Same error...
You said you use 2 games header, right ?
Ridge Racer 3D has no online. What's your other game ?
Pokémon sapphire alpha
Mk7 working great online for me (burner 2ds). Though I'm getting 002-0123 on street fighter 4. Wonder what's at play here.
Which is a CARD2 Game (NAND saving). Now I understand.
You'll have to find another private header.
Don't know if it'll fix but SFIV PAL and NTSC have different chipset info in template.
Assuming you're playing USA Rom, search CTR-P-ASSE.
Under SHA1, change 45 F8 00 90 with C2 F8 00 90
May want to update the original post to reflect the changes you've made. More Sky3ds users need to know about this tool.
I've been using a Nintendogs header for mine. No issues thus far. Of course you realize there are no guarantees. Private headers themselves may not be safe. Nobody knows for a fact.
Can you please add an option for using multiple header for the whole template file?
Like Game 1 -> Header 1
Game 2 -> Header 2
Game 3 -> Header 3
Game 4 -> Header 4
Game 5 -> Header 1
...
(For much header like in my case, 4 ^^)
