"4. PAL Protection
The following info was submitted by mark_k@iname.com:
Most later SNES games contain code to check for a 60Hz or 50Hz
display. The NTSC TV system displays 60 frames per second (60Hz).
The PAL system displays 50 (50Hz). Later US and Japanese games
check for 60Hz, and thus fail to work on PAL consoles, even with a
universal adapter. They display a message like: "THIS GAME PAK IS
NOT DESIGNED FOR YOUR SUPER FAMICOM OR SUPER NES." Similarly, later
PAL games check for 50Hz, and thus fail to work on NTSC decks. Some
examples of games with a 50/60Hz check are Super Metroid, Pop 'n
TwinBee, and Super Mario All-Stars.
There is a way to get around this though. You can fit a switch to
your console, to choose between 50Hz and 60Hz displays. With this,
you can play all games. For example, let's say you want to play a
Super Metroid PAL cart on a US console. You would switch to 50Hz
before turning on the console. Once the title screen comes up, you
can either remain in 50Hz mode, or switch to 60Hz. The game only
does the 50/60Hz check right at the start.
Fitting a 50/60Hz switch is in my opinion essential for owners of
PAL consoles. Normally, a PAL console plays games 16 2/3% slower
than an NTSC one, with large black borders at the top and bottom of
the screen. In 60Hz mode, it plays just like a US console;
full-speed, full-screen.
I have yet to write a document describing in detail how to fit a
50/60Hz switch. But in my SNES lockout disabling document (on my
web page; see below), I give the URL of a picture which tells you
which pins to switch. But don't attempt this unless you have some
soldering experience!
Eventually, I will write a "step-by-step" guide to adding a 50/60Hz
switch.
URL of my page is http://www.netcomuk.co.uk/~markk/index.html "
helaas doet de link op het eind het niet. Maar een oplossign blijkt wel het bouwen van een 50/60 Hz switch. Weet iemand daar toevallig wat meer van?

Ik heb wat gevonden op mijn US/converter/PAL SNES probleem waar Notorious_Roy ook wel misschien in geintresserd is:-knip-
Daar ga ik ook ff wat meer over zoeken ! Thnx!
Toen ik dit las schoot me het opeens te binnen.
Ik heb mijn ouwe SNES (die ik dus verkocht had en waar al die US spellen het wel op deden) om laten bouwen bij de lokale videotheek. Dat ik dat vergeten ben.
Dat ombouwen zal dus wel deze 50/60Hz switch zijn geweest, ik kan me alleen geen schakelaar op mijn SNES herineren. Ik zal het eens bij die videotheek vragen of ze nog weten wat hun er mee deden.
