 genesis - メガドライブ / Genesis (US版, NTSC) | ||||
| 概 要 | HLSLでNTSCが不正確。 | ||||
| 詳 細 | Trying to get HLSL's NTSC emulation to look like my Genesis Nomad and Japanese Mega Drive's composite output, I noticed that the "rainbow effect" looks more saturated than real hardware and its position seems to be a bit shifted (which might be related to https://mametesters.org/view.php?id=6892 ?). Best game for testing has to be Zero Tolerance, which shows some (accidental?) "holographic foil" effect on the title screen when using composite NTSC video (the effect isn't visible over RGB or on PAL systems). | ||||
| 再現手順 | -First load zerotol under the Genesis or Mega Drive system, using -video bgfx -Then, in order to get clean screenshots comparable to what you'd get on real hardware captures, configure HLSL like this: ----Effect: hlsl ----Shadow Mask: white ----Enable NTSC: On ----NTSC A Value: 0.00 ----NTSC B Value: 0.00 ----Scanline Duration (uSec): 47.7 ----Phosphor Persistence, Red: 0.00 ----Phosphor Persistence, Green: 0.00 ----Phosphor Persistence, Blue: 0.00 ----Scanline Amount: 0.00 -Then just wait for a bit for the title screen to show up. | ||||
| 追加情報 | I'm including direct video captures with both a generic Scart to HDMI adapter and an OSSC, for reference (all of them adjusted to a correct 4:3 aspect ratio): NTSC composite: NTSC RGB: PAL composite: PAL RGB: | ||||
