Problem with burned cd games.

I bought turbo duo week ago.There is interesting issue about some burned cd games: there is no sound effects(like kicks or bangs) in Double Dragon 2 and Riot Zone, games run well, and cd soundtrack too, but in Castlevania or Golden Axe everything is normal.I used three different cd-r's (tdk,verbatim,pleomax), on two different cd burners which support 4x for cd's.Question is where is problem:in images, cdrs, console, burning software or somewhere else?Or burning speed must be lower then 4x?Have someone same problem on their consoles?

 

Problem solvedI checked voltage on original nec dc adapter and it was 16.4 v, changed it for normal 10v adapter and now everything is ok.If you are buyin something 20 years old from japan always check voltage first

 

16.4v would be normal as its unregulated. Under load the voltage would be at the value you expect.

 

6.4 v difference?But problem gone, what else can be?

 

its only 6.4v difference because you measured it with no load. This is normal for an unregulated PSU

 

I generally wouldn't recommend of using cdrs on any pce cd systems.
just shortens its rest life drastically.

 

thats not hole heartedly tru about the cd-r's wearing out your lasers if you use quality taiyo yundens, like their silver or gold masters burned at like 4x, will put no stress on the laser because the reflective surface is of such high quality instead of that cheap aluminum layer in bargain cd's, even verbatims suck from time to time anymore, i only trust yunden

 

Do CD-R's really work the laser that much harder? Does the CD-ROM have trouble focusing on the track or something which causes it to burn out faster?

 

It really depends on the quality of the CD-R. Obviously better quality CD-Rs like those made by Taiyo Yuden (which are what I use now) will perform about the same, if not exactly the same, as original pressed discs. Lower quality ones and especially CD-RWs and colored CD-Rs put more stress on the laser and hence cause it to wear out faster than normal.

 

Using your system will cause it to wear out. Please refrain from using your system. Just sit and look at it, maybe close your eyes and imagine yourself playing it.

Seriously though, you can play CD-Rs on your PC-Engine just fine usually. But you shouldn't go using cheap crap CD-Rs. Some setups may particularly not care for CD-Rs. I used to own a PC-Engine DUO (the black original one) which on certain CDs would tend to have the sled get stuck around the outside edge. I eventually sold that system but later bought my current DUO-R system which has not had any issues with CD-Rs.

I don't really think that you're in any danger of causing additional wear on your system by using a CD-R unless maybe if the CD-R is very poor quality. With that said, it's very enjoyable to own original CD-ROM games. But some of them are just far to pricey for most people.

 

I'd like to see some sort of quantitative study of this sort of thing but chances are it'll never happen.

 

Without new systems to test with, is this even possible?

 

It is an undeniable fact that the laser and mechatronics gets worn out faster by the use of CD-Rs compared to original pressed CDs.
Within the PCE community many cases so far were reported referable to the use/absue of CD-Rs.

I even witnessed one case of my friends DUO (black japanese) which instantly died on its first run of a CD-R ever, which worked flawless until that incident.
i will not say that the DUO was probably in super health and the CD-R just swallowed its whole life meter in one hit. so the DUO sure must already be weakened due to the normal use over the many years, but seeing that one single CD-R gave it le instant coup de grâce, tells me more than everything else.

So NO, unless you're not using very high quality CD-Rs burned on the lowest speed just possible (best would be single speed of course), you, resp. your system won't be save if using CD-Rs. and even then i have my doubts that it won't hurt it at all.

 

The original Duo's are fussy about CD-Rs. I have 3 different Duo's give me the 'parked' laser issue when using really cheap CD-Rs. That's when the laser module gets stuck all the way on the right side and can't return back. You have to manually spin the shaft in order to get it unstuck. It's mostly likely what happened to Tats' friends system.

My SuperCDROM^2 plays anything that I throw at it. Even ~really~ crap CD-Rs. Never had a problem. Been playing CD-Rs on it for years now. I've heard that the Duo-R/RX models are the same as the SuperCDROM^2 models; they handle CD-Rs quite well.

The TGCD and original brief case model PCECD units, are finicky with CD-Rs. While I haven't seen them die, I have seen them have a hard time with a lot of CD-Rs.

Then there are issues with some burning apps not burning the data track in the correct mode (which is insane!). Even though the CUE sheet specifically stated mode1/2048 (cooked) format, the app burned it as Mode2 form (I forget which form). The Duo unit actually read this! But it really choked on reading these. IIRC, some version of Nero did this. Though it burned the image fine, if the source was a bin/cue. Stupid burning apps. Can't trust 'em. It's always important to verify your setup (burn a PCE CD at least once and analyze the disc to make sure the burner/software setup is burning correctly per the CUE sheet).

 

I've used both questionable quality Memorex CD-Rs and excellent Taiyo Yuden CD-Rs on my Duo-R and it has yet to show any sign of weakness. I used to own an original PCE Duo years back and that never had a single issue with CD-Rs either. I even had a TG-CD setup at one point and it had no problems with CD-Rs.

 

I'm currently having a problem with CDRs on my Japanese Duo. Regular games play perfectly but CDrs either won't load, or when they do I often have the audio track cutting out after a few seconds to a minute. Might need to do some more pot adjustment I guess.

 

How are you burning your games?

 

I use IMGburn and either BIN/CUEs or CUE/ISO/WAVs for translated games. They play pretty much perfect on my friend's DUO-R with no loss in Audio or music dropping off. On mine however, sometimes they won't load, other times they load, but the music cuts out after a minute or many times even less. I'm thinking of grabbing some 74 Minute MAM-As as I know those are high quality, but after seeing the games work perfectly on my buddy's system I don't think it's the burn or the media.
