Hi everyone, I've never touched the HGSS games at all before, but I have a huge problem. Both during my original play (where I far exceeded even 200 days of continuous play days without messing with the clock) as well as when I tried to do the "11:59PM/Let clock roll over" method, Baboa just won't ever call me after I have received the third set of blocks. Naturally, this is really annoying. Is it possible to edit this somehow, perhaps in PkHex? I'm super, super bad with technology so I don't know the extend of which maybe hexeditors could do this without messing anything else up (and I'd probably ruin it, truthfully) but I just really want the safari zone to be upgraded properly. Thanks so much for any help!
