Sonic & Knuckles Operating System (Real HW Capture)

Part of my PC smooth scrolling series. Shows off the overscan border of VGA and the Vertical Interrupt (yes, PC's can have those but only if you are lucky) with the Genesis "Color Dot" simulation at the bottom. This is VGA ModeX at 320x420. If VESA VBE was used with LFB, an enormous speedup in performance would happen BUT no overscan, and I need/want the overscan! ModeX is very slow and you need a Pentium 1 MMX at minimum 225 MHz, or a Pentium II at 266 MHz (yes, II was slower at video caching by default), or a Celeron at 450 MHz (low budget 400 CPU needs overclocking to 450). But why was Sonic & Knuckles Collection PC advertised running at 75 MHz Pentium? Because it couldn't keep up with the frame rate even with Direct Draw using LFB! I have optimized my code as much as possible and enabled fast writing for Pentium II, but it is difficult to gain any more performance. Remember that PC graphics cards by default are not hardware accelerated except for text mode. The Vertical Interrupt is not supported by many graphics cards out there, and is a relic from the EGA (when ISA was the default). My graphics card is an ATI Radeon 9800 Pro, and the computer have dual Intel Xeon CPUs at 2.4 GHz. There are no slowdowns with this much CPU power, but capturing at a smooth frame rate is extremely difficult/annoying, the original refresh rate of this card does 59.574 frames per second. YouTube will only scroll smoothly at 60 Hz so there is a translation (no frames dropped though), so that we can enjoy the smoothness.
