CISO – PSP ISO Compressor

It took a while to figure out why it couldn't access my file system (permissions), and said my file was too large to decompress back to iso, not paying just for that.

Crashes instantly upon opening. I'm very disappointed with this app.

When I go to select input. Nothing shows up at all. But I can see the file plain as day in my phone and on the computer. I've already redownloaded the file twice still won't show.

It's complicated but I give it 3 stas

Even with storage permission applied..it cannot see or scan folders

It is now a crazy app with no goal

Thank you so much for this wonderfull app it helped when i was failing to play wwe 2010 because the psp emulator kept on saying it is still compressed.Thamk you very much

The you have made is very usefull. But can you make the "KEY" free to download or make it one with the original convertor. PLEASE!!!!!

I can't even see any of my folder you want us to try it ? or to buy it!

LOL, F U C K YOU! oh and eat $hit...

You should have made it paid if you had to force us to buy it I the first place

Bad bad app not work

Wonderful, truly succeeds at it's purpose. FOR THOSE WHO ARE STRUGGLING; you must go to your Settings/Storage and find this App. Then go on the Application Permissions and turn 'Storage' ON. If it is off then that is the reason you wil recieve the Java error.

This app is great! (For uninstalling). Extorts people for stuff you can do on a pc, while also raking in revenue from obnoxious ads. On top of all this, good luck getting it access your storage, even when you have manually enabled it. My assumption is that the uploader (won't call them dev) has took some open source, did and absolutely gash job of rehashing it, and tried to make money off it. No coding skills whatsoever here unfortunately. Avoid this, and use your PC.

People that are complaining ..are you thick or summit? This app is excellent and does what it says...and also to the people complaining because the key isn't free...shut the hell up already!!! Do you expect everything free of charge...people have to earn a living you know!!! Thankyou Dev for your hard work in giving us The ONLY Iso to CSO app available.

I am ok with ads on the app. But for paid users can you disable the ads that popup before the compression starts. I understand you still need to make money. Just for paid users no pop ups.

Simply doesn't work. Even after buying the pro key, converting a CSO into an ISO ALWAYS results in an "out of memory" error, and a 0-byte ISO file size. Even tested it on a 75MB CSO (Super Stardust Portable).

Its trying to make me buy it for it to work. You ruined it

It conveniently can't convert over 768mb without a "magical" key, Oh and the ads are obnoxious and persistent. Anyone with a pc can convert this without it's shameless key.

This null pointer error is a huge problem.I just can't access the file I want to convert.

Purchased licence key and allowed permissions to access the storage from the apps settings page and the app still isn't showing any of my downloaded Iso files

I assume that this is either a bug or I'm lacking second sort of permissions. I don't know the API that well. Note that I was using 6.0.1 on an nvidia shield tablet. Tried this on my 5. Something phone and it seems to work. Now to just transfer the file over

I have had no problem with this app. Only had one game I had trouble with, but it was a small file anyway. Very good for shrinking down files a gig or larger. One word of caution, spring for the unlock key or this app will really be of no use to you. Otherwise good app.

Im having trouble setting the iso file. I go to my downloads and the file file isnt popping up

Its trying to make me buy it for it to work. You ruined it

i can't find the rom I'm looking for. i know its downloaded but it won't appear. any ideas?

When it was paid with no ads. Now it has ads. Remove my ads please then I'll update to 5 stars

It DOES work but it's best in tandem with the compression key app that goes with this. This works very well indeed, chopping as much as 50-60% off the footprint of some smaller ROMs, while other, larger ones may only get a 15-25% compression, but when you're talking about files over 1GB, even that is a very handy per-ROM saving indeed and since it enables you to have more PSP ROMs in the same space, and since it's the ONLY app of it's kind on Android (I think), it's pretty obvious that everyone who emulates PSP on Android should have this app. A few things I noted, however; 1. The paid app let's you compress files of any size, so if you're trying to compress massive files and you didn't get the compression key app, you're screwed. 2. The paid app is only a 'key' so you need THIS one, too. It caught me out for a long time. I thought it was the switch I made to 5.1.1 but I think it was just coincidental that the nature of the paid app changed at around the same time, from a standalone app to a 'key' for the unpaid, main app. 3. I find NOT setting it to autodelete iso files after completing a compression will prevent crashes. On my Nvidia Shield Portable, it always crashes now whenever I tick that box. Until the developer fixes what I'm sure is a pretty minor problem, I think it's a small price to pay to simply delete the iso manually, afterwards. With the caveat of the understanding of the above 3 points, I have nothing but good to say about this app, it's perfect and can only really be bettered by doing more of the same. Having said that... it too much too ask that the developer make an app that can compress the files for ALL large ROM files? I have a heaving PSX library and sacrifices in my PC Engine CD and Saturn collection are having to be made. Nice app. Does what it says it will.

This null pointer error is a huge problem.I just can't access the file I want to convert.

My game won't work

Aplikasinya bekerja, sudah saya coba harvsetmoon leaf vakey dari 400MB menjadi 160MB, dan saya coba gamenya masih bisa ^_^, mohon di tingkatkan agar supaya bisa mencompres game berukuran 1GB lebih

This converter needs some type of guide, I am unable to select the folder that I want to compress, and I can't even set an output, overall clunky interface on large devices.

Null error keeps showing and I can't compress file. Please help asap

This application not show a iso file to convert, only show a cso file to convert iso. Please solve my problem.

This null pointer error seems to be the bane of everyone right now, myself included.

Totally waste of time and data so please dont install it

As far as I can tell this app works great here. On some games this app shaves around 500mb or more off the original file size.

What the title says.

Lol what a joke, I can't even find the file I downloaded.
