If you're talking about editing a save game, that depends.
If you want to run an exploit from a digital title, easier said than done due to how you need to first decrypt the save before you can modify it, and then encrypt it. This process requires an entrypoint all its own.
If you want to run an exploit from a game cartridge, this is easier to do because there's no console-specific save encryption to worry about, but you need some sort of tool to load the exploited game save onto the cartridge like a save dongle or another exploited system.

We can't do that using a save manager app?

U can get a ROM, edit the ROM to creat a custom entry point, then build a CTR game card with that ROM, but this is quite expensive and needs a lots of hardware, software and knowledge.

You need to find an exploit in the game. Reverse the save checksum, otherwise any edit would make the save corrupt. Check for vulnerabilities, such as buffer overflow etc. Check if the vulnerability can be exploited, if yes you can load custom code with it. Create a payload, a rop and you're done. If that's out of your knowledge then you can't do it.
