PapaHepatitis

I've tried with a friend of mine whos good at it, barely anything could actually be salvaged, the file just killed itself for no reason, It might've been a dodgy rom

the save file I'd like to request is fairly simple, I just recently entered Nimbasa city with a team consisting of:
Servine - 25 - Overgrow
Sandile - 25 - Moxie
Palpitoad - 25 - Swift Swim
Conkeldurr - 25 - Guts
Drillbur - 25 - Sand Force
Darumaka - 25 - Hustle
I also had any items you could obtain normally up until that point
HMs, TMs, etc
I also had up to the 3rd badge, I hadn't defeated Elisa yet, Just N at the ferris wheel
If anyone needs any more information, I can be found on discord @PapaHepatitis#7170
If anything this sophisticated isn't possible I can also settle for something a little less
I would also prefer this be on a DeSmuME emulator, however any emulator that runs Pokemon Black is also fine

Like the title says I recently lost my save profile on a DeSmuME emulator for Pokemon black and was wondering if anyone here could help me create a new save around where I left off in terms of in-game progress and if that's even possible, I'm very new to any of this stuff so I have no clue if its even possible to tweak what is unlocked and what isn't, I just want to see if there's a sliver of hope I haven't lost all of my progress and have to start from scratch. Thanks.
