installing of sh4 patches

[k9andro]

Hi to all, new to this game. I have just bought the original and there are no updates to it, on the actual cd.
I see that there are 4 patches. Do you have to install all of them,,, or will just installing 1.4 fix all the previous bugs that 1.2, 1.3 fixed? Thanks for the help.

You only need to install the v1.4 patch. It contains all the previous updates from the previous ones.
