DA made a program which speeds the ms up.
Now can someone make a program that does the opposite. Making the read-speed slower?

well.. I think you can do so like this:
first, get fatms IO driver by
PspIoDrv* ms_drv=sctrlHENFindDriver("fatms");
store its ms_drv->funcs->IoRead in a pointer(for example, OriIoRead)and hook it by your new func like this:
int SlowIoRead(PspIoDrvFileArg *arg, char *data, int len)
{
sceKernelDelayThread(len/100);
OriIoRead(arg,data,len);
}

But I don't think there's any use...

well.

you can use it to play backup's with a check that monitors the read speed. Games like DJ max fever.

Or perhaps not play backups, just a thought here...

You could take it a step further and adjust the delay based on the seek time the laser would take relative to the last LBA read.

DJMAX FEVER checks the read speed? First time hearing this..
is there any evidence (like reversed BOOT code) to prove this?

Its not the read 'speed'. Just checks if it takes 'long enough'. This can be worked around by suspending it in between, ejecting memory stick, etc.

So seems easy to crack then .. ?
PS: does anyone know the exact read speed of UMD driver?

This really isn't the kind of thing we should be talking about here, we all know "backups" is a euphemism and if you going to start talking about cracking then this is where the thread gets locked :)
