Title: Burned CD32 disc slow access
Post by: dougal on October 24, 2011, 11:53:49 AM
I burned a compilation (CD888) for the CD32.

The disc does work but the CD32 is accessing it very slowly. For example the main menu took about 2 minutes to load.

Then scrolling through the games list is slow.

I loaded State of the Art Demo and it kept pausing to access the cd.

Is there a special way of burning the discs?

I used disk utility on my Mac to burn it. I do have a PC with other software like imgburn etc.. but i didnt try yet not to waste blank cd's.

Try using good quality CDs. I use Verbatim myself for normal data, they may be good enough.

If not, though, I know from experience of burning karaoke CD+Gs though (which have to be VERY good quality) the best way of burning them was to use Audio CD-Rs (TDK) which are better quality again. I also burned them using my old, slow burner (a SCSI Yamaha CRW4260t I think) as they burn a better signal than the newer 48x and above burners.

Of course, your milage may vary, as with anything else, but that's what I found was best for me.

I used Emtec discs (BASF) so they are def a good brand i guess.

I burnt them at 8X using the superdrive of my iMac (aluminum model).

I have only had success when burning them at x2 speed and using top quality CD-R's

Another vote for burning at minimum speed.

Hi, I had the same problem year ago.
And I tried all, (burning at x2 speed, with differents cd burners and softs, etc)

But I solved the problem replacing the laser unit in the cd32.

Now my cd32 read the cds without probs, all cds / trademarks, not only original cds.

Here you have a tutorial:

Yes unfortunately pressed cd's and cd-r's are different, cd-rw's are different again. So unless the cd32 was designed with reading cd-r's then it's pot luck whether it will work, especially given the age as the laser units do deteriorate with age.
 
The game cube had a similar problem. Only a very few mini dvd-r's would work, it depended on what type of dye the discs used & also something in the console. Even weirder the discs I burnt at 1x & 2x were unreadable, only if they were burnt at 4x would they work.

Yes, other CD consoles have the same problem, but changing the laser unit, you can use all kind of cds and burn at all speeds.

I think I paid only 10-15 euros. I bought the Kss-210b model.

(sorry, I don't know how to scale a linked image)

The CD32 has a pretty weak laser. It was my introduction to the Amiga and I have experimented with them a lot. I have found that the "quality" of a CD doesn't seem to matter so much. It's the reflective surface of the CD that matters. Some of these high quality CD-Rs use a deep blue ink, which the CD32's weak laser just gets lost in. For best results, try to find some CD-Rs that have a shiny silver finish to them, preferably with a white "printable" label side surface, they're the most reflective and work best with the old CD32 laser. Also, make sure you burn them at the slowest speed, it seems to help too!

I'll have another go burning @ 1X. Originals seem to work fine.

You are very lucky if you can burn your iso's with only 1x, because new cd burners cant burn cd's at 1-4x in my experience. Every time I have tried to  burn old iso's at 1x, all my burners automatically selects a higher value. My laptop always burns at 10x(!) but the CD's work just fine on my cd32.

It could be that the state of the art demo just keeps loading data from "HD" while its playing, and as you may know, the screen blinks while the data is loaded from the cd if it's not preloaded by whdload.

I tested the "state of the art" demo and it blinks and pauses with me to, so its accessing WB to load data while it's playing.
BTW, CD-888 compilation is the slowest of the comp including the 444 comp. 100&200 -comps are much faster in loading times.

Yip. I always burn CDs and even DVDs at the slowest speed, critical when burning large movie files for example, you can end up with corrupt footage etc

what's the hurry anyway ;-)

Firstly, modern CDRs don't like being burn't at low speeds.  Secondly, I had best results after I replaced my old Toshiba 8424 SCSI drive with a cheap crappy IDE unit and burnt at maximum speed in MakeCD.
