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

My old french bank testing in prod. Good job Cedric

Finished Saros tonight. Going to have to take a minute to process.

Philippe Vachey has restored and published the original soundtrack for 'Alone in the Dark', the French survival horror game that inspired an entire genre back in 1992. nowplaying.cool/after-34-yea...

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

There was a tremor in the force.

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

Yay

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

Loved Ghost Trick back then. Would love if they made another one of those.

@mdashow.bsky.social someone on Thursday was mentioning there was a bay area gamedev discord server and I needed to ping you?

A very french decor for a thai restaurant in Emeryville

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

Starwars trivia night. Did ok on the original trilogy and even prequel, but went downhill pretty quick on the sequel and tv shows questions. Still a lot of fun.

Starting to look interesting

It’s 2026 and I’m buying 5.25” floppy cleaning supplies 💾

Today I learnt there was an official Expedition 33 beret, and I'm almost tempted. #expedition33

This is not wrong.

I’ve made lots of progress made on my cozy building game: 🌳🏡Island Architect🏡🌳. Therefor time for a new gameplay collage for #screenshotsaturday! #indiegame #gamedev #indiegamedev

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

The Death by Scrolling console release and big Steam update have been announced!! 💀

BAY AREA: I will be setting up a table and selling stuff at this swap meet on April 18, down at Save N' Continue in Santa Clara. Really cool store if you haven't been, and the swap meet is always fun.

Don’t forget that today is the day to unlock Reala if you don’t have that on your Christmas NiGHTS save file!

Yeah, I’m definitely going to use that

Look at the pixel art! It's insane they got it looking this good on a Commodore 64, the same platform that Maniac Mansion was made on.

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.

@nfalstein.bsky.social trip down memory lane!

I've been focusing on town module lately, trying to get most locations in place. The seeker stronghold & caravan now load, but they are mostly empty without any NPC for now. github.com/yaz0r/Azel #decomp #panzerdragoonsaga

Trivia night!

Lego announced a Tintin Moon Rocket set. There goes my wallet... #tintin #lego www.lego.com/en-us/produc...

Always love to see lost media resurface

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

Gpu crash is always such a pain to debug. Hopefully that will help

This weekend, implemented the bulk of the baldor queen fight. As usual, bunch of hardcoded state machines, and for the first time, what looks like struct inheritance that I had to work around. Also implemented animated particle effects. #panzerdragoonsaga #decomp

@esper.bsky.social listening the even more games of the year 2025 while I'm working on something, and you sold me on Squeakross

Dusted off the ghidra database, made the first actual code commit to Panzer Dragoon Saga decomp in 5y

Revisiting a codebase I haven’t touched in 5 years…
