    JKSV

    JKSV

    JK's Save Manager Switch Edition

    This started as a simple, straight port of my 3DS save manager I publicly released in 2016. Despite not originally wanting to take it too far, I continued working on it for fun when I can. Dump and restore account save data. Dump and restore device saves shared by all users (Games such as Animal Crossing). Dump and restore BCAT Data. Dump and restore cache Saves. Dump system save data. Dumping this data is always enabled, but writing back needs to be enabled from the options menu. Writing to this can be very dangerous. Processes can be terminated from the Extras menu allowing you to open even more of these and explore more. Create save data so the user no longer needs to boot games to import saves. Titles can be rescanned from the Extras menu. For example, if you insert a game card while JKSV is open, rescanning will load and add it to the save creation menu(s).

    Unleashed Recompiled

    Unleashed Recompiled

    An unofficial PC port of the Xbox 360 version of Sonic Unleashed

    Unleashed Recompiled is a reverse engineering and recompilation project aimed at reconstructing Sonic Unleashed for modern platforms by translating original console binaries into readable and rebuildable C++ code. Instead of emulating the game, the project focuses on decompilation and recompilation, allowing the game to run natively on modern hardware with improved performance and compatibility. It works by analyzing the original Xbox 360 or PlayStation 3 binaries and recreating equivalent source code that can be compiled using modern toolchains. This approach enables developers to modify, optimize, and extend the game in ways that are not possible through traditional emulation. The project is part of a broader effort within the Hedge-dev community to preserve and modernize Sonic titles through open-source tooling and reverse engineering techniques. It also lays the groundwork for future enhancements such as modding support, graphical improvements, and platform portability.

    DevilutionX

    DevilutionX

    Diablo build for modern operating systems

    DevilutionX is a port of Diablo and Hellfire that strives to make it simple to run the game while providing engine improvements, bugfixes, and some optional quality-of-life features. Check out the manual for what features are available and how best to take advantage of them. You'll need access to the data from the original game. If you don't have an original CD then you can buy Diablo from GoG. Alternatively you can use spawn.mpq from the shareware version, in place of DIABDAT.MPQ, to play the shareware portion of the game. We hope to provide a good starting point for mods, in addition to the full Devilution source code we also provide modding tools. If you want to help test the latest development stage of the next version (make sure to backup your files as these may contain bugs), you can fetch the test build artifact from one of the build server.

Currently, it will only work natively on Windows, although it has been tried through Wineskin on Mac OS X and currently works, though no guarantee is in place that this will continue to be. Maximising that support is a priority, however. Please note: unless otherwise stated, EE Keeper will be archived in Zip format and uploaded. Please note, any support ticket that is created should be watched in case any extra information is needed. If you do not plan to keep and eye on your ticket and you have an account on the official Baldur's Gate forum, please be sure to provide your user name with the ticket in case any further information is required.
