I like the idea that someone takes over the handy development and fixes the bugs, crappy sound etc which are still in.
Even in the nevest version there was a bug in collision of scaled sprites and the out of screen bits.
And, a improved debugging version would be very welcome.
But... I think it would be much much better to continue work on the sdl port, as this is the one which is used on all other emulators (mednafen), machines and handhelds. Actually, with handhelds it really makes sence to improve the comlynx over udp of handy. Anyway, as long as the development will be only for one or two systems, I will not invest my time, sorry.
