[R4XKillaz313]

WOW, my game got compressed from 190 MB to 18 MB!!

[Ryuion]

Lol not a good thing this is, what if we still need ISO.... I sign PSP games and I hate ripping.

[gabriel25gatens]

hmmm why does it say my pc is now on safe mode?

why cant i open any files?

[martycoolboy1]

thaaaaaank you man this is sick! a game from 1.3GB to 630MB!!!!

[hatokopost]

thanks you for ruining my day myspace is only 2GB and the game is 2.7GB then when i compress it it became 2.6GB wow how many differnce is that from the first one wich means -(minus)100MB how could you call that best compression level the ISO to CSO link here sucks >:(

[andriux10]

Hey i got x64 windows, so i got error then i try to compres, any Ideas? Plz help

[Chipmunksdancehall]

Thanks man il try it out :D

[NadTheBat]

1.5GB to an amazing 1.45GB! All that time for a 50MB reduction! Thanks for wasting my fucking time!

[DownloadJunks]

@NadTheBat it depents on the game how big the differnce is , I was able to get my GTA lcs backup from 1.16 GB to 587 MB

[haha460]

if i compress it , can it still be played on my psp ? or does it lags ?

[hsbrasil]

WOW, its awesome, i converted a 180 mb game and now it have 26 mb, wtf!

[Jagordon13]

456 mb - 432mb woo hoo -_-

[hsbrasil]

@Jagordon13 Some games dont have too much thing to compress i think, same happened to me, but i tried to compress a 200 mb game and now it have 20 mb, lawl, working fine atm

[twofastrider]

can i also do this for .cso file??

[supernaturalforces]

.cso files are compressed iso files...u can't compress a compressed file...sorry

[niftynafter]

erm, i converted a ps2 game to an iso format, and it turned out to be 4gb++. can this work? or is there another converter for such huge memory games? i tried converting and it had an error asking me to send error report or don't send...

[jabjab1234]

This only works for PSP games...nothing else...and don't send.

[has214]

@jabjab1234 If CSO is just a compressed version of ISO does it still have the full game with all the features as ISO?

[donutman098]

@niftynafter read, its for psp

[shdie]

people, does this not work for the psp 3000, it does compress but it doesn't work for me.. i try to use cso files and it doesn't seem to work.... the screen just is black when u run the game in the xmb file

[DryYoshii]

@shdie

you have to mod your psp and install custom firmware (makes sense right!?)

[MrPurpleFreak]

i dont understand, i got that resistance game and it has 3 different files because its larger, how do i put all those together?

[Justin10473]

Did you download three different rar files?

If you downloaded three different rar files, and they look like (Name of rar) 1, (Name of rar) 2 etc, use WinRar to unzip them. Just double-click the first one, and WinRar will immediately unzip the next two and put them together.

[exia41gundam]

does the iso work on psp 3000(if it was from psn)

[koekii123]

omg why ur did faster? if i compress it needs 1/2 hours :S

[jnvproductions]

He probably had a better processor... either that or the fact that his file was only like 200 mb.

just saying

[LenooBroo]

thanks for the info..im gonna do my pes09 now.. =P..better than fifa09 but i think for the psp fifa got better graphics.but on ps3 and ps2 pes is wayyy better

[ronNarutocool]

does it make the game slower or reduce the graphics?

[andy41tuff]

THX xD

[RivalTech]

THANKS ;D

[ballnumber]

How do you download it?

It says find when you try to download it, is it like bittorrent and you have to have software to download it?

please help :)

[LilMissFlowerChild]

Huh ? where does it say find ?

[HHHHBKUSUCK]

if my game is 2 parts how do i put it in my psp?? help plzzzzzzz

[jabjab1234]

Just extract it as normal and then compress. Once you extract it will form into one file .ISO or .CSO.

[HHHHBKUSUCK]

ty DDD

[someonethehedgehog]

thanx

[ChinoManopreno]

instead of copressing an iso get hostcore so u can play with a usb cable

[rockster58000]

can u tell me how to compress a psp ISO or cso game that is in part 1 and 2

to make it into one file

thx

[shinbikyle777]

If it's an iso that is in an rar file put all parts into the same folder and extract the first file, and there should be another folder with the iso/cso file there.

[resou1]

can you make it any smaller? i have a 1.51 GB game.. but it only compress to 1.26 GB, and i have a 1gb mem stick

[searize]

my files are not loading wtf?!!!

[siralex64]

is this better then umdgen?

[englishpiff]

sory i ment only csos dont work!

[englishpiff]

i got 3.10 system software, i can play emulators, and use to be able to play games, now when i put on a iso or cso it sais: game could not be started (800...)

can anyone help?

[jabjab1234]

Have a play around with the drivers in the recovery menu. What do you mean you have system software ? You mean original firmware not the hacked one? If you have the normal one then you can't do it.

[Dr3d5]

u have to press select button,

then you set the UMD/ISO TO M33 / AN THATS THAT, AL YOUR GAMES SHALL WORK JUST FINE...

[guled69]

update it to custom firmware 5.00M33 that should make it better

[aznbandit1]

im pretty sure u have to have a game in the slot or else it will not start the iso etc

[hckmaster]

^ false

[Bonznumber1]

no you just have to press select when your on the PSP's XMB and goto UMD ISO mode and select m33 driver but if you don't do this then ya you need a game in the drive but even the demo disk will work

[mugabe999]

Hi man thanx for that i always thought u have to have a umd inside.i will subscribe to u.

[Bonznumber1]

ya you use to have to but it's nice that the m33 driver works well now... thanks for the subscribe

[WCGwkf]

my command prompt came up but it didnt start what do i do

[nightcrawler511]

lol mine got up to 300mb nd i got same game

[jabjab1234]

Yes it works on M33 firmware -_-*

[Representt]

whats the downside? more laggy?

[jabjab1234]

Hey, there is no downside..its not laggy at all and I'm using 3.52 M33 on the phat PSP and it runs smoothly even with newest games out :]

[Representt]

i've seen my cousins with fw 3.90m33 etc and compressed liberty city lags every 10 seconds. what i mean by lag is that it runs smoothly, lags for a bit, then runs smoothly again.

[jabjab1234]

hmmm, does he have a slim ? Doubt that would make much difference....umm maybe set the clock speed up to 333Mhz.

[Representt]

they just get there friends to put games and hack it for them, and yes they do have a slim. when i get cfw ill try to set the clock speed to 333mhz

[RachelTheDragonL0ver]

Thx for the info!but the compression takes a quite long time..

[rogerhendrix123]

Thank You jabjab1234, i also subscribed

[jabjab1234]

Thank you, sorry for the late reply..

[chronicsmoker817]

dude can i can compress cso? Its still too big but not as big as iso?

Thanks

[KRCkieranKRC]

very good tutorial my friend,, keep it up *****/*****

[jabjab1234]

Send you what ?....My video ?

[20Vizion20]

i try to compress some of the games but it wont show up when i look for it does that mean it was already compressed?

[bboyNoel]

does anyone kno how to rip out stuff to make it smaller? like additional languages, music, vidoes etc? thx

[Nzaine]

thx sooo much!

[ultimentgoku]

can you keep compressing the files so it can become small ANWSER MEEEEEE!

[Em0killer13]

no you cant , btw you sound like a retard . "ANSWER MEEEEEE!" .........

[badboychampionkilla]

thx for dat video cuz of ya i got iso compressor

thx man

[jabjab1234]

Yes, some people sometimes compress the game before upload so you guys don't have to. So your game is already compressed and ready to go.If you don't know how to play it you can check my other vid out on how to play ISO's/CSO's. Have fun.

[abethesk8ter]

how to compress a game with two parts like naruto heroes 2 help me pleas

[Dramaine]

Don't listen to that idiot. Download Umdgen v4.0 and put both those files in there and click save as .cso and there you go!!

[tommurdoch]

i can open the program fine, and so can everyone else here, its a zipped file so use WINRAR to open it

[Sinner7EX]

thank a lot dude .........very helpfull

[trimi38]

no because a cso is already compresed

[leksbeat]

Tried it and very pleased. Went from 864MB to 307MB. I compared it on my 42" HDTV and the picture quality was the same. The only thing that was different was the 864MB was bigger on the TV. But from a 864 to a 307, I can't complain. The best thing about the converter is that you can also unconvert it. If you don't like picture size on the tv you can uncovert it back to an ISO. Thanks for the video.

[xXxELEMENTxXxSFDM]

finally some one mk a video of it

[masterslyy]

thanks this works worked great from 520mb to 329mb thanks

[asiansarecool123]

well i have a question. I compressed my grand theft auto 1 gb into around 400mb. The thing is when i put it on my psp it doesnt work. I treid turning it into 1.50 kernal and all that, but it still does not work. I also tried uncompressing just to see if it works but the grand theft auto iso turns out to be 0 kb? why is that?

[jabjab1234]

You sure you compressed to .CSO it could have fucked up or something. I'm not sure mate sorry.

[onelasttitan]

all the compressor v 1.4 does is compress iso "image" files like worms.... is there any program that compress iso n cso "files" ?

[tommurdoch]

an "iso" or "cso" file IS an image

[andrewmsj]

but if ur psp is modified. it can open the game smoothly

[RiCaRdO408]

wat the hell?

how come i cant open the program?

[jabjab1234]

What do you mean, you need to give us more information so we can solve your problem. Do you get any error messages or...

[RiCaRdO408]

nevermind.. i found out how but its too confusing , you gotta download this program, you gotta do this and that and then you gotta download another program to put games on your psp i rather just buy the game

[jabjab1234]

You only need to download one program and you don't need a program to put the games on your psp.

[RiCaRdO408]

if you know how to then can you please tell me how to put full games on my psp step by step? and that are free not like that one website where you pay 37 dollars

[bankzhat]

thanx bro...it's works great...cheersss!!!!!!!

[jabjab1234]

This is for PSP not for fucking ePSXe. READ THE TITLE!!!!!!

[jabjab1234]

I don't think your supposed to convert a PSX .ISO. :s

[psychromesdead]

yo dudes ive got like the game socom tactical strike but its spreaded over 46 parts of RAR's

some1 plz help

i mean im like to friggin lazy to unpack all 46 files :/

[animechic25]

what you do is go to the very top rar file click on it while pressing shift then highlight it to the last rar file then right click and extract. if its spread out and not in order just press control while clicking each one.

[jabjab1234]

OR you can just make a file (whatever you want to call it) and then put all the game parts in that. Then just pick the first one and extract it and the others will be extracted in order by them selves. :D

[zael26]

i've got this 1gb card and i tried to compress but from 1.20GB it becomes 1.08GB can i still compress again?? plz help

[jabjab1234]

Nope, thats the best it can compress. SO I'm afraid your stuck with that size.

[chris34561]

what is CSO AND ISO and how do u tell which one u have

[jabjab1234]

ISO and CSO are just image formats. Usually before you download it will tell you. If not then just right click on it and then go properties and thats where it will tell you. It will usually say ISO or CSO file.

[Headucation1]

nvm sry i got it i had to choose CSO instead of iso

[Headucation1]

i have 2 csos and ive tried them on my psps and work but i want to compress them but when i look for them in the original folder its blank WTF but when i look into it its there but i cant c it when i choose which folder to compres

[jabjab1234]

You can't compress CSO's

[Headucation1]

yea i was a noob lol i found that out later csos are already compressed

[majorbb100]
