How A PS2 Game Works

A PS2 looks for the DVD/CD. Once found, It looks for the SYSTEM.CNF File. This file is the most important file on the ps2 game disc. A typical SYSTEM.CNF looks like this;

BOOT2 = cdrom0:\SLUS_201.74;1
VER = 1.00
VMODE = NTSC

That is for Rumble Racing. In fact, It is bcos of this game I created this blog. It works in such a way that it first decides the region (if its NTSC or PAL). If the ps2 is NTSC, and the SYSTEM.CNF reads NTSC, the game boots. The SYSTEM.CNF File then tells the PS2 to boot a certain file (the SLUS_201.74;1). This file tells the PS2 what, when and how to boot files in the DATA folder and MODULES folder. There is also a GLBDATA.PS2 file. Im not so sure of what it does. But it has a use.
