I've got the rom Gundam: Renpou vs Zeon DX (J) from somewhere, made it bootable, mounted the bootable image on daemon tools 3.29, got the DC BIOS, configured the control and drive settings of chankast, and got it finally running. However at the loading startup screen, i got this:
I know it asks to press the start button, and of course I did (I've checked the button works on the dreamcast logo screen), but the whole thing just freezes and stay like that. I've tried chankast v0.2a and 0.25 but it all have the same results. Any help to make it working will be appreciated
If you'll need any other info please do tell me. Many thanks.
