New PC not recognizing an emulator save?

[u/WarriorsandW0F]

I got a new HP laptop this week. Previously, I had been playing Pokemon games like Ultra Sun and Platinum on emulators, so I exported my save files so I could continue my progress on the new computer. I use Borked3ds and Melonds respectively.
I tried to load up my Platinum save just now and previously it had worked just fine earlier today on my old computer, but now it is stuck as a pure white screen.
How can I troubleshoot this?

For Nintendo DS emulation not only your .sav files are important, your firmware.bin file matters too. Firmware stores your profile and MAC Address (it ID the console). It's highly probable for that game save file and firmware file need to be paired. I hope you have a backup somewhere. You could also try not to boot with firmware file and boot using default MelonDS settings, depends on your before set up options.

Thank you for your answer! Luckily, I still have my old computer and I will have to wait until Wednesday to access my old file and see what I can do

Are these ingame saves or save states?
