got console, and I want to say a few words about emulation and sound lag.
I compare *oid (nesoid, gensoid, snesoid) and .EMU (NES.EMU, MD.EMU, Snes9xEX) emulators.
All .EMU emulators have a big sound lag (0.4 - 0.5 sec) but the worst thing, that they have input lag (0.1-0.2 sec) ie action occurs with a delay after key is pressed (for me it makes emulators useless).
*oid does not have a sound lag (or very small <0.2 sec) and does not have input lag. ie sound lag is a software problem. (not hardware)
but *oid works less smoothly than .EMU. especially Sega, and for *oid you can not disable linear smoothing/interpolation.
used "1 GHz" ICS, the latest versions of the emulators.
also I could not find a good ZX Spectrum emulator, which works with hardware keys. Xpectroid seems is the best variant. But it has a big lags during work (~ big lag every second). Can someone test it on Android 2.3?
sorry for bad English.
