The SR, or "Super Revision", featured a number of improvements, including a much faster graphics subsystem offering a wider palette of colors, but the crown jewel of the SR refresh was the introduction of a brand-new sound technology for personal computers: FM synthesis.
FM synthesis is a digital synthesis technique for creating complex sounds by modifying a base waveform the carrier with another waveform the modulator. A short time later, Yamaha developed a range of 1-chip FM synth implementations suitable for mounting onto standard circuit boards.
Meanwhile, FM synthesis was also beginning to be used in some of the latest arcade games, such as Marble Madness, Ghosts 'n Goblins, and Space Harrier. Compared to the earlier programmable sound generator PSG chips like the APU inside the Famicom or the ubiquitous AY chip, FM synthesis produces smooth, glassy tones which are digitally flawless, but also complex enough to avoid sounding "chippy" or "beepy".
In essence, NEC brought the latest arcade-quality sound to home computers, and the difference was astounding. The other computer manufacturers rushed to catch up, and FM synth quickly became the de facto sound of Japanese computer games. The inclusion of FM synthesis, along with the much improved graphics architecture, redefined the PC series as a computer for gamers and creative hobbyists, and secured its position as the quintessential Japanese computer of the s.
The PCmkIISR and its successors became the primary target platform for the growing Japanese computer game industry, as well as the computer of choice for a generation of Japanese programmers, artists, and musicians. This model marks the repositioning of the PC as a system for hobbyists and gamers. A sleek jet-black model was also available. Featuring a bit CPU, up to colors, a video processor providing hardware-based scrolling and spriting, and a custom OS, the PCVA was a powerhouse of a system that was unfortunately plagued by compatibility problems, and ultimately overshadowed by the Sharp X V1 games will usually run in V2 mode, but with subtle glitches.
A common symptom of a V1 game running incorrectly in V2 mode is a washed-out bluish-green screen. Learn Japanese in Kobe. ILA has been providing students' dreams since Why choose ILA?

The X1 was sleekly built notice how the monitor, main unit, and keyboard are all exactly the same width , and was available in a futuristic chrome silver or a gorgeous Rosso Corsa red.
Original model, with built-in cassette tape data recorder, a 4MHz Z80A processor, and a display resolution of x effectively x with scanlines. A more powerful successor, enabling a x, 8-color hi-reso mode. Available with a tape data recorder or floppy drives. Fully backwards compatible with original X1 software. Bundled with a NES-style gamepad, called a "joycard". Also included a composite video out port for recording gaming sessions, for example. Another significant hardware upgrade.
Unfortunately, the turboZ series sold very poorly in the face of competition from other companies, as well as Sharp's own X, so there is very little software that takes advantage of the new features.
Note that the X1turbo is backwards compatible with pretty much everything, so it's easiest to use that. Like Sharp's earlier MZ series, the X1 adheres to a "clean design" philosophy. This means that there is no built-in operating system, only a simple initial program loader IPL. Note that on the X1, the first or primary floppy drive is called Drive 0, and the secondary drive is called Drive 1.
For games, movement is almost always numpad 4,6,2,8. Also remember that many games were designed for a joystick. The Xmillenium emulator has a joykey function that maps a virtual joystick to the arrow keys and ZX buttons of your physical keyboard.
