+# 2,629 Tiny Demos from Pouet, Running in the Browser
+
+This website is a gallery of tiny demos scraped from demoscene aggregator [pouet.net](https://pouet.net), all MS-DOS .COM files smaller than 1024 bytes, emulated in the browser for your casual enjoyment. Some are [stunning](?which=88198), some more [basic](?which=52630), some [interactive](?which=61245). Some are [weird](?which=4661), some [don't work](?which=63118), and others straight up [crash the emulator]().
+
+But there are a lot of gems in there, and it's all there to click around and enjoy without the hassle of loading them into an emulator.
+
+## Why I Made This
+
+It wasn't my original idea to build this gallery. Originally, I just wanted to upgrade [Demo Baker](https://parkertomatoes.github.io/demobaker/build.html).
+
+Back in 2020, I had a dim flicker of brain cell activity: I saw "fits in a tweet" sites like [dwitter](https://www.dwitter.net/), the Windows 95 ["app"](https://github.com/felixrieseberg/windows95) was fresh in memory, and cool [boot sector](https://github.com/nanochess/Pillman) games were getting on HackerNews, and thought "how come no one's made an app-in-a-tweet site for x86?". Turns out [they did](https://github.com/AntoineViau/tweetx86), 
+but I didn't notice at the time.
+
+So I barrelled ahead and built a web-app that took an entire 512 bytes boot sector demo, encoded it as base64,
+and embedded it a URL:
+![Data flow diagram of demo baker](images/v86-demo.png)
+The site ran completely client-side from GitHub static pages, and allowed me to share links on forums to playable browser demos of interesting MBR and DOS demos I found, without needing any server-side storage. The whole x86 app fits in a [link](https://parkertomatoes.github.io/demobaker/?type=com&content=uBMAzRD8uACgjtiOwL7BAr8gFC6tkbvwANHhuBg3cwO4OALoIgAB34PrEHJP6BgAKd%2BD7wjr4q2XrYTkk7AwUMZE%2FwLorgBYUFNRV1C7eQIu15O5CACI%2BNDjcgIxwID%2FEHIHgD0OdJgyBari6YHHOAFYQKgHddVfWVtYw4HHiAmB%2FusCdY2xBbgCAC6lq%2BL7tADNGjsWBPp09okWBPq0Ac0WtAB0As0WiOA8AXUCzSAsSHIMPAlzCLv1Ai7Xov75viDmrZetkzHA6CsAgDb%2F%2BYC4KA54B6Ai5rED0uDoaP%2B9NwG3If%2FVty7%2F1bco%2F9W3NP%2FV65t0A%2BhO%2F4n4MdK5QAH38YjUCMSA5Ad1WrU3OG3%2FEOQ4rQAKEOQ4bQgQ5DitwP4Q5IT%2FdCv2wwV0DDsWAPqwAnIMsAjrCDwAsARyArABhMR1I4jYhMR1HdDodfiwCOv0iRYA%2Bi6iOgKg%2FvmExHUGINx0GojYiET%2BqAW7gP11A7sCAKgMdAL32wHfiXz8wwBC5%2Bf%2F%2F348PH788PD8fjz%2F%2F%2F%2F%2F%2F%2F%2F%2F%2Fzx%2B%2F%2F%2Fn50IAPH7%2F%2F%2F%2F%2Ffjw8ftvb%2F%2F%2F%2FpQAAABgYAAAAPH4%2FDw8%2FfjwAAP5%2FAkICQv9%2FQEJ%2BfgICfwLAA0ACfwJAAv5%2FAkL%2Fe0AKfn4CQP9%2FAACYqpBQmGSgPKhQAQAACAACAAAE&name=Pillman%20(by%20nanochess))!
+
+## Trying (And Failing) To Make It Even Easier
+
+This year I set out to upgrade Demo Baker to use the new, dynamic WASM version of V86, improve the presentation a bit, and allow things like titles.
+
+But I thought, 90% of the things I use this app for comes from [pouet.net](pouet.net). What if you could just drop in a URL from a product page and automatically run the demo?
+
+Even better, pouet has an [API](https://api.pouet.net/)!
+
+So I scripted up a test to run the demo, and... remembered why CORS exists:
+![Screenshot of a CORS error in Chrome](images/cors-error.png)
+
+pouet's API server doesn't support cross-origin browser requests, so API calls from my website to theirs won't work. And I'm too cheap and lazy to write a proxy - I want all this to be hosted statically from Github pages. So, plan A is out.
+
+
+## What if I just cached all the demos?
+
+1,000 tiny demos are still tiny. If I downloaded 10,000 1k demos from Pouet, the result would be about 10MB, which doesn't sound terrible. So, plan B: What if you provided the URL, and the app fetched the appropriate demo from a secret cache?
+
+The owners of pouet, wonderful people that they are, also provide a weekly [data dump](https://data.pouet.net) of their product index. That
+archive was 300MB though, too big to host in a GitHub page, so a little cleaning was needed. I wrote a NodeJS script to go through the giant JSON file and:
+
+ * Filter out demos that are larger than 1k and not DOS-based
+ * Strip out unneccessary metadata
+ * Follow the embedded link to download the demo
+ * Encode the demo in base64 and stuff in the JSON
+
+Pretty straightforward... except when it wasn't: 
+ * Many of the downloads are in .zip, .rar, .7z, .arj archives, etc.
+ * Some archives didn't have COM files or had COM files larger than 1k
+ * Many demos were linked to an _HTML_ page like this: 
+   ![scene.org screenshot](images/scene-org.png)
+ * Many links were broken/unsafe/etc
+
+But all that could be worked around. When filenames had an archive extension, I used a [NodeJS 7zip binding](https://github.com/onikienko/7zip-min) to search them for .COM files. scene.org has beautifully static and easy to scrape HTML, so if a URL contains "scene.org" the script follows the link. And it has _lots_ of corner case handlers for missing .COM files, bad links, etc.
+
+In the end, 2,629 demos were successfully fetched and stored in a JSON that was about 1.411 MB long, just enough to fit on a 3.5" floppy. 
+
+```json
+[
+    {
+        "name":"HaNsA KaOs",
+        "id":"698",
+        "content":"uBMAzRB...zRC0TM0hAAAA"
+    }, {
+        "name":"Bump Is Possible",
+        "id":"1380",
+        "content":"kLkAEIzIAu...sPSTs"},
+    }, 
+    /* ... +2,627 entries */
+]
+```
+
+## From A Cache To Gallery
+
+When you visit the [old version](https://parkertomatoes.github.io/v86/) of the demo baker page, it automatically started playing the boot sector pillman game by nanochess. Classic boot sector feat, but a little boring after 100 refreshes. So instead I rigged it to play a random demo from the index, and...

+
+_Psychodelic_. Refresh...
+
+This went on for an hour before I realized, this random demo should be the whole thing. I built a gallery with back, random forward buttons, the title of each demo, and a link back to the pouet page. An `<input>` with `<datalist>` served as a good enough search bar to look demos up by title.
+
+## One Last Task - Attribution
+
+At this point, I realized there really needs to be a link on each demo to the author's page. So, I wrote one last script to augment the demo list with the author using the original data dump. But it turns out the "author" field is pretty complicated:
+ * The demos can have one or more groups
+ * The demos can have one or more people in "credits"
+ * If nothing else, the demo has an uploader
+
+## Wrapping Up
+
+I'm unreasonably happy with this throwaway project - I'm Pygmalion over here. Staring at a random parade of tiny demos is incredibly hypnotic and beautiful. 
+
+Not all the demos work well, many have palette issues and some trigger illegal opcode errors. But this has actually help me find a few issues to improve v86. 
+
+Copyright is reserved by the creators. Legally, I consider this site an archive, like [demozoo](https://demozoo.org/), or [scene.org](https://scene.org/), or [youtube]() which already host all these demos. Its new purpose is to help you discover, appreciate, and learn more about forgotten, somewhat modest, but still extremely cool old demos.
+
+This is a one-off project for me and I don't intend to update the list  week to week. If a demo author finds their work here and doesn't want it here, please file a github issue and I'll promptly remove it.
+
+Now, please enjoy this [rotating 3d hat](https://parkertomatoes.github.io/demo-parade/?which=71639)

+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions. 
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version. 
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.
