If in your game, everything completes getting loaded before you start playing it, then you will not feel the difference. This is not a problem for all sorts of games. Thus, this is the major performance difference between the two formats. Loading data takes much longer when you load from a CSO. So for using CSO games, you can use the memory cards with lower memory capacities. The lag or slowing down is due to the fact that the system takes longer to search for files.ĬSO compressed games get loaded in your memory stick very easily as the games are usually smaller in size.

It doesn’t mean that the program is highly unstable at all times. Due to the compression, the program might not be as stable as the ISO format. But there is one problem with the CSO formats. So, many prefer CSO formats owing to the lesser space required. There are nine different levels of the compression in CSO files.Īs CSO is the compressed format of the ISO file, it consumes less space in the memory card. This method is also known as CISO at times and is the first such method for the ISO image format. The UMD games can be compressed using the CSO compression method. Actually it is the compression technique used for the ISO images. UDF files also are supported on the ISO images.ĬSO is a form of ISO image format.

Many software products and vendors support this image format. If you are not very familiar with these formats, read on for the details and differences between the two. The image formats ISO and CSO are very commonly used today.
