snes/N64 VGA box

[deadpool18]

Has anyone tried playing either an SNES, N64, or even an NES on a VGA monitor.   I have an old VGA LCD monitor laying around, and I was thinking of building a bartop with either a N64 or a Retroduo (snes/nes clone).

I saw this:

which works on N64/SNES/Gamecube according to the box.  I realize that it won't work with the Retroduo (only standard RCA/S-Video connection) and I have no interest in building a Gamecube bartop.  However, I have an old N64, LCD monitor, and a Madcatz Arcade Shark joystick.  I thought it might be a fun project to build a bartop with those components.

My main question is, how will the image look on the monitor?  Will it be too blurry or pixelated.  I'm also interested to know how snes/nes games would look on a vga monitor if I buy a different adapter.  Does anyone have any experience directly connecting (not through video card or emulation) one of these old consoles to a computer monitor?  Thanks!

n64 runs at 15K like a arcade monitor so it will require a converter or vga adapter but I am not sure what the outcome would look like.

NES only does RF or composite output right?  That's gonna look pretty terrible on a VGA display.  I think it'd be far easier to put together a cheap 500-1000mhz PC and emulate it.  I have however read that you could swap the PPU on an NES with that of a Play Choice 10 arcade board and the NES will then output NTSC RGB video instead and that'd be compatable with what ever arcade monitors the PlayChoice's used.  But emulation sounds a LOT easier.
