DEmul emulates games not just for Dreamcast, but also for the Atomiswave and NAOMI systems.
#DEMUL NAOMI EMULATOR FOR 32 BIT PC PC#
so I don't think this happens in near future. DEmul is a Dreamcast emulator that takes over from Chankast, another application to run Dreamcast games on PC which has now been abandoned. so saved picture must be exactly that size it was programmed.īut yes, there is known complex methods exists, which makes possible to use together "real" framebuffer and scaled picture, but well, they are complex and not easy to implement. Imo best example is "Sega Extreme Sports" - there really great sunspot effects, Vigilante8 also have nice "floating away picture" effect in menus, in "Silent Scope 2" now you can see scope picture at VMU screen (which are part of real picture readed from video memory), and many other games I forgot.īut if we have x10 picture rendered how we can save it to (virtual) GPU's video memory ? we can't, picture is too big, memory is too small. I hope this is not too complicated to understood.īut how Dreamcast emulators works ? they just do only steps 1 to 2, so they render picture and immediatelly show it on PC screen, whats all.ĭX11NG plugin do all 5 steps. will be set as source for video output and showed onscreen, with optional another hardware scaling. one or several frames later memory area from step 3. SH4 CPU can read or write some data to/from rendered picture (so called CPU framebuffer access)ĥ. 3.1 during storing "picture" can be scaled and/or "flicker-free" deinterlaced in hardware, color data converted to target format with dithering.Ĥ. GPU got "start render" signal and do scene draw.ģ. GPU got textures and geometry need to be rendered.Ģ. So how Dreamcast's (or almost any other) GPU works ? typically in several steps:ġ. 18:04:04:047 RL INFO +N/A Main - RocketLauncher v1.0.1.5a (18:04:04:112 RL INFO +63 Main - System Specs: RocketLauncher Dir: D:HyperspinRocketLauncher RocketLauncher is: 32-bit OS: Microsoft Windows 7 Ultimate SKU: Ultimate Total Memory: 8169.44 MB Free Memory: 5596.36 MB Used Memory: 2573. I'll try to explain in short what exactly new gen "NG" renderer have: Click to expand.well, mainly its because the way it works.
