I think a hd60 should work I’m sort of new to this n64 recording. One problem I had a lot was having the capture card recognize the console. I had to adjust the rca cable a lot to get it to work.
I also figured out that I have to have the console off then once the software is open up I turn it on other wise it won’t recognize it.
I tried to get it to the standard tv resolution but it won’t go back it’s really finicky!
Here’s the rca converter I got from Best Buy: rca converter
Also here is a cheaper one on Amazon that also works but the design sucks and you would need a USB adapter to power it:
RCA to HDMI, AV to HDMI Converter, DIGITNOW 1080P Mini RCA Composite CVBS AV to HDMI Video Audio Converter Adapter Supporting PAL/NTSC for PC/ Laptop /Xbox /PS4 /TV /STB /VHS /VCR /Blue-Ray https://www.amazon.com/dp/B087TR4M23/ref=cm_sw_r_cp_api_glt_i_WBA5TH8KT1HJNQSVNTGY?_encoding=UTF8&psc=1
Hope this helps!
