelligent (a perfect female main character, I think.)
- The Introverted Gamer

It's a perfect short-but-sweet puzzle game with an amazing hint system that ensures you never get frustrated! Everything about this game is delightful. The artwork is super cute, the writing is incredibly charming... the music is great, and of course the puzzles! If you're a fan of Puzzled Pint, The Game, the MIT Mystery Hunt, Shinteki, etc. you'll absolutely looooove this game.
- Smijin

Part of the puzzle is figuring out how to solve it... This is the type of game that you sit with for a while before you reach that satisfying "aha!" moment (or better yet, solve the puzzles together with some friends!) You can tell these puzzles are crafted with care. Along each step of the way, it would blow my mind how the pieces would come together to reveal not just one, but so many layers of puzzles. 
- AHedgeHug

The puzzles have the right amount of difficulty and a new mechanic added to the mix: Hints that don't punish you. It's also not the same puzzle over and over: Each puzzle is a new experience, keeping you engaged and looking for what the next puzzle will bring.
- notyourboddhisatva

Scratches an itch which needs to be scratched again. The game is short, yes, but the puzzles are genius. Give me more of this please!

Been wiring a few more scenes in Saga decompilation. There is so much hardcoded logic in something like this. Still, I'm often impressed at the tricks they used to make this work on a Saturn. The vdp2 water distortion here works pretty well. #decomp #PanzerDragoonSaga #SegaSaturn

Let there be light. Background color is broken, but at least light is correct now. This is a more precise model compared to the original game (per vertex instead of per face, and interpolated depth instead of just 32 possible intensities). Can toggle the old Saturn computation at runtime.

Quite a bit of work on VDP2 lately, implemented the perspective planes, sky, and the weird fish eye effect. I always wondered how that worked. Turns out it's a per-pixel offset table covering the top half of the screen. Bottom is just reading the table in reverse. #panzerdragoonsaga #decompilation
