Its hardware supported multi\u2011layer scrolling, hardware sprites, and up to 61 simultaneous colors from a 512\u2011color palette, creating the fast, fluid visuals Sega famously dubbed \u201cblast processing.\u201d<\/p>\n\n\n\n<p>Beyond its technical prowess, the Genesis defined a generation through its distinctive sound, from the Yamaha YM2612 FM synthesizer and its vast library of action\u2011packed titles. The console maintained ties to its predecessor with optional Master System support, while select cartridges like Virtua Racing featured the custom Sega Virtua Processor (SVP) chip, pushing early 3D polygon rendering into console gaming years before mainstream 3D hardware arrived.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Manufacturer<\/strong>: Sega<\/li>\n\n\n\n<li><strong>Type<\/strong>: Video game console<\/li>\n\n\n\n<li><strong>Release Date<\/strong>: 1989<\/li>\n\n\n\n<li><strong>Cost at release<\/strong>: ~$500 (adjusted for inflation)<\/li>\n\n\n\n<li><strong>MIPS<\/strong>: 6-8<\/li>\n<\/ul>\n\n\n\n<section class=\"w-screen px-6 cu-section cu-section--white ml-offset-center md:px-8 lg:px-14\">\n    <div class=\"space-y-6 cu-max-w-child-5xl  md:space-y-10 cu-prose-first-last\">\n\n        \n    \n    <dl class=\"cu-description cu-component-updated\">\n        \n    <div class=\"grid pt-4 pb-3 border-b accordion border-cu-black-100 md:pt-6 md:pb-5 first:border-t\">\n        <dt class=\"font-semibold not-prose\">\n            <button class=\"flex items-center justify-between w-full text-left accordion__button\" aria-expanded=\"false\" aria-controls=\"accordion-hardware-specifications\">\n                <span class=\"flex-1 ml-auto text-left break-words whitespace-normal cu-icon\">\n                    Hardware Specifications\n                <\/span>\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" fill=\"none\" viewbox=\"0 0 24 24\" stroke-width=\"1.5\" stroke=\"currentColor\" aria-hidden=\"true\" data-slot=\"icon\" class=\"w-5 h-5 ml-auto transition-transform rotate-0 accordion__icon text-cu-black-500\">\n                    <path stroke-linecap=\"round\" stroke-linejoin=\"round\" d=\"M8.25 4.5l7.5 7.5-7.5 7.5\"><\/path>\n                <\/svg>\n            <\/button>\n        <\/dt>\n        <dd class=\"p-0 mt-0 cu-prose cu-prose-first-last accordion__content md:p-0 md:mt-0\" hidden=\"\" id=\"accordion-hardware-specifications\">\n            \n\n<ul class=\"wp-block-list\">\n<li><strong>CPU<\/strong>: Motorola 68000 16\/32-bit at 7.6-7.67 MHz (NTSC), paired with Zilog Z80 8-bit co-processor at 3.58 MHz for sound and backward compatibility.<\/li>\n\n\n\n<li><strong>Memory<\/strong>: 64 KB main work RAM (68000), 64 KB video RAM (VRAM), 8 KB audio RAM (Z80).<\/li>\n\n\n\n<li><strong>Graphics (VDP)<\/strong>: Yamaha YM7101, up to 61 on-screen colors from 512-color palette, hardware sprites, scrolling;
