Apparently the game was released as a cd-rom. I discovered that because it was on the list of PS2 games that use cd's and the cd art doesn't even mention DVD.
The thing is, the game is 1.8GB.
I was thinking you are mading things up but i checked and it's true.
Anyway try running file thru emulator because even if you're pc is shit (like me) you can at least check if the game works.
Btw what file exstenaion does it have?
Oh my goodness!
Your act is similar to put a truck inside your pocket. Better forget your nice plan.
There are other solutions to play Lego without DVD/CD.
aren't cds around 700-800MBs, yet the game you made a disc image of was over a GB? sounds like the cd version either was modified or something went wrong while ripping the disc.
