A collection of malware samples and relevant dissection information
This repo is a public collection of malware samples and related dissection/analysis information, maintained by InQuest. It gathers various kinds of malicious artifacts, executables, scripts, macros, obfuscated documents, etc., with metadata (e.g., VirusTotal reports), file carriers, and sample hashes. It’s intended for malware analysts/researchers to help study how malware works, how they are delivered, and how it evolves.

Emulator of NES, SNES, Sega Mega Drive, GameBoy video consoles
The nesbox/emulator is an open source, browser-based emulator for a collection of retro gaming systems (NES, Super Nintendo, Sega Mega Drive, GameBoy, etc.). It’s written in ActionScript/Flash, and the project includes SWF binaries so you can embed the emulator into web pages. The emulator allows users to load ROMs and play them in their browsers via the Flash plugin. It’s licensed under the MIT license, meaning it’s quite permissive in terms of reuse. While Flash is an aging technology, the project remains a practical way to access old console gaming via browser, as long as Flash is supported or available.
Flash + AIR sound effects generator. Based on Sfxr.
The bfxr project by increpare is a sound-effects generator tool originally built using Flash + AIR, based on the earlier Sfxr project. Its purpose is to enable users, especially game developers and sound designers, to quickly generate retro, 8-bit/“chiptune” style sound effects (“bleeps”, “booms”, “zaps”, etc.) without deep knowledge of audio signal processing. It offers an interactive GUI through which you can tweak many parameters (oscillators, envelopes, filters, etc.) to sculpt custom sound effects; you can preview in real time, export, and iterate. The project includes libraries, HTML templates, and both ActionScript and JavaScript code. It has been well-received (over a thousand stars), but as of 2025, it has been superseded by a newer version called bfxr2, which is a JavaScript reworking of the original.

From the creator of Super Hexagon, VVVVVV, the hit 2010 indie platformer, now available on android and iOS! Winner of Indiecade's 2010 award for Most Fun/Compelling Game. There are two versions of the VVVVVV source code available, the desktop version (based on the C++ port, and currently live on Steam), and the mobile version (based on a fork of the original flash source code, and currently live on iOS and Android). If you’re looking for the game’s text, that’s mainly (but not entirely) in the Scripts.cpp and TerminalScripts.cpp classes. These functions basically load data into a very simple script parser that controls cutscene logic. All the actual levels in the game are hardcoded in huge arrays generated with a map editor, which exports the levels in source code. Since the 2.0 update, the Windows, Mac and Linux versions of VVVVVV have featured a powerful and easy to use level editor.

Super Smash Flash 2 is the most must-play battle game with 28 classic
SSF2 Fan Club: https://www.facebook.com/SuperSmashFlash2FC/
Play SSF2 Online: https://www.freegames66.com/fighting/super-smash-flash-2/
Nice news for those who love Super Smash Flash game, the upgraded version is better and better with an extra 3 playable characters to swell the ranks too (Marth, Zero Suit Samus and Chibi-Robo).
Super Smash Flash 2's gameplay is very similar to the official Super Smash Bros. However, the most interesting feature of SSF2 is that character's health is measured by a damage percentage counter. It means a character is attacked, the damage will be accumulated, and percent value gets high.
The controls of Super Smash Flash 2 are also different from the previous version. Make use of WASD keys to move Player while the arrow keys are used to control second player. The O and P keys still remain in P-1's possession, the P key for standard attacks, the I key for shield, and the 1 key for taunting.

Fanvas is a tool which can turn flash into canvas animation
Fanvas is a tool by Tencent that allows users to convert SWF (Flash) animations into HTML5 canvas animations. It consists of two parts: a parser implemented in ActionScript that reads the SWF file and exports JSON. It also provides a JavaScript runtime library that interprets that JSON and renders the animations via the HTML5 canvas. It aims to support vector and bitmap content. It reduces the file size of the exported animations, and provides efficient playback through techniques like dirty‐region detection.
Juicy Breakout is a demo/example game created by grapefrukt (Martin Jonasson & Petri Purho) to explore and demonstrate “juiciness” in game feel, how small visual, animation, and feedback effects make a game feel more responsive, alive, and engaging. It’s built in ActionScript (Flash) and uses grapefrukt’s own libraries (grapelib) to handle game framework, input, rendering, etc. The demo showcases a Breakout-style (brick-breaking) game but with extra polish, effects, easing, cascading animations, sound, and visuals that exaggerate response so you feel every bounce, paddle movement, and collision. The source is under the zlib license, allowing free use and modification.
