the UMD Emulator you released yesterday didn´t ask me to input a button. it only returned to e-loader, what´s the problem?
sorry, my english is awful :(

The UMD emulator only mounts the ISO.

This program here is supposed to be able to read off the mounted ISO and gives you the option to copy stuff from the ISO to the Memory Stick.

So are we able to Load a ISO yet?

I have no idea what all that tech stuff means, but I really appreciate all your hard work and can't wait for the finished product.
You rule! : )

I just tested it. It works very well. I copied the PNGs from the UMD disc.

Hi I own a V2.6 TA-082 psp
I dun own GTA yet but am planning on bidding for a UK GTA LCS ULES 00151# unpatched version.

Will I continue to need the GTA after I apply the eloader once?

I'm a newbie please don't flame me.

At 8/10/2006 08:25:00 pm, Blogger Medieval Ånubis said...

@Vicki, yes, you do need to run eloader everytime you want to use homebrew on a TA-082 PSP. We're just out of luck.

Visit this thread for more info.

Good thing I won the GTA LCS ULES-00151# unpatched psp game then.

Hey sure sucks to be in a country where the game is banned and whatever stocks the shops bring in happen to be patched versions.

Er about the QJ link I didn't really understand the coding so I didn't know what was going on with all the flaming about piracy comments.

I just want to be able to stream videos to my psp with this via the homebrew PSPPIMP iso once this UMD Emulator gets updated in later versions.

hey all,

I installed everything according ro Ookm's info, and i got the "psp" screen just like if it was going to load my iso, but then i got an error message "80020148"
and it says "the game could not be started" i think this is just a sort of a trial for us to try and see that he (Ookm) is working on the program for us, and we should be patient. for now, just wait alittle longer people.....

uhh no you're wrong. First of all you tried launching it from the XMB or the PSP main menu. You're supposed to use the GTA exploit eloader to load the iso reader. I compiled it and it works. But you are right in saying that its only a sample and really can't do anything except read a couple of files of the UMD iso.

hey anubis, i wonder, did you get the same screen i got when i tried to load my backup iso from the GTA exploit? i was able to load fanjita's eloader, and it went to a black screen naming Ookm's umd emulator for 2.6
"UMD emulator 2.6 v0.03"
so i was wondering, do you think that the problem lies in alittle more tweaking of the eloader to be compatible with 2.6 to load iso, or is the product awaiting it's finishing touches by Ookm....

At 8/13/2006 11:42:00 pm, Blogger Medieval Ånubis said...

Its normal for it to go to a black screen. The reason for it is that due to the fact that the kernel exploit is prone to crashing randomly. In fact even simple text display could cause the PSP to crash. It did mount the ISO so don't worry.

You use the ReadUMD to read off the ISO. It uses a different mode so it won't crash.

All these programs are just POC (Proof Of Concepts) just showing all the possibilites available. Either 0okm or someone else has to develop them further into something useful.

try pspupdates.qj.net for more PSP info.

Oh, i see Anubis, but if this proof of concept could get this far, i suppose it's ok to hope for a solution soon. thanks for the link, i will check it out.

HOPE: the reason we live.

ookm when is it your next update for this UMDemulator, have you find a way to load the actual game iso

At 9/08/2006 02:24:00 pm, Blogger voso said...

sorry if this is a stupid question but do you use software to mount the iso's on the psp and if so what software do you use?
