I've hex compared both gui version for r198 and r202 and they are identical. I have not had this issue. I've saved my CFG file many times on MASS USB. But I will keep an eye on this bug if I see others report this as well, so thanks for the info on this.
I wanted to learn if he is using the Network method to boot PS2PSXe, because GUI is not able to work with PS2Client and PS2Link. Yes, you can do the combo to go to the GUI, but you can't successfully make CFG saves or anything nor load more games from your network. It's not designed or never done to be compatible with Network/Host method.
So this is why I was inquiring his method to boot up the emulator. He didn't give me what I needed, so I could not provide anymore info about it. We'll just see when he replies to learn his method and etc. If people to supply enough information, it then makes it difficult to give them the right answer.
Maybe he is using a very old version of GUI, and he needs to make sure that when he installs mine, that it's a fresh install --the only thing he should keep is the
mc folder and
bios folder (as well as his game folder if he has them on MASS/USB) and the files inside. So his gamesaves don't get deleted. Also it would be important to learn which bios he is using? He should only use the one that
ffgriever recommends:
scph7502.bin -- that could also improve his situation.
