PAL N64 with NTSC games, 61hz

[klm]

Hey Everyone,

I’ve been using my OSSC for the past six months and have been really happy with it. My Samsung T24E390 works well with my PAL SNES, Mega Drive, Saturn and PS2, supporting L2X and L5X modes. I just had my N64 RGB modded using Tim Worthington’s board and it works fine for PAL games. However my TV does not like the 61hz signal a PAL N64 outputs when playing NTSC games. I was hoping it would be able to cope since it does accept some resolutions at 67, 72 and 75hz.

I was wondering if there’s anything I can do with the OSSC’s settings that would maybe make the signal more palatable for my TV? Or is a refresh rate of 61hz something that’s either going to work or not regardless? Also, are there any N64 mods available that would make a PAL system output a cleaner NTSC frequency?

Normally I’d be fine sticking to PAL games but there’s a bit of a catch: L5X mode doesn’t work nicely with the higher vertical resolution of PAL optimised games. It ends up cutting of quite a lot of the screen. For black bordered PAL titles it’s actually a godsend, fixing aspect ratio and getting rid of black borders, but on N64, this only applies to a few titles.

This is the kind of problem that the Dual Frequency Oscillator was made for, but I’m not aware of anyone getting it working with the N64 yet.

My RGB modded PAL N64 does the same thing, fortunately my TV’s “sort of” OK with it. It doesn’t allow me to turn on game mode and/or resize the image, but works in Line3x. Would also like to know if there’s a workaround.

The SNES is a bit iffy as well… My OG model with a CSYNC cable usually runs solidly at 60.05hz and has no problems, my 1-chip with a sync-on-luma seems to fluctuate in some games between (about) 60.05Hz and 60.3Hz, occasionally causing drop outs.
