i dont know about switching gyms. how would you switch that? is it like, you switch the door warps to bring you to another gym? you walk into brocks gym but end up in blanes or would you just have someone else standing in brocks gym? cause that might just look weird and all.
personally, if you want to change something about the gyms, i'd rather have additional trainers and stuff. like, apprentice leaders... i'd be funny if you had to battle like, winona in falks gym, before you can battle falk at all, or tate and liz in the psychogym and that fat old guy in bobs etc. you know... similar to the special trainers in black/whites post game
As a general question, is it even possible to add new trainers into these games? Or is it still just editing existing ones?
I'd be switching the warps, yeah, and the text changed to reflect the new position (as well as the music that plays in the Gym Leader fight optimally). All of the gyms except for Blaine's look the same on the outside so it wouldn't actually appear
that odd.
It would help if I could have new trainers that actually walked towards you if they saw you ;-; But that unfortunately never worked. I could certainly put in team references of some sort though, I suppose...
Well, there's plenty of unused trainers so I have plenty to edit that way (although I've used up a fair few of them already). I'm not actually sure if you can add new trainers or not; I don't see any reason why you wouldn't be able to but I haven't tried. The only potential issue is naming the new trainers, but that might not actually be a problem.
I was wondering the same thing, but now I have another question, what if I'm using a really old version of the Sacred Gold and I said no to the lighting house? Will I not be able to do something later on?
Well, there's only an issue in the first place if there was a Kimono Girl blocking the Ecruteak Dance Theater. If there wasn't, then you don't need to worry; nothing will have changed.
edit: I've made a little progress on bug finding. Two things to report;
1) The MooMoo milk problem I believe is being caused by an erroneous overworld file. If it's what I think it is, this should be simple to fix.
2) It turns out the reason for fishing up missingnos was a problem with PPRE. Every area has data that causes a certain Pokémon to appear at night when fishing with the Good/Super Rod. Olivine City is a good example; in the original game you will see Corsola during morning/day, and then Staryu during night. Now, the issue is that PPRE doesn't actually display this data, and just shows the fishing list for morning and day.
Hence...
The good news is that the glitch won't affect you at all if you fish during morning and/or day. Since I have not distributed water-based Pokémon dependent on time, there shouldn't be an availability issue.
The bad news is what's actually happening; PPRE (the program I use for script editing, Wild Pokemon editing, Pokemon editing and trainer editing) is completely chopping this data off! Hence every single wild file is four bytes shorter than it should be, and due to this missing data at night, it's what causes the Missingno to always pop up. This means it is fixable, but it's going to be a long and very tedious process; I might leave it for another time, since I'll have to go through all ~141 files and add the necessary bytes in (although, only if they're necessary, so that cuts it down a bit).
Nice to finally know
why that's occurring though. The problems of not just using hex...
