It depends on how Opera was coded. It probably wouldn't work though. But, it could be very beneficial for a homebrew web browser.The FPGA will be connected to "whatever" and always be running, so I suppose it can do whatever the actual cart connections can let you do (sounds jibberish but sorta makes sense). You could also have the FPGA running as a second DSP/Processor... doing what is upto the imagination (3D, MPEG decoder, full blown emulator of ?)
I wonder how big a memory space it could be configured to pretend to be? I'm thinking opera browser without needing a slot 2 card.....
Yeah...and other things for that matter, ds linux etc
