LÖVE

Too bad about the broken "demo" program as it would be really useful for creating sounds and the code that creates it. I got it to work with löve 0.9, a pre löve 0.10 version of frames and a few simple edits, but it still crashes when I hit any of the "randomize" buttons.
It is useable, but it would be so much better to have a version that works properly without hassle.

Sorry if it's bad form to resurrect this thread. If so, let me know and I will start a new one.

I was excited to find this because I wanted similar functionality in a project I'm working on. So I spent some time over the past couple of nights getting it to work nicely with 11.3. After building the original (C/SDL) sfxr tool on Linux, I decided that it would be easier to fix this up than to generate builds of the original one for my collaborators to use. It was!
I used @linux-man's fork of LoveFrames with 11.x support and have posted a PR for @nucular's sfxr.lua repository here. I hope that will get merged in some form. If anyone wants to kick the tires in the meantime or would just find this as useful as I have, I've attached a .love archive to this post.

Nah, this i think is one of the legit cases where bumping old threads is fine, since it's on-topic AND you basically worked to do some compatibility edits on the old project to get it working again.
