Putting vmWare on CHromebook would require a lot of efforts, and on base Chrome's most probably it wont help...
- install Ubuntu on Chromebook
- install wmWare / VirtualBox inside Ubuntu
- install Windows inside VM
But - base Chromebooks have 2GB RAM, 16GB drive, and Ubuntu install can take max 9GB, with free space about 8GB. I don't think WinXP can be installed into that small space... And all this for some stupid game...
