[05:40] <grogbot> <antoniou79> @Puu can you specify which version of the Android port you were trying and what the issue was?
[05:42] <grogbot> <Puu> arm64
[05:43] <grogbot> <Puu> Ultima 6 says it isn't a game
[05:43] <grogbot> <Puu> and...
[05:43] <grogbot> <Puu> The game in 'Ultima IV' seems to be an unknown game variant. Please report the following data to the ScummVM team at https://bugs.scummvm.org/ along with the name of the game you tried to add and its version, language, etc.: Matched game IDs for the agi engine: winnie {"title.pic", 0, "c1749fc5bc2ff35470f649defcb03720", 1959},

[07:13] <grogbot> <ZvikaZ> Hi. I always wanted to see Willy Beamish supported in ScummVM. Saw that there were three attempts to support the Dynamix engine (DGDS), and all seem to be stalled. Is there something intrinsically difficult here, or is it just DGDS' bad luck?

[09:13] <grogbot> <anothersynthguy> Are there people who create NEW games with SCUMM language?
[09:19] <grogbot> <anothersynthguy> Is the SCUMM source for one of the popular LucasArts game available, I mean as a demo of how SCUMM source looks like?
[09:20] <grogbot> <anothersynthguy> Not necessarily a whole game, but let's say just the SCUMM code of one or two "rooms" of Sam&Max or Indy3... ?
[09:21] <grogbot> <anothersynthguy> Because I love these games, I'd like to see how they were coded to handle such a big number of situations / actions etc.

[09:54] <grogbot> <ZvikaZ> There's more to answer your question than that, but that we'd be a good first step.
[10:04] <grogbot> <anothersynthguy> @ZvikaZ thanks! Yes I read this article a few days, very inspiring!
[10:05] <grogbot> <ZvikaZ> Great!
[10:06] <grogbot> <anothersynthguy> @ZvikaZ do you think there is SCUMM script available for at least one room of Indy3, Loom, Sam&Max? Would be a wonderful example!
[10:06] <grogbot> <ZvikaZ> Take a look at Lucas' original Scumm tutorial:

[10:07] <grogbot> <ZvikaZ> And, there's something like 'dump-scripts' flag, don't remember it's exact name, see in the help. It will dump all scripts as you olau
[10:08] --> TAS_2012v joined #scummvm.
[10:09] <grogbot> <anothersynthguy> Wonderful this tutorial, I'll have a deeper look!
[10:09] <grogbot> <ZvikaZ> There are also tools to decompile the scripts, without playing, I don't remember now the details...
[10:09] <grogbot> <ZvikaZ> Enjoy!
[10:10] <grogbot> <anothersynthguy> About "dump-scripts" do you mean, while playing Sam&Max with ScummVM, i can enable a log window to display script?
[10:11] <grogbot> <ZvikaZ> > About "dump-scripts" do you mean, while playing Sam&Max with ScummVM, i can enable a log window to display script? @anothersynthguy Almost. You will play, and text files with the scripts will be created
[10:12] <grogbot> <rzil> It seems buildbot does not include fribidi in latest development build for windows... does someone know if this the relevant project https://github.com/lephilousophe/dockerized-bb ?

[11:05] <grogbot> <rootfather> @rzil the developer snapshots at https://www.scummvm.org/downloads/#daily already have FriBiDi support enabled π
[11:07] <grogbot> <rzil> Thanks, I have downloaded yesterday night from https://buildbot.scummvm.org/builds.html latest development build on win64 is it different build?
[11:07] <grogbot> <rootfather> yes, it's a different (largely unmaintained) toolchain
[11:09] <grogbot> <rzil> ok, thanks
[11:09] <grogbot> <ZvikaZ> Why do we still have the unsupported chain? Can't we just have the two links point to your updated chain?
[11:10] <grogbot> <rootfather> I haven't bothered moving my personal toolchain (that's where the developer snapshots and release builds are made with) to the buildbot since I shifted somewhat away from Win32.
[11:10] <grogbot> <rootfather> when I have some spare time I'll sync them

[11:29] <grogbot> <rzil> RE for dummies ep 1 (new WIP engine): What is the recommended way to type length prefixed (aka pascal) strings? char * make them appear as string literal (using ghidra) and the lack of null termination make it very confusingπ
[11:31] <Scummette> [scummvm] ccawley2011 opened pull request #2274: OPENGL: Use a 4 bytes per pixel mode when taking screenshots (master...gles1-screenshots) https://git.io/Jfa5F
[11:32] <grogbot> <mduggan> I finally completed a playthrough of Ultima 8.. the game can be finished just fine and the saves work great, so I marked it Testing instead of Unstable.
[11:33] <grogbot> <mduggan> @rzil there's a constructor for Common::String which takes len, String(const char *str, uint32 len) .. might be easiest to convert them to that on load?
[11:35] <grogbot> <mduggan> or do you mean during the RE process .. in that case, I'm not sure I have a good suggestion π
[11:40] <grogbot> <rzil> thanks, I do mean during RE process
[11:42] <grogbot> <Henke37> i am not sure if ghidra supports length prefixed strings
[11:42] <grogbot> <Henke37> you should file an issue asking for that
[11:43] <grogbot> <mduggan> looks like it's supported at some level, https://ghidra.re/ghidra_docs/api/ghidra/program/model/data/PascalString255DataType.html

[18:10] <grogbot> <ZvikaZ> Hi. Question for the RE veterans... When you start working on a new engine, how do you decipher the file formats? Do you RE the executable, and see how does it find its resources? I assume you have better methods, or at least some heuristics, or maybe some common tools that you try first?
[18:12] <dreammaster> That can be a complicated question. For me, I look for calls to file opens and then reads to locate places were data is loaded from disk. Then trace backwards to find out how the data is used, and maybe even start creating a structure based on what offsets in the loaded data are used
[18:13] <grogbot> <madmoose> @ZvikaZ Depends on the format. Hex editor first, look for identifiers, google around to see if it's known. For containers you can usually work out most of it just be inspection.
[18:13] <dreammaster> But generally, unless the data is easy to understand like a picture or sound, I'm not able to figure out what the data actually does until much later on in the process, when I've reversed more of the game, and understand what stuff is doing, before I worry about how it's first loaded
[18:17] <grogbot> <Henke37> i find that many formats have reoccuring features. chunks with 4CC lables and pointer tables are particularly common
[18:22] <grogbot> <madmoose> 80% of file formats are IFF.
[18:23] <dreammaster> Right. It's frequently possible to get an idea of the structure of such container files enough to identify individual elements, even if the meaning of the elements aren't always immediately clear
[18:24] <girafe> did you have help from original authors sometimes, or access to source code ? it seems a very difficult task to reverse a whole game engine and recreate it, one by one
[18:24] <dreammaster> Though sometimes you can get lucky. In some cases I've had methods reading data from a file have error checks for returned data that prints out error messages if it isn't valid. Which can be enough to identify the purpose of the data, which can also give some insights on it's purpose
[18:25] <dreammaster> Sometimes we do get access to original games source code. Some of the earliest games ScummVM supports, such as the Broken Sword series, gave from donated source.
[18:26] <dreammaster> But frequently it is indeed a laborious effort of disassembling the games little by little
[18:27] <dreammaster> Or a cross between the two. The recent support for sevreal Ultima games were based on separate projects that had already done the drudgery of reversing the games and reimplementing them
[18:37] <grogbot> <SupSuper> https://wiki.scummvm.org/index.php?title=HOWTO-Reverse_Engineering might help
[18:39] <grogbot> <SupSuper> i usually use a mix of observation and RE for file formats. there's some common patterns in files you learn to spot. if it's anything standard with a known FourCC or extension, that's 99% of the work done. archive formats usually have a table of contents with offsets and indices. images usually have sizes, palettes, pixels. RLE is pretty common. etc.

[20:49] <grogbot> <xesf> @ZvikaZ for DGDS there are various attempts. I started one recently for Johnny castaway but only got as far as setting up the scummvm engine: https://github.com/xesf/scummvm-engines/tree/dgds-castaway/engines/dgds Also did a viewer in JS so you can browse some of the game assets, but only few formats are working yet. https://github.com/xesf/dgds-viewer The more complete, but also older is Vasco Costa work:
[20:49] <grogbot> https://github.com/vcosta/scummvm/tree/master/engines/dgds He achieved quite a lot but things are all over the place, so a lot of clean up will be require if that will be a starting point. For Johnny Castaway, these are the most up to date: https://github.com/bailli/Johnny https://github.com/jno6809/jc_reborn (and my version in JS which is a bit outdated: https://github.com/xesf/castaway) Hope it helps.
