    openbor

    openbor

    The ultimate 2D side scrolling engine. NOTE: Moved to GitHUB

    Please note: OpenBOR has moved to GitHUB. Latest source and binaries may be found here - https://github.com/DCurrent/openbor OpenBOR is the open source continuation of Beats of Rage, a Streets of Rage tribute game originally developed by Senile Team. In the years since it has grown into arguably the single most powerful two dimensional sprite based engine in the world and certainly the most versatile. While intended to allow creation of side scrolling beat em’ ups like Double Dragon or Final Fight, the engine is also capable of replicating Shumps, RPGs, platformers and the like. A built in scripting engine allows authors to take it even further, making imagination the only real limit. See www.chronocrash.com for more details and to download the latest versions.

    Dungeon Craft

    Updated emulator of Forgotten Realms: Unlimited Adventures

    Up to date code, including latest engine and editor releases: https://github.com/grannypron/uaf Dungeon Craft Community Forums: https://forums.goldbox.games/index.php#c8 Dungeon Craft is an adventure creator that emulates the Advanced Dungeons & Dragons Gold Box RPG's released by SSI. Initially designed to be a "more unlimited" version of the Forgotten Realms: Unlimited Adventures (FRUA) game editor and engine, it has far surpassed the capabilities of the old FRUA system. The editor is used to configure art, items, monsters, spells, special abilities, classes and races.. Each adventure is self-contained and doesn't require the editor to be played. The editor is extremely versatile and the databases are completely designer created allowing easy additions and modifications to spells, monsters, items, classes, races and special abilities, and are exportable to be easily shared with others or used in other designs.

    Retro

    Retro

    Retro Games in Gym

    RETRO (Retrieval-Enhanced Transformer) is a large language model architecture developed by OpenAI that augments transformer models with a retrieval mechanism. Instead of relying solely on learned parameters, RETRO retrieves relevant documents from a large external database during inference, allowing it to ground responses in external knowledge. This design improves factual accuracy, reduces hallucinations, and enables smaller models to perform comparably to much larger ones by leveraging retrieval. The repository provides code and resources for training and evaluating RETRO models, along with infrastructure for integrating retrieval into the transformer pipeline. It includes example configurations, datasets, and utilities for building retrieval-augmented generation systems. RETRO represents an important step toward combining large-scale language modeling with information retrieval, offering researchers a foundation to study hybrid approaches for scaling AI responsibly.
