I've been looking for a tool that lets me easily create GB Studio sound effects. FX Hammer is kind of a bear to use. Any chance of having a downloadable version to run outside of the web browser?
I hope it is useful!
You should be able to download and install it as a PWA app from the Netlify link in the description and use it offline. I'll be pushing updates through that link as well so you'll get them automatically.
Let me know if you have any feedback after you have a chance to try it out a bit.
