Well, this has to do with compatibility, and about Sonic Rush (U), so I figured I should post it here. I figured out how to make it run partially... um, read on, you'll see. Someone tested and later I did, not knowing it had already been tested. According to the flash compat. program neither of us got it to work... however, now I've figured out a way to get to the menu's, very strangely, maybe it'll work for other games?
Okay, well, first you have to run a working rom, like Mr. Driller for example. (Not all might work) While it's at the intro doing it's thing with logos, click the 'open file' button folder thing. Choose Sonic Rush (U), and "just press play, you gotta do it anyway". Give it a couple seconds, and the bottom screen should blink a random color. It could be red, blue, white, or green from what I've seen. Anyway, knock in a combo of enter and z buttons, and you should make the color go to the top screen, keep doing it and the logos will start... Keep goin'

lain: ... Now you should give it a sec and it'll have the menu up. Just keep pressing enter and z till It gives you three options. All of them will make it crash unfortunately.
Now, if you ask me, it's strange that it works, and perhaps it can make other games that have black screens work as well. I only tested Lost Magic too, and it didn't work
The reason I post this is because I really want someone to try this also. Please. You never know if something like this could work, it did for Sonic Rush...
If you think I'm trying to make you waste 5 minutes of your life, I got some screens for proof:
The top left screen is the top screen of the first step into the menu. The bottom left screen is if you let the game sit on the main menu, it appears to go ino a cinematic, but then it just crashes. The screen on the right is the screen after you pick the first option at the main menu. My crappy paintbrush text explains the rest.
Please test this also, I might just have some king of weird defectiveness with my computer

lain:
Edit - My bad. Sorry for the double post.
PS - Incase you didn't get my point, this post wasn't all about getting Sonic Rush into the menu's, but rather
perhaps a method of getting other games that hang on black screens to work also.
PS2- Also, could someone try this with another version of Sonic Rush, like (E) or (J)? I can't get my hands on one at the moment.
