To be honest I think the GCW-Zero still has a bucket of life left it.
I hope so. Always switching to the latest device doesn't help release quality.
Having a smaller number of changes would make it much easier to implement than having to do everything from scratch.
Must more likely to be successful.
I agree but for me, a fully functional device would be perfect. I don't need hardware improvements, that just drains more energy. The current hardware is theoretically not much less powerful than the 3DS, but the current drivers doesn't make it possible to fully use its capabilities.
I know that for emulation of some more recent platforms, a strong CPU is needed. In this case forget the Ingenic JZ47XX CPUs, they are very good for energy consumption, but they are very weak compared to an ARM Cortex A9. But well used they are still very nice, at least for my needs.
