I was wondering when is it necessary to re-build an ISO image for a PS2 DVD-5 Game. I will beat you all to it and say that I have tried to search. All the threads I have found mention if the ISO file is greater than 4.36 Gb, then it will need rebuilding. Many of the threads have implied that you only need to do that if you use Swap Magic or a swap method. Do you need to rebuild if you are using a chip (specifically: Matrix Infinity Green Dot)? I am trying to backup my Star Wars: Battlefront and Star Wars: Battlefront 2.
Also, if someone could give a quick explination to why a rebuild is necessary that would also help. 4.36<4.7 Gb unless the ISO is slightly compressed.
There is lots of info on "how", but not enough info on "why" or "when".
Thanks in advance.

if you have the chip,doesnt need to be rebuild.
why or when,for swap magic disc user because of the swap magic toc,if the game bigger than the swap magic toc then it need to be rebuild,some is for playing off hdd(want to keep more games on hdd,then they rebuild iso),cuz some game have fake toc.

help. 4.36<4.7 Gb
Why is the disc capacity of a 4.7 GB DVD shown as 4.3 GB?
Answer Answer
You cannot record 4.7 GB of data on a 4.7 GB DVD.
The capacity of a 4.7 GB DVD is actually calculated in units of 1,000 bytes.
1 GB = 1,000 MB = 1,000,000 KB = 1,000,000,000 bytes
A computer calculates capacity in units of 1,024 bytes, so a 4.7 GB disc has a capacity of 4.3 to 4.4 GB on a computer.

huh? I did say "quick" explination, but..... huh?
J/K, I sort of get what you meant. So if 4.36Gb won't fit a DVD-R=4.7Gb, then why would it make a difference if it is swap magic or a mod chip? I guess I am confused on what the difference is.

the simple answer is a mod chio is much better than Swap Magic in many ways. Not having to rebuild games is just one of them.
That is just for people who use Swap Magic as it has problems playing some games because they have dummy/garbage files that need to be replaced, and then the ISO needs to be rebuilt. Otherwise Swap Magic will not play them.
A mod chip doesn't have that flaw. Plus if you have a good one that will play DVD9 Back ups (DMS4 or Matrix Infinity) you will not need to rebuild a DVD9 game to fit on a DVD5 disc, as the mod chip will play it. Swap Magic will not.

I have a Messiah Mod chip, and I've recently had troubles playing the Godfather.
It has the slow loading times that others have also complained about. The original ISO was about 3.62GB (from memory), and now that I've rebuilt it, the new ISO is 2.66GB, so there was a fair bit of dummy files.
Now, the game doesn't have the slow loading times problem anymore.
Same discs, same burning method, modchip not swap magic, and not a very large original ISO (i.e not 4.36GB). So why would this have happened???? because people are saying rebuilds are only needed for Swap Magic users and for very large ISOs.

So what I am hearing is that it is not necessary if you have a good mod chip, but it may or may not help game play (loading times). The ISO will fit on a DVD if the bytes (in file>properties for both) are low enough.
The type of the mod chip is also critical. Sounds like the Messiah chip may have trouble playing dummy files, maybe the Matrix Infinity won't?
So God of War can be compressed from a DVD-9 to a DVD-5 without rebuilding? I don't quite understand how that works.
I guess I will have to burn some coasters to fully understand this, but please keep the info coming. This is really helping. Thanks.

Yes, a GOOD mod chip like the two i mentioned should have no problems with dummy files. I know my DMS4 Pro hasn't.
If you have slow loading times then rebuilding it can help in SOME cases.
God Of War can be shrunk from DVD9 to DVD5, but with the 2 chips i mentioned you do not have to, just buy a DVD9 disc and copy it with DVD Decrypter and they will play your DVD9 back up just fine.
With Swap Magic you will have to shrink it taking out some bonus material. that is how it is done by taking out material they see as not critical to enjoying the game like bonus movies and the credits and such.
95% of the games around will fit on a normal DVD5 (4.7GB) just fine.
If you read around the forums and ask for some tutorials when you get your system modded and are ready to start then you should not need o make coasters and waste money to get it right. The people here can direct you to guides that will really help like the stickies at the top of these threads.

hello,
the swapmagic disk has a TOC of approx 4.36 gb i believe.
the swapmagic disk is basically made up of an old ps2 game that has been re-pressed,(onto crazy taxi)
when you want to boot a game with swapmagic disk's,you load the disk in,the ps2 then thinks an original game is being loaded
then you load a copied game in
if this copied game is the same size or above the TOC of the swapmagic disk,the ps2 thinks,hey,whats going on here?,thus it wont load.as the ps2 sees an image that is bigger than what it should be
you can either rebuild the iso if possible or do a TOC refresh
a TOC refresh is where you load swapmagic,then load in an original game that has a HIGH TOC,then load in the copied game
you do not need to rebuild any game if you have a modchip fitted
those that do and state it made the game load better should use better media or clean the laser head,as it is obvious the laser is not liking the fact that it has to scan the whole disk,maybe the laser is "tired"
you do not "play" dummy files,modchips do not play dummy files
dummy files are placed in the image to fill the disk out,and actually make the game run smoother,they are not put there by game developers to make the image bigger so they wont load using swapmagic disk
they do not contain any data
hopes this helps!!!
cheers and cheerio!!!

Crystal Clear understanding now. I had a lot of trouble finding this information bu searching. I wish your replies could be sticky'd for others.
I am really glad I listened to you guys and got the Matrix. Convenience and reliability go a long way in my books. I installed it (this weekend) and it works like a charm. I expected a challenge, but I had no idea that installation was as fine detail as it actually was. :D
Thanks again.

I found that the ISO I used for the Godfather before I rebuilt it did work, but the cut scenes were terrible, and sometimes even the gameplay was bad. i.e driving along quickly meant that the game couldn't load the surroundings quick enough, so you'd run off the edge of the scenery and have to wait ages before you could see what was happening.
When rebuilt, this no longer happened....so yeah....the game did work without a rebuild....but it was terrible, and pretty much unplayable.
With the rebuild, the same media was used as before, and it works fine.
So I guess a Messiah is just not as good as DMS4 or Matrix Infinity, so that'd be why I needed to rebuild but other people didn't.
Sorry, but I didn't mean to say 'dummy files' in my previous post, I meant to say the useless data that is eliminated after a rebuild.
My next question is continuing on the WHY aspect of rebuilding. I rebuilt Manhunt, and it lost over a GB of useless data or whatever you call it, but it wouldn't work on my PS2. I then just burnt the original ISO (non-rebuilt one) and it works fine.
Why then does a rebuild work sometimes, but not others? Where, as with the Godfather, a rebuild for my Messiah Chip was pretty much necessary, but with Manhunt, the un-rebuilt version works, but the rebuilt one doesn't.

hello sainter54,
i am not about to start arguing here about when/why should i/shouldnt i rebuild,as it worked for you in godfather,which is good
but that is not down to you using a messiah modchip i can promise you that.
the messiah chip is an old chip,but a very good one,and i am assuming your ps2 is fairly old?,like i explained before,i bet if you cleaned the laser head,and used good disk's it would load properly without a rebuild
what disk's do you use btw?
cheers!!

Nah, it's not the laser or anything else on the ps2 coz I took it into a shop and they tried it on other ps2s, including a new slimline one and the game had the same effect....poor loading and bad gameplay.
not sure what chips the other ps2s had in them.
I'm using TDK-Rs, burning at slowest speed using DVD Decrypter. Maybe it's just an inconsistent problem.....some people have it, others don't.....
hehehe.....theres my theory to something I don't understand.....Nothing!

as the chip is not at fault here
hope this helps

I also suggest getting some better media, TDK is ok.
I did use a few in the past when i first started out backing up my games and had no real problems. But there are just so many factors that can effect the gameplay on a backup it is more like a process of elimination than a solution to your problem. I can tell you that i use DVD's that most media guides do not rate to highly. But after 2 years and no problems i would have to disagree with those guide on this point. I could use better media, but i get these cheap and they work every time for my PS2 games, Xbox games, and movies
I use Philips 8X DVD-R
here are just a few of the things that could cause your problems.
1. outdated firmware on your burner
2. burning an 8X DVD at 1X instead of 4X
3. running programs in the backround of the PC or using the PC when burning
3. quality of the dye used on your media
4. +R and -R, some PS2's read a certain type better than others, mine hates DVD+R
i would look into all that if you have not already. I have never had to rebuild a game since getting my chip. If you REALLY want to increase your load times and get better performance then get a DMS4 Pro chip and install a hard drive (if you have a chuncky style PS2)

hmmmm....I thought the discs might've been the problem, but then the rebuilt version worked perfectly on the TDKs, so that got me thinking it wasn't the disc.
The TDK-Rs say they are 1-8x speed, and I always burn at the lowest possible speed, and my Playstation prefers the -Rs. Should I be burning at 4x if 1x is still an option? because a guy at my Playstation repairs shop told me to burn at the slowest possible speed.
How do I check/update the firmware for my burner, and what effect might that have if it's out of date?

Your right, sort of,
Sainter54 could booktype but only if the drive supports booktyping and..... instead of the DVD-R's, DVD+R would have to be used.
That means the problem might go away, but the cause will be unclear as to whether the media or booktyping solved it.
I suggest trying some verbatims first, and the suggestion of cleaning the laser would be good maintenace anyway whether it works or not for this problem.
Good luck with your modded PS2 Kellyk75

Thanks, loving it so far. No probs and plays like origonals..... easy as pie.
As for the booktyping, I guess that is just for DVD+R's? Glad you mentioned that. I'm still in the newb learning curve.....
:D

Yes, you can only booktype DVD+R and only if your burner can do it.
That is why i pretty much stick to the 8X DVD-R as i have never
had a problem with those.
