IS there a way to test GC Isos?

    I'm facing the following problem: when i get a GC Iso (GCM), sometimes i burn the image and get DRE when reading the game. But, after using one of the GCM fix tools available, i burn the image and it works fine. I want to know if someone knows about a way or a app to test the GCM to see if it has chances to have DRE, so i could test the iso BEFORE burning it, and, if needed, i would use the gcm fix tool, and so i could save some dvds... some give me a simplist answer, saying that i could just use the gcm fix app in ALL my gcm before burning, but i think that's not a good idea, since there's a good chance for a good gcm to become a bad one after being "fixed" if not needed. sorry for my bad english, i know it sucks. i have some contacts in the gamecube scene, and no one knows such app (altough they liked the idea), but even so i'll give my last try asking in this forum. thanx in advance.

    You could try streaming the iso to the GC and playing it that way to see if it works or not.

    Well, i read on modthatcube page, that u can test the disc after burning it, i quote

    I known u want to do it before, but thas all that i got, i think that maybe, and repeat MAYBE, u can mount the iso on one virtual drive, and try to test it (i dont known if its even possible or if could damage your drive or hard disk by doing that, so you are at your own and what you do its at your risk) But im no trying to scare you. :)

    And sorry for my bad english, i do it better on spanish

    Hum... testing a iso mounted in a virtual device is not going to work, because the DRE i get are not related to bad media or bad burn, but to bad allocation of the data in disc. only a gamecube can be sure if the FST data allocation is right for him or not. so, streaming the iso or testing the disc (the test you described test the quality of the burned data, not related to data allocation in disc) is not going to work. GC need to have this FST offset allocated fairly or it is not going to read the game easily. lot of DRE people get are related to this "FST offset", but most people don't even know about this issue. so, in other words, i wanna if there is some way out there to test this fst offset, to know if it is right BEFORE burning the disc, and not taking the risk to record a game that will not be fully readable by the GC. Remember: Not all DRE are realted to media quality or laser power, ALMOST ALL DRE people get after adjust the laser pot and burning game in a good media are related to this FST offset. there are apps out there that are supposed to fix this FST offset, rewriting it inside the iso in the correct way to be readable by GC. But, there is a chance that this app will screw up your iso if you use it in a iso that is already writen in a fine FST offset allocation. I know that i could just do "try an error", but i wanna skip the part of burning useless discs and losing some pricey ridata mini dvd-r (i have chosen to use minis because i want to leave my GC as unmodded as possible, most original look as possible). but in the end, i believe that losing some discs doing test and error is the price i have to pay until all my isos are fully burn-tested. well, thanx to everyone for trying to help in this thread, and sorry for my bad english. if someone find something that could be useful to us, post it, please.

    oh, one more thing: even if i don't believe the test you sugested will work, i'll try it. i don't believe i'll damage my hard drive or wathever doing so, this is VERY unlike, if not impossible. if wors't the program will give me an error message or crash, or maybe a system crash. i'm pretty sure that no hardware will be damaged. and, in the hipothesys of a hardware damage, don't worry, i'm doing it on my own, and i'm not going to blame you, hahaha!!

    Really i dont know that, but everyday im a bit less noob.

    And what about streaming with BBA?

    Or maybe burning on mini DVD-RW, (if they even exists)

    when streaming, i can only test if the game is fine, there's no waqy to test the allocation of the data, since it doesn't matter when streaming the game. and about the mini dvd-rw, yes, they are available, and they could be a very nice aswer to my problem, but the GC drive is not made to read rewritable disc (wich are fisically different from normal recordable discs. RW has a very smaller laser reflection rate, the drive must be able to deal with small laser reflection coming from disc), so i will most likely start having media related DRE. bust is a good idea, think i'll give it a try.

    o_O

    The only reason I mentioned streaming is because some images are just bad rips, and will cause DREs regardless.

    Also, mounting a GC image isn't going to do any damage to your PC.
