Lost black file due to corruption, need help if possible to make a new one similar to where I left off

[PapaHepatitis]

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.
