FPGA Based Videogame System in Classic Console Discussion Posted December 6, 2020 14 hours ago, BrianC said: I have a TMSS model 1 with excellent sound quality and it doesn't have the rainbow banding that the Mega SG has when using composite via the DAC. S-Video looks awesome, though. Super NT doesn't have the issue with composite. Not every non TMSS model 1 has it (from what I understand anyway), but you're far more likely to find it in one of those. I'm fairly certain Kev used a non TMSS Genesis as the reference for the Mega Sg so he could emulate the sound of those systems accurately, and so apparently whatever that reference was had the rainbow banding issue as well. I wouldn't expect it from the Super Nt since the SNES never had that issue, nor would I have expected it to be an issue with the DAC. I'm not sure what component causes the banding or how big of an effort it would be to rework that piece, but I would have liked to see a model 2 as the source for video, and the non TMSS model 1 for the audio. I can't envision him going back and making what I would assume to be a major change like that at this point though, if it's even possible to frankenstein it together like that.
