I tried playing a cd-r on my turbografx-cd, and it plays, but the loading takes a long, long, long time. We're talking several minutes to change maps. I know the thing is 1X, but that can't be normal. Did I improperly burn the disc, or is that to be expected? I know the proper procedure to burn the disc, and I followed it closely, (ME recognizes it with no error! message, TOCs verified, etc.) but it just spins the disc forever before something comes on screen. Is the hardware failing? I have been in these threads for awhile, but I'm new at this particular thing.

You can do a hardware mod to increase the laser intensity, that will likely fix the issue. The laser isn't really designed for reading the patterns of a CDR.

Is this what others have done? Also, is this difficult to do without damaging the unit? If not, how do I do it?

Try using higher quality media (TDK and Verbatim worked wonders for me)
and re-burn at the slowest possible speed.

Thanks Specineff. I will try that. I would still like to know how to do that laser mod if this doesn't work tho.

I'm not sure about the laser mod (I know about adjusting the laser strength in the dreamcast thtough) - unless you're refering to the replcement laser module that's been discussed on pcenginefx forums.

Update (actually more of a bump): I have thoroughly cleaned the laser lens with isopropyl alcohol and an equate q-tip. I reburned a copy of Ys III on a Verbatim CD-R. I used CDRWin (unregistered version), burned at 1X, no errors ocurred. This seems to have done approximately jack squizzat. From what I understand, the TG-CD usually works with cd-rs with no problems. Is that the case, or is it necessary to do something (like the laser mod mentioned above), or is this a hardware problem? I know at least half you guys have the system (all if you include the duo), come on man! Words of wisdom?

Well, here's some info about burning CD-Rs. Most new burners don't burn below 8x, but the ones that due tend to heat up the CD-R at such a slow rate burn. My plexter DVDR/CDR drive can burn at 6x, but the DUO/SCD has a hard time reading them, so I burn them at 8x.

CD-R type has a lot to due with it too. The deep blue color CD-Rs seem to work best while the light-to-silver CD-Rs (usually Sony or Memorex) don't work as well. The Verbatem "record top" CD-Rs have worked the best in my tests.

I have noticed that as the DUO laser module worsens, it has a harder time reading any CD-Rs (from the 3 Duo's I've tested) even though it will read pressed CD's just fine. If want to run CD-R's, I'd get a replacement laser module or PCE+CDROM2/PCE+SuperCDROM2. The replacement laser module is much cheaper, but it requires opening the Duo unit and disassembling it.

Sorry that I couldn't be of more help,
Rich

Thanks Tom. I have the TG-16 + CD, so should work better than the duo, right? I did some reading up on cd-rs and apparently the ones with azo (deep blue) dye are supposed to work the best like you mentioned. From what I have gotten from others, verbatim is the best brand, so I went with it. The cd-rs I got did not look blue, so does that really make a difference in most cases, or does it matter as long as its a quality brand?

I checked my hardware, the slowest speed available on my cd burner is 4x, its 8x on my DVD DL burner (tho cdrwin won't recognize that one as a recording drive!?). Everyone has said burn at slowest speed possible, but you are suggesting to try 8X+? I guess I will try almost anything at this point.

Does your TG-CD play original discs (i.e. not copies)? If it can't read a commertial disc then the problem is most likey with the TD-CD otherwise the problem is with the CD-R's or the burning process.

Well, since I just bought the cd add-on, I don't have any real cds yet. But even if I did, I wouldnt use them, I would only play backups. I have tried commercial music cds, which it plays with no problems. It just has problems with cd-rs. What I don't know is, why? I have heard the TG-CD reads cd-rs fine, better than the duo, in fact, and since duos do read them, why doesn't my TG-CD? I already know it is with the hardware or with the burning process, but which?

I'm starting to think it's the hardware. I used to have problems with CDR's, IIRC, CDRwin with the correct settings, Verbatim, & cleaning my lens solved all that. But it sounds like you've done all that. And regular cd's work fine you say? Hmmmm.

Have you tried a cd lens cleaner? One of those discs, with brushes on them, & a fluid that you put on the brush? That's what really worked for me cleaning my lens.
