Can't increase ram? (192mb limit on browser) #36

I get an error when I try to run Windows XP on the browser when I increase the ram. Is there any way to make ram reach 1GB for example? Thanks in advance, this is an amazing project

The problem is that WebAssembly sets a hard minimum/maximum memory import size at compile time, which isn't what we want. I couldn't figure out how to configure Emscripten properly.

I've managed to get around it by patching the WebAssembly file at runtime. The rewrite I'm working on has support for it, but it's not ready for release yet. This is definitely an issue, especially since I'm adding x86-64 support -- a lot of the guests don't like small RAM sizes.
