Oh no that's fine. You don't have to. I think it works. At least it should now with the newer firmware. And yes RGB for the win. I have RGB cables for all my consoles that supports it. I'm not sure if I could do that RGB NES mod though. It feels morally wrong to steal the PPU from another machine haha. But composite looks surprisingly good on my Trinitron actually. And the NES was meant to be composite-only anyway! At least I'll keep telling myself that.
But man now you're making me feel a bit bummed out about having mostly PAL games in my collection haha. Well I already did feel bummed out about it so no worries.

It does suck about 50hz, but at least many if not most of them can be played on an NTSC console without any issues. The ones that were not PAL optimized anyway, which seems to be most of them. I'd love to have an NTSC-only collection myself, but I feel that it's a bit too late to start over now with these damn prices today. I do own a Powerpak though so if I feel like playing a PAL optimized game in 60hz at least I have that option.
And I collect what I can afford, so basically it's mostly cart only from various regions these days. I don't like to have boxes that have pressure damage and tears and such, so it would be even more expensive to get CIB copies in that case. Famicom games are usually much cheaper CIB though so if I can find a CIB FC game I'll opt for that. Usually they're also in better shape for some reason. The Japanese probably took better care of their games in most cases compared to the west.
Also I can totally understand not being a member on nesdb, especially if you only have NTSC games although they do discuss all kinds of NES collecting there. But yeah it is mostly focused on the SCN region games. And it can be a bit insular and circle-jerky there at times as well so you're not really missing much.
