hi i am new to the world of cd32. I have just got one I have many originals. I have some collections on iso I am burning and wanna play them. I am using wikipedia instructions. I am writing at x16. The cds are not being read as fast as the originals. This means massive loading time and the cd sounds really horrible when spinning. I am using DATASAFE BLANK DISC CD-R 52X will a change in cd help or will it be the way i am burning. One back up that did work really loaded instantly and sounded nice. I dunno what my problem is any help would be ace. Thanks
-
16x is quite fast actually. Try burning slower and use a different brand of CD-R. In addition, some drives aren't good at reading CD-Rs at all (I don't know if the CD32 should be, though).
-
I've always found that if the cd constantly speeds up then slows down again coupled with the sound like the disc is trying to burst out of the top of the drive, then a simple adjustment to the burning speed of the cd is all that is required.
When in doubt burn cd's at 2x or 4x maximum :-)
-
The CD32 drive is a 2x drive so I would imagine 2x burning would produce the best results...
-
Hi thanks for advice guys. I was getting the horrible noise. Just gotta wait for more cds to arrive. I was wondering which program you can write 2x because the lowest on Nero (which I am using) is 4x. Which cds should I get what do you guys recomend any good cheap ones?
-
Easy_burning worked well for my needs under Win98. I preferred it to Nero, but I didn't need any "advanced" features.
Edit: Also, for disks, I use Datawrite 1x-52x 700MB CD-R. This was on recommendation from my local PC shop, their engineers used them and said they had had no problems. I have so far only produced 2 coasters (out of approx. 50 written), both of which were early on, and I can't prove that it was the disks rather than me {bleep}ing up that was the cause, so they seem ok.
-
The problem is that those old drives aren't good at reading... Try to burn as slow as you can. Probably use Verbatim for burning...they are expensive but good.

Hi,

Hi, for what it's worth, I burn discs for all my older CD-based systems at 8X or slower, have had no problems. I use TDK disks. Also, maybe my CD32 is wierd, but I have little luck getting to play CD-r's, only plays CD-R's for music....Odd

Firstly hello all, am new here :) had an amiga during the early 90's and decided the othe day to get her out again and see what happens.
I've been playin through some of my old CD32 games but also have got my hands on a few of the iso out there. As is mentioned above in the thread I too am having serious trouble buring anything and getting it to work. It appears that games of a few mb in size work fine but anything bigger always fails.
I've used Nero, Alcohol 120% and ImgBurn with exactly the same results in each. The majority of games just sit on the amiga cd32 screen and finally after 10minutes dump out into a workbench with some random error.
Could my problem be that my old machine is on its way out? Or is it just that she was built before the days of CD-R's and the drive don't like them with to much info on.
Any advice would be great. I can always just use WINUAE but would rather be using the real deal.
P.S. Sorry for the long post.
-
First I would make sure that you are using cdr and not cdrw. Second dont burn more than 4X if you can and definately no more than 8x. Try using ISO Burn to make the cd's. I have Beneath a Steel Sky on a generic CDR and it runs great, but using high quality discs might be better. Good Luck

@Thread
So, the speed that you use to write a cd affects its reading speed?? For example, if someone is restricted to write cd's at x4 due to slow IDE interface, these cd's can not be read at higher speeds on another computer?

On most occasions yes.

No, writing speed affects reading speed because the writing Laser has (if you burn at 4x instead of 16x) 4 times more time to mark a bit as set (marking it more clearly) thus it is easier to read. -> Write a note up in a hurry and give it to someone to read. Write another note of similar length but take time writing it down, and give it the same person to read. Guess which note will he have "deciphered" faster.
-
I see. Thanks for the explanation, Donar.
-
Just out of interest is it possible to 'swap' the drive for a more modern drive so that the cd32 is capable of reading better.
Oh and I'm still not having any luck. Have tried more ISO burning tools am burning at 4x using Verbatim CD-R's.
-
Unfortunately the CD32 has a proprietary CD-Drive. Nobody found a 3rd party replacement up to now.
4x times and Verbatim CD-R sounds good. Do your Backups work in WinUAE?
Do you have a friend that could do a backup for you? Maybe your burner is faulty, writes the first MB ok and then craps out.
Can you try your backups in another CD32, maybe the drive is worn out and you have to geat a replacement, don't fear they are around...maybe try cleaning the lens but watch out not to break it.
-
Sounds like a bad burner to me. My DVD combo drive used to burn a cd good, then it would complete say an mix of songs and only the first four were playable, this started happening even though Nero said it was completed. Now the drive craps out after about 3%, so maybe try a new burner (they're cheap anyways now). Also are your ISO's good? where did you acquire them? Can someone else burn the same ISO from another computer ect... If i remember right I had heard of someone replacing the CDROM with another one a 4X speed one, but I'd have to hunt back into my saved stuff to find the article and what drive it was (a NEC I believe). Heck I never tried so not sure it would work either
-
Just a warn: never open/edit the .ISO on the peecee!
Doing this and you'll get all files with special bits on the CD not correctly setted.
Explaining better: there is special flags on Amiga's archives and files, not existing in some other systems (like M$ Windoz). Some of those flags are essencial to keep some programs running (others don't).
-
Cheers for the further advice guys. Have tried the ISOs in UAE and they are working fine. Also decided to try my original copy of cannon fodder which the CD32 won't read and it works on the PC so am starting to think its my old console. Shame really as I was in the mood for some old skool gaming. I think it will be easier to get another machine off ebay rather than try and hack this one apart.

I don't think that a "new" one from ebay has to be much better than yours... why not try to get a new laser? Vesalia in germany should have some maybe AmiKit too... but before you buy a new one:
Try to clean the lens with some alcohol or window cleaner and a piece of cloth that is made for doing this kind of stuff.
-
FIXED IT
Decided to open the cd32 and have a look. On the CD Drives board (under the metal cover) there are 4 little blue chaps that you can adjust. Since i thought my drive was knackered I gave them a little tweek firstly right after which nothing at all worked then left after which everything works. Don't asked what they are, how they worked or if it will work for you as I don't really have a clue. Perhaps someone could shed some light but is safe to say she now reads the cd-r's as if they were originals.
-
Hey congratulations, have fun with your CD32.
Maybe you increased laser voltage? Helps on "old" Playstation II's also. Playstation drives are crap...
-
It's a known trick on Sega Saturns too. I had to do it to mine. Changing the potentiometers increases the laser strength, which a) shortens the life of the laser (but hey, if it's not working anyway what've you got to lose!?) and b) sends a higher intensity laser beam which reflects better because it's stronger, so the receptor picks up the data better.
Eventually, though, all the lasers will be put up to max power and still not work, then it's new-laser-time.....
Edit: Incidentally, I've not tried this but in theory this should allow the drive to read CD-RWs too, if you up the voltage enough....
-
Disclaimer: Cranking up the voltage can fry your laser, so if it's working better don't try it.
Forgot to mention this when i replied first...
-
Hi,I agree with Donar.
But a Laser pickup replacement part is around 17 Euros for a CD32 ... (Sony KSS-212A but why it's not mentionned in the FAQ ????)
-
I think i'll leave mine as it is now. I had already ordered a new drive for the cd32 so if the laser goes i'll just swap out. But as the other have said if this is increasing the voltage then i would recommend only touching it as a last resort i.e. when the drive doesn't work anyway.
