Good News! I am looking forward to finally play Urban Runner on the PSP. Can´t wait for tomorrow. Thanks again for your great work.

Just to make sure (so you're not disappointed), you have a PSP-2000 or 3000 or Go, right? Because there's a memory bug with getting Urban Runner working on the 1000 that DrMcCoy is working on.

I have both, 1000 and 2000. But primary I use the 2000. I´ve already tested it (short) and it works great.

By the way there is a possibility to sign Hombrews for the PSP, so they run on every Official Firmware. The signing Tools can sign many Homebrews but ScummVM does not work. I think many people would love to get a signed ScummVM.

Signing doesn't work with ScummVM because of the way we do the plugins. Or more precisely, to make the plugins work we have to use non-relocatable code, and signing doesn't work with that.

It's possible to change the way the plugins work, but it's a LOT of work for a very small audience. With HBL and custom firmwares easily available, it just doesn't seem like it's worth the effort. Not to mention that I currently don't have the time to put into making such a change. Sorry.

That´s OK. Was just an Idea.

But I found a critical (PSP specific) Bug in Urban Runner.

When I Save the Game, the PSP writes the Savefiles (into the correct Directory) but don´t show up in the Load Screen.

When I import the Savefiles into the Windows Version of ScummVM, they show up and load correctly. The whole Problem does not occur in the Windows Version.

Hmm I remember something like this in another game. I think it was a capitalization problem of some sort.

Ok. I´ve downloaded the official 1.3.0 release and finally it worked. Loading of Savegames without any Problems.

Later I updated to a nightly Build and it still worked fine.

Yesterday I again updated to the latest nightly Build and the Bug was back!

Then I again installed the official 1.3.0 Release and the Bug was still there. Very Odd. How is this possible?
This Version worked previously.

[EDIT]
Ok. I´ve found something interesting. The Gamefiles are the following:

CD1.ITK
CD1.STK
CD2.ITK
CD3.ITK
CD4.ITK
INTRO.STK
OBJET1.ITK

Now when I delete only one of the CD?.ITK, the loading of Savegames works again. Even with the latest nightly Build. No matter, which of the CD.ITK Files.

When I create a 0 Byte File to replace the deleted File, the Bug occurs too.

So, it seems the Bug was never gone. It was still there all the Time. But for testings I did not completely copy the Game Files to my MS.
