Hard to see the light now; just don't let it go. Things will come out right now. We can make it so.
Three young hopefuls arrive at the Guildleague, a land of promise for adventurers seeking riches, glory, and the chance to change the world. Unprepared as they are to, they will change the world, and the world in turn will change around them.
It is the beginning of the end. How shall they face it?
Hello, FEU! It’s Retina again. I’m proud to introduce a project I’ve been working on for around a year and a half now, Fourthhack (working title). More than my other two projects, I believe this is my unbridled creative vision, and I truly hope you enjoy what I’ve created.
DISCLAIMER: More than any of my other projects were at time of posting, this is a work-in-progress. Many graphical assets especially are either not in yet, or subject to change. There is also a great deal of custom code that may behave in unexpected ways. If you see anything that seems incorrect mechanically, please let me know!
NOTICE: It is extremely strongly recommended that you play on Normal mode for a first run. Some tutorials will not play on Expert and Heroic, and those difficulties are in general designed for those who know how to take full advantage of the game’s unique systems. Also, this hack has been primarily tested on mGBA.
UPS Patch (Apply to a US FE8 rom to start playing! Updated: 8/18/2026): Fourthhack.ups!

Special thanks to everyone in Retina Does a Thing for their support and encouragement, and to @ditto for helping me with way too much C code.
Sometimes people leave you, halfway through the wood. Do not let it grieve you; no one leaves for good.
