I would really like specific steps on what to do and what software I may have to download to do so.

hello!! trying to do the same thing as OP here, but I'm not finding a "usrcheats.dat" file anywhere. I have the "sd:/_nds/TWiLightMenu/extras/" no issue, but I'm super new at this.
- Where did you hear that the games are emulated, and not ran natively?
- Just find "usrcheat.dat", and put it in "sd:/_nds/TWiLightMenu/extras/". Then in the ROM menu, press Y, and then X, to open the cheat menu.

You download it from here: https://gbatemp.net/threads/deadskullzjrs-nds-i-cheat-databases.488711/hello!! trying to do the same thing as OP here, but I'm not finding a "usrcheats.dat" file anywhere. I have the "sd:/_nds/TWiLightMenu/extras/" no issue, but I'm super new at this.

Change the game ID in R4CCE to match your rom.yeah but the problem is ive tried to do that but theres no cheats that show up for Fire Emblem 12 (Fire Emblem - Heroes of Light and Shadow (Japan) (Rev 1) (NDSi Enhanced) [T-En by The Heroes of Shadow v3.01] [n].nds) and i cant find the right patch or rom or anything like that thats already *in* the cheat database, i have no idea what to do
