    Aviator Predictor
    Aviator Predictor is a software project that claims to analyze crash-style casino games using historical results, cryptographic hashes, and AI-assisted calculations. It is designed for games such as Aviator and similar titles offered by online gambling platforms. The project describes SHA-256 and SHA-512 seed analysis as part of its approach to examining game outcomes. It advertises real-time crash predictions, although their accuracy has not been independently verified. Users can reportedly select supported platforms and inspect potential outcomes through a graphical interface. The repository also describes demonstration tools and templates for testing prediction workflows. It advertises desktop and mobile availability, including an Android APK. Importantly, cryptographic hash analysis cannot reliably predict future outcomes of properly implemented, independently generated crash games.

    HuMidi

    HuMidi

    Play MIDI like a human in ROBLOX with automatic sustain pedals.

    HuMidi is a universal piano auto player for ROBLOX. It plays even the most generic MIDI file with great depth, thanks to the humanization and automatic sustain pedal generation via Machine Learning models and algorithms. The pedals are generated with a thorough analysis of the MIDI data, adding more depth to your performance that no other MIDI players could! Personally have been tested in: - Visual Pianos - Starving Pianists - Digital Piano - Piano's Got Talent This tool is universal, as long as the piano in-game allows to be played on a keyboard.

One of its core strengths is the profile system, which lets users maintain separate mod configurations for different play styles or multiplayer compatibility.

    OSRS .json Hiscores

    OSRS .json Hiscores

    The Oldschool Runescape API wrapper that does more

    OSRS .json Hiscores is a server-side API wrapper designed to transform Old School RuneScape hiscores data into structured and developer-friendly JSON objects, addressing limitations in the official API’s output formats. The official API typically returns CSV or basic arrays, which can be difficult to work with, so this project restructures the data into meaningful objects that include player stats, rankings, and inferred metadata. It also adds additional logic to determine player game modes, including historical transitions such as de-ironing or hardcore status changes. The library includes functions for retrieving leaderboard pages, skill rankings, and activity statistics, making it suitable for building analytics dashboards or game-related applications. It supports TypeScript with full type definitions, improving developer experience and reliability when integrating into backend systems.
