Looks like an awesome addition to the GB emulation world! I know GB Studio can export a web player—I wonder if this implementation has some advantages.
One major disadvantage is that this one doesn't seem to have an OSS license :(
Looks like the author has fixed that; it’s now available under the Apache License 2.0.
I’ll definitely have a look and see if there’s any advantages. Currently using binjgb in GB Studio and been pretty happy with it https://github.com/binji/binjgb
