I can also reproduce this error on macOS Monterey using brew as my services manager.

I'll have to check again later today, but it may have something to do with the size of my SD card? (2GB)

It could be that it is a Micro SD card, in a converter plugged into my SD slot, I don't know why that would be, but it is possible? Don't...

It does get past that, just FYI, I am on Windows, I don't know if that effects anything...

It looks like it works, until after the CTR Transfer step, when it says 404 not found

I don't know if that's supposted to happen or not...

Okay, I got more information. It turns out that games only launch when I use XCode to attach to the process... and then the games won't show a title screen....

Not jailbroken, but I will have to try Mario Party 5 and get back to you.

Would jailbreaking do anything bad to my device? It's my main phone and last time I jailbroke an old ipod it didn't work out too well. :/

Mario Party 5 results in the same thing as the rest of the games, just FYI.
