Homebrew - CFW Folder Blocker v1.0 - Image 1Homebrew developer Torch has released CFW Folder Blocker v1.0, a useful little plugin that hides CFW folders while in game mode.

Torch made the program to protect against new UMDs that detect and delete certain files, messing up your custom firmware.

Here are the release notes:

Some new UMDs are detecting files in the ms0:/seplugins and ms0:/iso folders and causing problems, even deleting files from these folders.


This plugin will hide these folders in GAME mode so they can't be accessed.


To install, copy cfwblock.prx to ms0:/seplugins and make an entry in game.txt e.g. ms0:/seplugins/cfwblock.txt 1


Download: CFW Folder Blocker v1.0
Visit: QJ.NET PSP Development Forums

*UPDATE* Torch warns that you should disable to this plugin if you want to use DAX's LEDA app. Says Torch:

EDIT: Before anyone asks, this will NOT bypass any anti-ISO protection in games. It is for the protection of YOUR files on YOUR memory stick. Use the original UMD and it will work fine, and your files are also safe.


Note: If you want to install DAX's LEDA then disable this temporarily to install it or it will show error. In the next version I will add a check to disable it in homebrew.

What the hell is Sony's freakin problem?
I can see why there tryin to stop the piracy, but deleting our own files? (the non-pirated ones?)
that's just kiddish. Sony's acting like kids...

stupid sony.

it was fair enough for them to patch thier firmware and hardware to stop us hacking... but deleting our files? now thats just low

They are deleting only pirated iso's. You wont have a problem if your not a pirate.

   Re: skoomaeater - 2009-02-04
 » Pirate vs Legal

And can you explain to me how Sony is going to know if the ISO's you are using are pirated or legal?

I personally hate UMD's, they are too loud, take up too much battery power, and are way too slow. There has to be a better solution to the piracy issue.

On top of that, seplugins isn't piracy, its preference. Why would they mess with that? Somehow I think that ninja-deleting files from our memorysticks is crossing the line into some legal issues. It is my mspd not theirs, I should get to choose what files get deleted.

   Re: kupomogli - 2009-02-04
 » skoomaeater

Anything that isn't UMD or PSN is considered pirated on the PSP.

You shouldn't be able to rip a PSP game to begin with. That in itself is illegal nowdays, as like on all DVDs, there are warnings that they cannot be reproduced in any way or form, not even for a simple backup copy. But everyone still does it.

So Sony deleting any of your ISO's is nothing wrong on their part. Stop being such a *****.

   Re: skoomaeater - 2009-02-04
 » kupomogli

First of all, Backups of UMD's or DVD's is NOT illegal everywhere, so before you open your mouth, stop to think about it. Secondly, not every ISO on a memorystick is a UMD ISO, did you ever stop to think about this?
Unless these UMD's are actually scanning the ISO to ensure it is UMD ISO, they shouldn't be allowed to do this. They really shouldn't be able to do it anyways. Sony can not delete my files without my permission and I think torch for this plugin to prevent it. Next time you open your mouth kupomogli I'll do you a favor and stick your foot in it for you so you won't have to do it yourself.

actually, Justin, your wrong. there's really no difference between pirated ISOs and our dumped ISOs. it will delete any iso. Learn before you talk.


   Re: kupomogli - 2009-02-04
 » NDWolfwood

Dumping any ISO's in itself is pirating. Making backup copies has been common practice for the longest time to that everyone does it, but it's still illegal.

Learn before you talk.

wouldnt unauthorised deletion of files come under the TROJAN catagory, whatever the system???
yes it may say in the licence agreement that sony have the right to delete files off their product, and that we "licence" the product for use from sony. but the way i see it...once its in my hands i can do whatever i want (even if its taking a sledgehammer 2 it ¬.¬).
Anyway this plugin was a very good idea for those who still use UMDs to play games


   Re: mattc41 - 2009-02-05
 » yes,

But you have to think of the logic, yes, unathorized deletion of file WOULD be considered a trojan, it is a preventitive measure agenst piracy. I mean, who is gonna go to sony and say, "Hey, you cant delete my iso, even if i pirated it and uploaded it to the internet.", yes some people actualy baught the game and use the iso as slower loading times, better portability, ect, but for the few others who decide to pirate, they ruin it for us all, because if there was no pirates, we could use our psp's legitamety without the sony vs. cfw/piracy debate, and i hope freeplay is reading this, as the comment he made above is a sort of, low blow.

Fine, I'll stop buying their UMDs altogether.

   by Qowface - 2009-02-04
 » O.o

So now Sony is deleting people's files using UMD's? That's pretty crazy...

The way I see it, they can't prove if the ISOs are illegal or not, since there's nothing illegal about making backups for personal use...if you own the UMD, it is legal to own an ISO of it as well...however, since a PSP with OFW can't use ISO files anyways, having them on there kind of proves you hacked your PSP, so I can see why Sony would remove them, even if it isn't right for them to do so...they're gonna stretch the end user agreement as far as possible, aren't they? -.-

I don't agree with the idea or think that Sony should delete files from your memory stick, but I see where they're coming from here...

P.S. Wouldn't it be obvious if the UMD was deleting a 1GB+ ISO from your memory stick? That doesn't happen instantly, it takes a little time...


   Re: Fade3e - 2009-02-05
 » not quite

deleting a file is different from creating or copying where the information the file holds is actually altered, but moving and deleting are diferent because ussually all they do is change the table of contents so to speak, so in deleting a file they could simply unlink the data from its area in the "Table of contents" which would take a sec, this doesnt actually delete the file as the data is still there just waiting to be overwritten, they could however go for a full delete and wipe the data too which would cause the noticability you mentioned

   Re: undeadrule1 - 2009-02-05
 » they probably do this

Well they probably do something similar to a "Quick Format" for computers. all it does is delete a little bit and register the file as empty space so when you write another file it just dumps the old iso

   Re: blade2577 - 2009-02-17
 » Hoax?

I haven't researched but I don't believe there's such thing as deleting a file. First it's not even "Sony"s fault since all they do is firmware. If it's when in game mode then that means the GAME is the one that's deleting the files... Not to mention I've never experienced such thing. And if it was an act to stop piracy I think it's the most ridiculous idea yet. Also ISOs as of a while ago have been illegal even if you own the original copy... this of course was made to "discourage" piracy.

As for my personal opinion if you're a pirate or if you're using a backup in makes no difference that Sony should not meddle with piracy since Sony and game companies don't have a real strong connection in sales in fact if more people buy a PSP to pirate Sony would sell more, even if the game companies don't. The only bad side to that is that game companies will be discouraged to make games but if we get a better commnuity homebrew can replace games.

They weren't making money because the vast majority of PSP titles are worthless, unoriginal or ported titles that nobody cares about. even when I loved the PSP I could only name 7 MUST HAVE titles.

Tip to sony+

Let the next PSP be moddable, let us put custom firmwares on. But make it immune to UMD piracy. Get devs to make good games for it.

i think that won't work. maybe (if this whole thing about deleting files is true) it looks for file types. maybe the UMD checks for certain file types and not folders named "ISO" or "SEPlugins". it prolly just looks for file types such as ISO, CSO, and PRX.

Okay then. Byebye PSP.

I've never pirated a game in my life. My UMD library has all the PSP titles I currently want to play, I don't have an R4 for my DS, I get all my PC games from Steam etc... Yet Sony think it's smart to not trust me and (potentially) delete my files?

That's the last blow. I won't be buying any more PSP systems or games. That's a serious breach of privacy all to stop a few (thousand) pirates.

You clearly haven't seen the numbers on BitTorrent.

Given the ridiculous amount of piracy on the PSP, I doubt developers would bother making ANY new games without seeing Sony do SOMETHING to prevent it.

And the comments on THIS blog are pretty disgusting.

First people don't buy games because "they aren't good enough," but then DJ Max Fever comes along (a game that had a hard enough time getting released in the US) and people STILL download the game as well as the patch, made to do nothing else BUT help people play their pirated game.

Now we have people complaining that they're "too expensive"... last time I checked, gaming was a LUXURY and not a right!
