WASM version hangs on OpenSBI payload firmware

[repnop]

I've been developing an OS for RISC-V and use OpenSBI and was linked to this a while back and thought it would be an awesome way to have some friends be able to play around with it without needing to download QEMU or any of the other local simulators, however when I upload my OpenSBI payload bin, the page just kind of... sits there? Not really able to tell if its doing anything or not, but it seems like it just hangs :(

The CLI emulator successfully loads the payload and executes (for the most part, at least), so I don't think its the devicetree or anything like that. I'd love to have this available to me for sharing things, so if there's any way I can help debug this or instructions on how to better investigate things further, I'd be more than happy to :)
