Okay, so, as far as Dreamcast goes, I've tried Chankast, and no dice. I have DAEMON Tools Lite, latest version. I have not downloaded any other version because they're only free for 20 or so days.

Problem 1 - BIOS

I've downloaded the BIOS .zip from the site, but I don't know what half of the files are or where to put them. I assumed they just went in the ChanKast folder and put 'em in there. Had to rename DC - BIOS and DC - Flash to dc_bios and dc_flash. I don't know if it's working properly, but it did stop saying it couldn't read "dc_bios.bin". However, I still don't know what to do with DC - BIOS (All), DC - Flash (All), DC - VMS BIOS (full), DC - Utopia Loader V1.1 (Though from what I've read on here this one's a self-booting program), or DC - Utopia Loader V1.1.nrg, all of which were also in the BIOS package.

Problem 2 - Games in Pieces

I've downloaded only one game, so I'm not sure if they are all like this, but Resident Evil: CODE Veronica for the Dreamcast is in pieces once you extract it, leaving me lost and confused. I don't know if that's the reason I'm getting the audio CD screen or not, but it seems quite possible that it's the cause. That, or the disc is not set to self-boot, which brings us to...

Problem 3 - Self-Booting

How does this work? How do I tell if my disc image is set to self-boot? How do I make my disc-image self-bootable? Does my game HAVE to self-boot to play?

Problem 4 - No Startup Text?

So far I've gotten the startup to respond to gamepad inputs. However, I have no way to tell what I am doing, as there is no text where I am pretty sure there should be. How do I fix this? There's also the fact that left/right is up/down, and vice versa, though I may have simply input the controls incorrectly.
