Nope because it needs kernel to work. Which is in way older custom firmware and the only way to use it for newer cfw is through eloader.

I don't know, try to sign the eboot or just try with other CFW [Pro-B10 or ME].... but the game reach the full speed is posible?? because the game it's not official for PSP

Have the game goes great and all, but sometimes the game goes slow.

And I don't get it. In the latest version of SMW (1.7v2) there's two files one that it's called SMW and another that is called smw%. When putting smw file only the game works in the eloader, but in the xmb it says corrupted file.
The other file contains a Eboot file, I replace the other Eboot file (from smw) with the one on the smw%. In the xmb the game picture is working, but when loading with eloader it doesn't seems to work.

And the game is it dead for the PSP or do they still upgrade the game on the PSP. Pretty please make that game it's the best psp homebrew.
You can find the game in the forum discusion of this game. Google it.
