Hey there. Title. To set the stage a bit, I do have CFW installed on my 3DS already, and do know how to dump, decrypt, and/or mount files with godmode9. This is so I can legally emulate my legally dumped DSiWare games.
DSiWare games played on NO$GBA emulator don't have working save states and saves.
Also, the BIOS for the Nintendo DSi, biosnds7.rom (16 KB - 1280F0D5) and biosnds9.rom (4 KB - 2AB23573), do not exist in the 3DS system titles:
0004013800000102 - Old_3DS TWL_FIRM
0004013820000102 - New_3DS TWL_FIRM
You can try extracting the .FIRM payload in both encrypted and decrypted versions from the 3DS system's DS(i) firmware, but you will not find them in there not even when hex searching.
Once again I fell down the martial arts rabbit hole and am plumbing the murky depths of the internet's various martial arts and fighting crafts echo chambers.
If you're not actively involved and only get up to speed every few years or so, you can see the tide of public opinion flapping worse than my dong while I'm skipping naked down a hallway.
