Looking at the posting rate right now, things have more or less quieted down and returned to
normal. So, the one and half of you who still decide to stick around must be interested in the
board and it's culture.
And I want to take this opportunity to indoctrinate you into creating OCs and flash hacking and
flash archival.
Currently, I'm working on doing an overall feature enhancement of Phoenotopia, but I'm afraid I
wouldn't be able to make it small enough to fit here. So this a filler post.
Other anons have probably already told you about the general board culture and I advise you to
lurk moar & to NOT turn out to be an obnoxious faggot like me, but I personally am taking this
opportunity to pass on the craft of flash making and hacking from a technical standpoint.
I won't be shitting up this board though, I will probably make a flash hacking general on /g/,
but I'll post things you should be familiar with if you want to become familiar with Flash
Hacking and Reverse Engineering.
Tools you will need:
>Something to make flashes with.
The popular options are Adobe Flash CS6 Pro, Macromedia Flash 8 and MX Professional 2004. I use
CS6 personally, so here's a torrent for that, which I sporadically seed when my computer is on.
https://files.catbox.moe/e9hpnv.torrent
>SWFTools
A suite of useful SWF utilities
http://www.swftools.org/download.html
>JPEXS' Free Flash Decompiler
A bit clunky at times but otherwise very useful tool. It's main utility lies in being able to
quickly sort through tags(which are the functional units of an swf) of different types while
providing a reasonable set of utilities and bringing them under the same roof. It has an
experimental Action Script Editor but that is generally unreliable and you should learn the Flash
P-Code.

>SWFpack
I was until recently blissfully unaware the LZMA compressed Swfs exist but you don't have to be.

The next most important thing is learning what a flash even is.
I will go into it in more detail in whatever general on /g/ I end up creating but the down and
low is that Flash is a really odd virtual computer by computer standards.
Flash works in essence as a Stack based virtual computer, much like languages like FORTH and some
other stack based computers, most of which are meme tech today for consumer applications. But
stack based computing in general is a pretty popular paradigm and it's very easy to design
conceptual computers around it with very minimal instruction sets.
Interaction with the stack in the program is done through One byte opcodes(Contrast that with the
fact that almost every practical architecture based around 16bit or higher fidelity data, has
multibyte opcodes, and even many popular 8bit architectures like the Zilog Z80 have them), called
the P-code. What sets flash apart is that while other stack based computers operate often on a
set of very primitive data types. Flash is a very complex machine and it's opcodes can handle
arbitrary classes most easily understood by thinking in terms of it's super language -
Actionscript. and it's in turn a very high level assembly compared to other computers.
The specifics of the architecture I won't go into right now, but in general it's a machine that
will be extremely impractical to implement entirely in hardware(still theoretically, possible
however) and you can put a large variety of data on the stack using the same set of opcodes.
I encourage you to read through this list provided by the JPEXS FFDec project:

To understand the workings of flash as a computer.
But almost equally as important is understanding the layout of the ShockWave Flash (SWF) as a
file format.
To facilitate that, you have to understand the basic structure of a swf.
SWFs are multimedia files that function as a container for various media types and support
various formats of data within themselves.
A first level understanding divides an SWF in two parts - It's header/Signature followed by the
Actual Movie (SWFs are called a "movie" format, so you'll be seeing the term often). The 8-byte(8
bit bytes to be precise) Signature firstly identifies that the Flash is indeed a flash -> byte 1
and byte 2 of any swf are always W,S in ASCII/UTF-8 or 0x57,0x53 in hex. The first byte describes
what compression algorithm has been used to compress the movie that follows the Signature.
C (0x43) -> DEFLATE, the popular backbone behind PNG and ZIP, has been used.
F (0x46) -> The Movie is Uncompressed
Z (0x5A) -> I am baffled how I remained unaware of this but I did pretty much fuck around and
found out so thanks that one anon for making me aware of it. This is an LZMA compressed SWF, but
/f/ does not allow uploading these. So if you have an LZMA compressed flash, use SWFpack to
decompress/recompress that to an uncompressed or DEFLATE compressed swf. Or you can just rip the
file from 0x8 onwards and work on that directly.
Next, The movie. In general the movie itself is composed of A global header, which contains a
RECT field, telling the projector/plugin, what should be the dimensions of the window (It's a
pretty involved bitfield thing for something so simple. The first 5 bits are the size of the four
bitfields that follow

Xmin, Xmax, Ymin and Ymax, or Xoffset, Width, Yoffset, Height as I like to call them, each
exactly as many bits long as the RECT's first field says, padded with 0s to round it up to a
byte. Since RECTs are used pretty often in all tags, this actually saves considerable space. What
doesn't make sense is that this bitfields are signed, lmao.)
Following this RECT in the header are a couple additional fields, for frame rate and frame count,
following which is a stream of position independent tags, which the players parses and loads into
neat little objects that the P-code references and executes.
A comprehensive list of these tags can be found here:
http://www.m2osw.com/swf_tags
and
https://open-flash.github.io/documentation/swf/tags/
I hope this material is enough to spark technical interest in the field, outside of the SOVL
flash generally provides. I hope to see you new/f/ags, and some of you old/f/ags, in the general
I will make on some other day.
Meanwhile, I'll finish up with my Phoenotopia project, upload it to swfchan and get back to you
so that you can play it with the minor enhancements I have made.

What is this crazy shit? Don't take it bad OP, but to welcome "newfags" with this esoteric
mumbo-jumbo won't do any good thing to make them to appreciate flash. Flash is an incredible
simple and powerful to create interactive media. The right approach should be to guide them to
create a simple swf. Basic Script for sSound, back and forth buttons, simple transition
animations, etc.
>> [_] Anonymous 04/02/25(Wed)10:57:36 No.3523489
>>3523487
Yeah and no worries mate. Ripping SVGs is pretty simple as far as flash goes, you just look for
the /DefineShape(2|3|4)?/ tags. FFDec has a nifty interface to isolate and export them with a few
clicks.
>>3523488
I know, that's why I said in general the tip for them is to Lurk Moar and not be a faggot like
me, but I am a computer enthusiast so it's just as much fun for it to understand flash as a
computer and as a file format. Besides, The flash scene is a pretty good allegory for a post
zombie apocalypse world and I think we can all benefit from indoctrinating some new/f/a/g/gots to
help us maintain the infrastructure. You can always just play the game and move on though.
I am not going to shit the board up with this shit though. I'll try to keep this going on /g/

That was a lot of technical info to dump but I don't think it'd be bad to have technical
discussions on flash stuff here every so often, I just make simple loops but I'm usually looking

how, going more into HOW TO FLASH would help even those of us that have been here a while get

This board was never meant to be organic, that's the problem. If /f/ could have threads like the
other boards, where you could build your own flash projects and anons could follow those
developments and engage in dedicated threads contributing with images and resources, then that
would be a revolution for /f/, flash could have a real renaissance. Of course that would mean a
fuck ton of file storage and moderation work. I guess we will never have that.

Do you mean saving the game to your pc/device, or saving the "game-play"? To save the game file
just click on the file link and it will be download it to your device as a swf file. You will
need a flash/swf player/projector to play it, you can find it easily as "flash-standalone" on the
webs.
About saving your game-play, If the game doesn't give you the options to save your game then you
have to start again.
You have the swfchan site with a huge archive of flash games.

it automatically or at the very least as a compression setting. If this is not the case and
instead has to be done externally, though the functionality is internal; then can it be done

It's possible to recompress any swf.
You just have to redo th 8byte signature with Z as byte 0, and then recompress the rest of the

Any utility to decompress lzma + minor modifications in the signature (byte 0 and the size field)
are all you need.
It's pretty simple to make one if you know how lzma and deflate work, infact. Swfpack is a

FFDec can not only open them all, but also save them in all three formats. You can change that in

convert flashes to LZMA though, saving some 10 or 100 KB is not worth the decreased compatibility.

4plebs has the archive for /f/, 4chan doesn't have one; when browsing you can view 100 pages back
from the searched date. swfchan.com scrapes all flashes posted to /f/ and swfchan.net and stores
it according to hash (I think), so multiple filenames of the same flash will link to the same one
