Wrechid is correct, client side is gshop.data & gshop1.data. Server side is gshopsev.data & gshopsev1.data. They are NOT the same (binary) files. So they cannot just be renamed/copied, you HAVE to use a gSHOPeditor that can edit/save both differing client and server side files/formats. I have many included in PW_DEV.iso. For v146 I would probably recommend the one found in /PW_DEV.iso/1.5.x/gSHOPeditor by Luka/GitHub/GShop Editor By Luka.exe. Yes, I know, it's in the 1.5.x directory, but, that is only because of the timeframe in which it was added to the PW_DEV.iso; which means it WILL (also) work for 1.5.x, but if I'm not mistaken that is the editor I used to blank out all of the gSHOP files for the release! But if you have any problems with that one, I would next recommend to try any gSHOP editor you see in either the "1.5.x" directory, or the "1.4.4 - 1.4.5" directory. I do believe the one in the base/root PW_DEV directory (sGSHOPedit) is for older game versions only (it's the one of the original PWTOOLS from Ronny). The one (sGSHOPedit) in "pwtools-bin" may work too though, as that's a newer (newest?) version of Ronnys PWTOOLS... .. .
I'm not sure if I could recommend using any such .BAK gshop you find laying around in PW_DEV or with their respective gSHOP editor. You can double check it to see if you'd like to use it but, my best recommendation would be to just create a brand new one, that you can specifically cater to yourself! Just start with the client side, then don't forget to "export" or save the server side too!
