Ive seen both online, the website you posted has each working for snes but the 4.5 does n64 an 3.8 does nes?
3.8 mm is for opening NES, SNES, N64, Gameboy, and Gameboy Color carts.
4.5 mm is for opening Master System, Genesis and 32X carts. Plus SNES, N64, and Gamecube systems.
There's probably a few more, but if you were to get both gamebits, an ordinary philips screwdriver, and a tri-wing screwdriver, you'd be able to open up just about every retro game and console.
