In what way did it crash? What browser and device did you try running it on? - There might be an issue where its possible to start typing before the program load sequence has finished, e.g. where it has queued a "RUN" command for when the disk load has finished, but if you start typing before that, it might interfere with that RUN. I have an idea on how to fix that, if this is the issue. Just need to ignore key presses until all program load commands have been processed.
Do you mean specifically the Frogger game? Or in general? - If you mean in general, it hopefully does sound very close to the original VIC 20. I actually reversed engineered the VIC chip schematic from photos of the silicon chip, so the sound emulation is based on what I worked out from the reversed engineered schematic. Some of my discussion on that is covered here:
That's awesome! I had access to an electron microscope at my last makespace and always wanted to decap a simple chip for reverse engineering. A close friend of mine did that with a SID and recreated it in verilog with good results, which I always found fascinating. Great work on the VIC20 side! And yeah, my VIC20 was never the most stable machine, crashing frequently but I also had a bunch of janky expansion boards attached so ymmv...

Sounds authentic
