I don't know a whole lot about console modchips, but I do know a bit about soldering. When soldering pins on most ICs (chips like this modchip) there are a few basic things to keep in mind.
While you would be best off with a smaller-than-average tip and variable heat, you should be able to pull it off with a standard one, so long as the tip isn't too fat/dull to only touch one pin at a time. When soldering ICs you need to make sure as little heat gets to the chip as possible, as too much can destroy the chip. Make sure you use solder with a high tin to lead ratio; more tin means it melts faster, meaning less time for heat transfer. A heat sink clamp can help, but isn't essential if you have a decent amount of soldering experience. If you need to desolder anything make sure you've got some solder wick (or even better, a "solder sucker" like this one) to draw off the old solder.
"I think that the problem with this video is it is highly derivative of many popular bands within the genre. Although when viewed on its own merits, it does have a deeper groove. However what it has in groove, it lacks in originality. One can't help but be reminded of such bands as Pearl Jam, White Zombie, Suicidal Tendencies and other bands that bear the mantle of so called "Alternative Rock". One is even reminded of Lorie Anderson when she wore curlers. Hehehmhm! This video speaks less to the heart and more to the sphincter. In closing, I think Korn would do well to learn more from -"
