Overkill, much? :-)

Then again, I got a giggle out of bit-bashing a VGA signal!

You know, what I'd like to know - speaking of fast processors doing 
oldish stuff, is why the BBC emulator on Android is talking about the 
speed and needing, like, a GHz phone.

I recall 65Host (which, granted, wasn't a 100% accurate emulation) 
working just fine on a 25MHz machine. CLS was a little slow, otherwise, 
it seemed okay.

I've also used either BeebEm or the other one (forget the name) on a 
466MHz Celeron, and it seemed okay. I can cope with 30fps instead of 50 
if it "feels" fast enough!

But for a mobile phone they reckon a gigahertz is necessary? It *really* 
takes 1GHz of ARM power to emulate a 2MHz computer? Or is Android just 
really wasteful of resources?


On a different note: http://www.littlefluffytoys.com/?p=406 suggests 
that BeebDroid (for Android, in alpha test) is a port of their favourite 
open source emulator. It isn't stated which, but both BeebEm and B-Em 
are GPL. I wonder if they will honour the GPL? I'd be interested in 
seeing how an emulator is adapted to a mobile phone!


Best wishes,

Rick.
