File .sav of HG/SS with Trainer House data

[Dancand]

Hi all!

I’m trying to discover the offsets of the file saving where there are Viridian City Trainer House data in pokemon HG/SS.

This data should be in a non zero bytes batches only if the player has a battle with someone who connects with through PokeWalker. In this case an NPC character of the rival player will appear in Trainer House at Viridian City near the default trainer Cal. I would like to edit these trainers giving them very competitive teams to make the game more challenging beyond Battle Frontier.

Unfortunately this is the first time I play (after more than a decade) Pokemon SS on Delta emulator on my smartphone, so I never used this interesting feature. 

If someone had a file .sav with this stuff would be warmly appreciated.

Thanks!

I worked on this a long time ago but forgot to register. I'll send you my save file (100%!). It has an NPC in the trainer house. One way to find the offsets is to search for the team that's in that NPC (for example, look for Garchomp). If you make any progress or manage to fill the trainer house with trainers, please share. Good luck.
