Does this version (Cgminer 4.12) not support local solo mining? (i.e. CHTA or NENG)
NENG is script not SHA-256 so won't be able to run on that coin.
Currently with CHTA I've only been able to have it running when pointing towards a pool, haven't been able to get it solo mining yet - so am another from the CHTA community patiently waiting for the future update which would hopefully allow this!
