PAL SNES 60HZ mod: without switch possible?

[Highthorn]

Hello all,

I'm in the process of modding my pal snes to 60hz.
I already lifted pins 24 & 30.

I'm following a guide that involves putting a switch in between the wires and the voltage regulator.
Because I only find guides involving a switch and only some random posts here and there on modding without a switch.

As I only use a everdrive to play the games (some on display) I was wondering if I could mod it without a switch and have permanent 60hz?

Could I just solder the wire from pin 24 and 30 to ground or will it still involve putting a 2.2kOhm resistor?

Thank you in advance.

Yeah, whichever connections the switch brings together when it's in the 60Hz position, just connect them together directly without the switch. If a resistor is part of that circuit, then include it.

The Switch is recommended because not all games works fine with the mod, so you need a way to temporary disable it.

Changing the clock can mess some software.

Another option for a switchless mod is the supercic mod (It uses the reset button as a mode switcher (PAL, NTSC, or Auto), removing the need for another switch to be added).

Ah ok, got it.
But would it also be a problem when only using NTSC roms?

I can not tell, may be not, because all software is designed to use 60 Hz.

The switch is there in case you still want to run PAL games. If NTSC is all you want, then you really don't need the switch.

Thank you for the help, it works fine with an Everdrive!

Not that you should go in and change it now that it works, but there's a lot of points to get ground from closer than that :v

 

[Highthorn]

Yes you're right, I believe the whole outer metal plating of the mainboard is ground but just to be sure.

I think the most convenient there would be pin 64 on the S-WRAM.

I yet have one more question just out of curiosity.
(If I say this correctly) my everdrive now recognises my snes as NTSC, as pal roms don't boot and NTSC roms do, which is perfect for me.

If I now also lift pin 4 of the lockout chip and ground it, my pal cartridges will work again, correct?
Or will the pal cartridges be forced to run in 60hz with messed up speed?
(I understand that this is the reason to built in a switch but was just curious).

The PAL cartridges would "run", yes, however in most games you would get a "This game pak is not designed for your Super NES" message, because they check if the console runs in 50Hz at bootup.
