pcsx2 advanced options

[stefano]

Can anyone explain to me what it is the purpose of round modein advanced options?Whatever I choose there is nothing diffrent.....

Most games you won't notice a difference, some games that have stalls or lockups may get past with them.

They are not options that effect speed or anything else.

Round mode and all advanced options are covered in the configuration guide:
