Eisfrei

Introduction

Herzog Zwei was something of a cult hit back in the day. Although not a commercial smash, it had a base of fans who spent countless hours battling for supremacy. I've seen it called the first real-time strategy (RTS) game a few times but never bothered to check the validity of that statement. It doesn't really matter, it was an incredibly fun game that has been overlooked by all the Genesis collections and online retro-gaming services.

Eisfrei is a ROM editor for Herzog Zwei. It has a mostly-friendly interface that makes editing incredibly easy. No messing with hex editors, decoding values, or any of that. If you can click and type then you can hack away to your heart's contentment.

This first release of Eisfrei allows editing of text, unit attributes, order attributes, and tile-based graphics.

Please consider this project to be archived. I haven't made any meaningful changes since 2012 (or maybe earlier). It's built on a now obsolete version of .NET and I'm not planning to upgrade it. The source code will remain online and under a permissive license.
