WHy? Because with a Game Enhancer you have to place an original game or demo in the psx let it spin for 5 seconds until it stops and replace it with the backup/import. With a mod-chip you just pop a game in and play. I have a Goldfinger and was getting VERY annoyed by this. My friend gave me a modchip "stealth" for $10 . . . BUT for some reason it didnt work in stealth. So i soldered it on as a regular chip and it works and I can use a free downloadable and burnable game enhancer cd which i hear defeats the anti-mod protection PLUS i think i can use my game enhance along with the chip. This was my first time soldering anything and it worked out fine "did it 2day". So if you want convienience then go for a chip. If you are a cautious person and think you would suck at soldering and dont mind swaping then go for a game enhance "the stealth works with ALL games"
