* Emulates all the oddities of the Inves Spectrum +: 64 KB RAM, RAM initialization with FF00H pattern, OUT ula AND RAM, EAR and MIC XOR, no contended memory, snow in border, colour ula delay, interrupt starts at end of top border (not at the beginning of the border), corrupt memory on every interrupt, no idle bus
* Uses Video drivers: X-Windows, SDL, Cocoa (Mac OS X), Framebuffer, ncurses, aalib, cacalib, stdout(console), simpletext(console)
* Uses Audio Drivers: PulseAudio, Alsa, SDL, DSP(OSS), CoreAudio (Mac OS X).
* Supports dumping audio & video to file
* Supports real tape loading of file formats: RWA, SMP, WAV, TZX, CDT, TAP, P, O. It handles loading of turbo load tapes or any type of tape loading for standard/non standard loading routines
* Handles binary tape format files (TAP, TZX, O, P, CDT) on standard BASIC ROM routines for ZX Spectrum, ZX80, ZX81, Amstrad CPC, Jupiter Ace
* Handles real audio loading (RWA, SMP, WAV) on standard BASIC ROM routines for ZX Spectrum, ZX80, ZX81, Amstrad CPC, Jupiter Ace
* Simulates real tape loading on standard BASIC ROM routines for ZX Spectrum, ZX80, ZX81
* Handles snapshot format: ZX, Z80, SP, SNA (loading only), P, O, Z81 (loading only), ACE
* Handles DCK Timex dock cartridges
* Emulates ZX Spectrum MMC Interfaces: ZXMMC, DivMMC
* Emulates ZX81 ZXPand MMC Interface
* Handles RAM, EPROM and Intel Flash cards on Z88
* Handles compressed formats zip, tar, rar, gz through external utilities
* Supports Quicksilva, ZON-X81, and VSYNC-based sound on ZX80/81
* Supports Speaker and Soundbox sound on Jupiter Ace
* Supports RAM packs on ZX80/81 up to 56 KB
* Supports RAM packs on Jupiter Ace up to 35 KB
* Joystick emulation with real joystick (on Linux) and keyboard cursors: Kempston, Sinclair 1&2, Cursor Joystick, Cursor & Shift, OPQA, Fuller, Zebra, Mikro-Gen. Autofire function also
* ZX Printer emulation
* Lightgun emulation: Almost perfect emulation of Gunstick from MHT Ingenieros S.L and experimental emulation of Magnum Light Phaser
* Kempston mouse emulation
* Supports Input spool text file to simulate keyboard press
* Supports reading Pokes from .POK files
* Debug functions: Registers, Dissassemble, Breakpoints (PC, Conditional, Peek), Step-to-step, Hexadecimal Dump, View Sprites, Find byte (useful to find POKEs), CPU Transaction log, View BASIC
* Accessibility support: Print char traps allows to capture generated text from almost any program or game, using standard ROM calls (RST 10H) or even non standard print character rutines. Can send generated text from a game to a text-to-speech program. It's ready for text to speech support for blind or visually impaired people. Menu emulator can be also read by a text-to-speech program.
* Simulates upper RAM memory refresh on Spectrum 48Kb, losing its contents when changing R register very quickly
* Other features not enabled by default on compile process: MEMPTR emulation, Visualmem menu, CPU Statistics
