Yeah, it will work fine if you program them via ISP - just no support for their USB thing.You probably won't even need to do burn bootloader with my core; the first time you program via ISP, it will erase the bootloader, and there aren't any fuses specific to their bootloader, since there's no hardware bootloader support on the tiny85
Then it´s my turn now.
I ported my program that was on TinywireS to your nested Wire.h and compiles ok with your core, I would like to have Software serial also and have a console on such a tiny amazing chip also..
Hope I can upload now..
Will ask if I get stuck,
Thanks again
