Hey all! Yes, FLVER Editor 2.5 is still being worked on, and I promise it will be released soon. In the meantime, we're currently working on some new updates for a tool you may not have heard of before, but it's making some waves in the sound scene as ReWWise takes some time to get accustomed to implementing custom music tracks: the Custom Music Injector!
It basically works by hooking into the game's memory in real-time from an executable (will be a DLL file in the final version) and listening to events to determine when to play music, sound, dialogue, etc. from an internal player process. It's pretty nifty stuff, and you can check out the current version here: https://github.com/Pear0533/CMI
Let me know what you guys think! It is being worked on right now for the Convergence dev team, so it does currently have a couple of issues that are being ironed out. Other than that, enjoy!
