I'm still trying to run Sonic Rush to ot much success. As it happened, the problem before was that I had my card formatted to 8 Kb cluster size. Now it's 64 Kb, and loading times sure shortened greatly. I also can enter Spcial Stage(attempted on 1st level), as well as leave it successfully after taking Chaos Emerald. I can also get through first cutscene, but it white screens instead of boss battle which should follow. All this with Sonic Chronicles cartridge inserted. ...oh, and it also seem to give me white screen instead of cutscene after I've got Chaos Emerald. That's weird. First attempt (without Choas Emerald) was done on 0.1.0, after cutscene I was unable to proceed to boss fight due to white screen. Second attempt I decided to try and roll back to card2 release and on it I was able to get through Special Stage, but instead of pre-boss cutscene I get white screen.
