how do i make a modded ps2 game when the game is separated into parts?can i put them on 1 disk to make the full game?
Some large downloads are split into smaller pieces. The programs you use to extract them will combine the pieces into a single file. If the separate parts you are talking about are BIN, ISO, CUE, SUB, etc. then you just need to use a good burning software and it will use all the image pieces to create a copy of the disc. The different pieces contain actual disc data, subchannel data, and information about how the data is organized on the disc.
What ever program you use will put the separate archives together. Just extract the first part, and it will do the rest.
if the files have no logo and you're not sure how to open them then try downloading WinRAR. Just open the first file out of the parts and drag it to wherever you want, it should automatically extract from all the different parts without you having to do anything extra. You just have to make sure that all the parts are in the same folder before extracting.
