## Low Latency
The display produced is an emulated CRT, with phosphor decay. Therefore if you have a 140Hz monitor it can produce 140 distinct frames per second. Latency is dictated by the output hardware, not the emulated machine.
@ -74,10 +71,8 @@ A corollary of emulating the continuous nature CRT, not merely performing end-of
Cycle-accurate emulation for the supported target machines is fairly trite; this emulator seeks to follow that precedent. All emulation logic is written in C++ for explicit control over costs but, where a conflict arises, the presumption is towards clarity and simplicity of code. This emulator is willing to spend the processing resources available on modern hardware.
Self-ratings:
* the Electron, Oric and Vic-20 are pretty much perfect;
* the ZX80, ZX81, ColecoVision, MSX 1 and Apple IIs are very strong;
* the Master System is almost perfect, access windows and CRAM dots and all the rest, but further work is required on some small aspects of behaviour;
* the Amstrad CPC has known accuracy deficiencies in its 8272 and 6845;
* the Atari 2600 has some known accuracy deficiencies in its TIA;
* the C-1540(/1) is locked in reading mode and doesn't yet support writing.
