Just added this egg toy upgrade patch. It'd be nice to have a full decompilation of the Mac version.

Updating the engine again, this time to SCI2.1. I'm using the debug interpreter from January 1995, which still supports 320x200 resolution graphics (SCI upscales them to 640x400). Quite a few code rewrites and a new set of system scripts were needed, but it compiles and works after that.

Now I won't be constrained by QFG1's original palettes. I'm now basing the day-to-night transition and palette mapping on QFG4, with the talker color assignment based on QFG1. This will require exporting the SCI1.1 pics and views (as well as the extracted AGS sprites) to BMP files, then importing them back into SCI2 resources to map them to the new palettes. The transition is surprisingly accurate.

To create the night and sunset palettes, it's just a matter of adding the pics' embedded palettes as palette resources, then applying a tint to said palettes (dark blue for night, orange for sunset).

QFG4 palette map
Global colors: 0-79
Palette 1000 is the global night palette. Palette 2000 is the global sunset palette.
UI colors: 80-111
Room colors: 112-235
Talker colors: 236-252
Remap color: 253
Skip color: 254
Only colors 0-79 and 112-235 should be tinted for the night or sunset palettes.

I've just finished my decompilation for King's Quest I! While WinAGI gives a warning about the absence of sound 34, this can be safely ignored.

The decompiled version is 2.0F, as that is the version being sold through digital storefronts. Now it's ready for testing.

Looks like you're making a lot of progress. Regarding the sound 34 issue, is that the only warning you got when you first imported it? I have KQ1 version 2.0F, and I get four invalid sound resource (34, 35, 36, 37) when I import it.

Also, the warning should say "WARNING: Sound34 has an invalid location (134703) in the VOL file(VOL.2)", which means there is an entry in the SNDDIR file, but it doesn't point to a valid resource in the VOL file. Is that the warning you got? Or did it say the resource was missing or absent? I just want to make sure WinAGI is working correctly and not giving the wrong warnings.

Yes, it gives this in the error log:
LOAD GAME WARNINGS:

  WARNING: Sound34 has an invalid location (134703) in the VOL file(VOL.2).

  WARNING: Sound37 has an invalid location (135787) in the VOL file(VOL.2).

Great! I've just completed the decompilations of the remaining demo packs. Just the KQ4 demo is left.

Oh no, a ton of coding has been done...
SQ1 about 85%, need more sounds, and more looks but can be played all the way through
SQ0 about 75%, can be played all the way through, but a bit buggy in places
SQ2 about 80%, can't be played all the way through, but only missing a few elements that make that possible
TLD 0%, that things just massive and haven't delved into it too far yet
SQ3 about 45%, most rooms are present but overall, very fragmented

By TLD, I assume you're referring to TLC, The Lost Chapter. Yeah, that game is massive. I've been going through the game's decompiled code and reconstructing it. One thing I did was merge Logics 249-254 (the alien shuttle cutscene) into a single Logic 249, freeing up some space for dynamic logics for underwater (and removing redundant code from each room as a result), as well as a RoomInit logic that properly implements local and dynamic variables and flags.

Any views that aren't animated have been made into add.to.pics to save valuable memory.

I've been moving any variables and flags that don't need to be kept on room change into the 220-239 range.

Also, I've removed the leftover items from SQ2 (save for the glowing gem, since only it returns in SQ3), which Wilco Interactive confirms are useless. That freed up some space for reorganizing the inventory and icons so that they can all be looked at via show.obj, which wasn't properly supported at first.

I've put up a decompilation archive for AGI games. I'm currently in the process of doing KQ1.

All right, things are nice and secure now! It's good to see you here again, Cloudee!

So the arcade is back. Too bad Flash is no longer supported on modern browsers.

I did have an idea about bringing things over to my new site, The Missing Floppies, but it looks like things are good here now. I'll still write things up there, and I even branched out to SCUMM games.

Good work updating to SMF 2.0.19. That will help ensure PHP 8 compatibility. Of course, SMF 2.1 was just released, but there's no rush to upgrade yet.

Yeah, I bet the mods installed made things a little harder. That's why I use XenForo, which was made by former vBulletin developers. It cost me $160, but with a lot of built-in features, I think it was worth it. The only third-party add-on I have installed is XenPorta ($40), which provides a portal for the forum. The only other add-on I have is the first-party XenForo Resource Manager ($65). I've uploaded my own template games with it.

Anyway, keep up the good work. You do your thing and I'll do mine.

Here's the SCUMM Tutorial. It's dated 1991, around the time of SCUMM v5 (i.e. Monkey Island 2)

And here's the SCUMM Manual. It's dated 1996, around the time of SCUMM v7 (i.e. Full Throttle, The Dig).
