Title: CD as format for Commodore 64
Post by: sharp on October 17, 2016, 02:30:30 PM
Can cd be added for Commodore 64 as format. I just bought https://www.c64-wiki.com/index.php/1st_CD-Edition_(Collection) on eBay.

Oh and it's cd not cd-rom due to the tracks are technically on a audio cd-format.

Audio CDs are still CD-ROMs? CD-ROM is just a CD format where you can't overwrite the data (Read Only). What you're referring to is just the write type for the disc.

This is an interesting question. Hadn't considered this before. Figureing Shadow was right I nearly moved on but ended up checking out wiki.

https://en.wikipedia.org/wiki/CD-ROM
https://en.wikipedia.org/wiki/Compact_Disc_Digital_Audio

First article explains why CR-ROM is different from regular audio CDs. If you don't want to bother reading :) my quick summary is: They are very similar in almost all ways except,
1. CD-ROM is an official named standard separate from most audio CD's which are Compact Disc Digital Audio (CDDA or CD-DA)
2. The sector structure is different. Or the way the memory is divided on the disc.
3. I don't know if there are others, it's too early in the morning to read much of this, haven't even finished my tea.....

Other than I'm not sure how you would tell the difference between the two, being as they are so similar, other than the logo for one or the other printed somewhere, it seems like this could easily cause confusion if a system had both formats as options.

If both options are wanted, I could see adding both for total accuracy. Possibly a warning could pop up when someone chose the CDDA option saying, "are you sure you don't want CD-ROM?" This would also open the door for all sorts of slight format changes, Google gives these as examples for just CDs: Compact Disc (CD): CD-DA, CD-ROM, CD-R, CD-RW, 5.1 Music Disc, Super Audio CD (SACD), Photo CD, CD Video (CDV), Video CD (VCD), Super Video CD (SVCD), CD+G, CD-Text, CD-ROM XA, CD-i.

I can see there only being one option, CD-ROM or whatever for most systems, (maybe IBM/PC can have all options?   :-\ ) This seems simpler and I would certainly understand it being this way. It can always be added in the Trivia section that any particular thing is a specific format.

Yes, but the question was because we have CD-ROM in the Media Formats already, which I can just tie to the C64. Do you want CD-ROM, or do you need CD or CDDA added?

Sometime in the future I'll be adding this compilation which is on CD so can we add CD-ROM as a media format.

I'll just add it as CD-ROM then. All I needed to know. Thanks.
EDIT: Done.
