Look at this bootleg 3 in 1 Collection:

3+in+1+Toy+Story+(Buzz+Lightyear,+Toy+Story+2,+Toy+Story+Racer).jpg



This is the type of screen you would get upon boot:
Dragon+Ball+Trilogy3.jpg

My question is, how would you put 3 500- 700mb games onto 1 disc?? Is there a certain tool??

I highly doubt each game is anywhere near 500-700mb AFTER dummy data and padding is removed.

DBZ is 52mb dl (zipped)

It's probably just a custom basic binary selector, choose which bin, and launch.

Download/RIP any 3-in-1 you can find and examine the structure. Swap other games in/out and I bet you can hex edit the selector to change the names.

Someone has uploaded a Dragonball 3 in 1. I'll burn it to a CD/Virtual Drive to see the contents of the iso.

Most archive managers (like 7-Zip) can open ISO files directly. You don't have to burn it first.

I remember the 3-in-one games, I had one that combined Crash, Crash 2, and Crash 3 onto one disc so i could play it on my PSP as the ISO was smaller than just Crash itself due to dummy data being absent.

I remember those disc's from back off the day.
I think they rip most off the CDDA music (just normal audio tracks), replace movies with dummy files to save space.
Little the same thing as those Twilight warez cd's ;)

Well, the Crash multi disc managed to not do that. I am not a fan of rips like some are but it is nice to have multi-game discs where all the content is there.

a quick google reveals that toy story racer iso is 122meg, presuming the others are similarly sized you can fit them all on a disk easily, without any compression.

Back in the xbox days it was really easy to take the game files from a game iso and build a disk with 3 or more games on, some budget games were less than a few hundred meg, and often games had video files on the disk multiple times in different languages which could be deleted without a problem if you never changed the language setting on your machine.

it's possible, but it's complicated. the problem is the lba. I'm not sure if they're ps1 or 2 games, but I have cubic lode runner and ultraman on one disc, and it was a pita. I've seen up to 10 games on a disc. I think I still have the photo of this:
