Sonic CD [NPUB30624]

[ssshadow]

Nooooo, the options -> settings menu hangs with this error:

E {PPU[1] Thread (main_thread)[0x0001b048]} PPUInterpreter::STW(): invalid address (0x10000000b)

Not perfect yet

Edit: Other issues, loading (or maybe saving?) doesn't work, if you change which soundtrack to use it saves the new preference, but after a restart the change is not there. Same for game progress. Other submenus from options also hangs with the same error.
Opening achievements or leaderboards just straight up crashes rpcs3 with no errors in the log.

Does it save the actual changes in the settings on a real PS3?

It does. It also saves which level you have reached and all that. Currently nothing is actually saved (or loaded?) in rcps3.
