Speed issues with ISO

I have a PSP fat running 3.71 m33-4. I'm trying to play a Liberty City Stories ISO and I'm having major framerate issues, even with the cpu at 333mhz. AFAIK it's uncompressed (1.16Gb, .iso extension.)
I have a real memstick that hasn't given me speed issues in the past. I'm using the NP9660 driver.

So my question is are these just normal issues with this game or am I doing something wrong?

Well, the game can start to slow down at various spots, even on 333 MHz. Nothing unplayable though.

What brand memory stick do you have?

Compress it to cso and it won't lag(trust me)

Not likely frosty.
CSO only has the 8/10 read speed of an ISO. (Done over 20 samples)
Done the speed test by myself and my computer geek classmate.

Try playing GTA:LCS with ISO and CSO, get on to the fastest bike and ride it. ;)


No offence or anything.
 
Well it worked for me on VCS and FF7 CC, the ones that are over 1.2gb= lags w/ iso but cso= no lag. Iono about LCS, but i remember me fixing the lagging by compressing it to cso and 333mhz.
 
Understandable.
I don't think the size matter as much actually,
Jackass: The Game is 1.7GB in CSO but no lag for me as well.

I would say is that how the company had coded/ported their games for the PSP.

I should put some time on this research.
 
It'll lag if the memorystick has a heavy duty(basicly it's gta load a ton of data constantly(depends on the size of data source)) that i believe is the reason why big iso compressed to cso from 1.6gb to like 1.2gb becomes not laggy because the strain on the ms drops and it'll load smoothly and doesn't have any delay.
