Thanks for the heads up! I've just restored the one from July which was working. You'd miss the improved final boss graphics and some minor stuff (but it works).
The new one was working here and seems to work from some people on Facebook. Thrown some FastRAM in your emulation config to make sure! It's always memory, this new version has that improved final boss leaving absolutely no leeway. Previously, we had some bytes left! And I'm talking chipRAM, which is the real bottleneck.
