Been playing the nes on the 1080,. would like a cleaner sharper pic, scanline and other options are a plus etc.
If you want to get cleaner video out of an NES, some of the RetroTINK products have "comb filters" intended to clean up the composite signal a bit, but it won't be performing miracles. If you want nice, sharp pixels coming out of your NES, I've got 3 options to mention:
1) NESRGB mod. This mod will give you nice, clean pixels at the system's original 240p resolution by adding RGB capabilities to the original system. This requires purchase of a special mod kit from Tim Worthington, the mod's creator. If you are unable to install the mod yourself, then you will also need to hire someone to install it. Luckily, there are no shortage of skilled installers. During installation, most modders will allow you to tweak your install with upgrades like a Nintendo multi-out port so you can use HD Retrovision's SNES cable, the ability to toggle between different color palettes, and more.
2) Hi-Def NES HDMI mod. Similar to the NESRGB mod, this mod adds the ability to your NES to output crispy, clear pixels via HDMI at 480p, 720p and 1080p, with the added bonuses of having WAY more "behind the scenes" options available to you. However, GametechUS, who distributes these boards, is currently sold out of their stock due to one or more of the required components to build them no longer being produced.
3) AVS system. It's an FPGA-based console like the Analogue NT, but available at a fraction of the price. It goes up to 720p via HDMI and is compatible with both NES and Famicom carts. It looks very nice; I nearly bought one myself but decided to go with an NESRGB install instead.
All of these options are going to cost a considerable bit of pocket change (especially the Hi-Def NES board, if you can find it, since it's not being produced for the time being). If you go with the NESRGB, you will still need an OSSC or RetroTINK to transcode the analog signal to HDMI, but it will look great. If you get the AVS, you can just plug directly into your TV, but you'll still want to pick up an OSSC or RetroTINK for your other consoles.
As Olmec would say in 'Legends of the Hidden Temple', "The choice is yours...and yours alone!"
Speaking of, here's the proposed new setup. Just got to get the Dreamcast cable and get my N64 modded. I might look into getting the PC Engine Duo-R modded and I need to see about getting the Game Gear switched over to S-Video. Everything else will probably stay as is unless the NES mod gets cheaper.
Looks good. The Dreamcast cable is my last holdout as well. Way easier for me to just deal with a full YPbPr setup.
When you get your N64 modded, go for the Advanced version of the board and have it flashed with borti's firmware that allows you to toggle disabling of the N64's internal antialiasing. It really helps to clean up those visuals.
