Can emulators run 'accelerated' like Spectrum NextI saw a video of the Spectrum Next running games in 'accelerated' mode (7Hz) -- Hard Drivin' was one of the examples. This gave a smoother framerate …
JSpeccy can play the games up to x10 faster, but it meets the Spectrum behaviour, one interrupt every 69888 (or 70908) t-states. Could be possible to generate one int every N frames, but not all games tolerate these behaviour. -
Fastest emulator screen renderingHi, I'm developing an algorithm for fast emulator screen rendering and here is what I came up with. 1) Use 4bpp indexed image format as target …
