DreamShell 4.0 Beta 4

[SWAT]

You are using the dreamshell_boot_loader.bios to run the games?
Well, then everything is clear, with this BIOS the games does not work.
To normal start the games, you need to use the dreamshell_loader_with.bios (or in best case original bios), this bios having all needed syscalls and params, including the DC ID.
But you need (for dreamshell_loader_with.bios) to boot from ip.bin and high memory loader (select this params in iso laoder).

P.S. To show console in DS GUI (if you not have keyboard), press START button on joystick and then press A button. If you have keyboard, just press Esc.
