Help Wanted!

Coming Attractions/Works in Progress (which I may or may not ever get around to completing)

When I get time, I may write documents on the following subjects:

• Super NES "PAL booster" modification instructions. This will only be of use if you own a PAL booster. Performing this modification to your console will allow the 50/60Hz switch on the booster to work. Note that this is not the same as fitting a 50/60Hz switch inside the console! There is a brief explanation of how PAL boosters work in the Tri-Star Super Game Boy modification document.
• NES game compatibility list. This will list which PAL NES games do not work perfectly on an NTSC NES, and vice versa.
• Sega Mega Drive/Genesis 50/60Hz and language switch instructions. This is covered in the video games FAQ at ftp://rtfm.mit.edu/ for the Mega Drive/Genesis 1. Hopefully I will find out how to fit switches to the Mega Drive/Genesis II also.

If you want information on any of these right away, or have information to contribute, contact me.
