So it seems that ScummVM for iOS is supposed to support retina display, from what I've gathered in a few other posts in the forum. However, between the build available on Cydia as well as the daily builds, I have seen no sign of retina support. For most of the games ScummVM supports, this doesn't matter, but it really makes Curse of Monkey Island look blurry. It appears to be downscaling it to 320x240.

I used some voodoo to show the iPod display on my computer, and have attached a comparison between the game running in ScummVM, and a screenshot of nearly the same screen from ScummVM on Windows. There is some compression on the screenshot that iTunes applied when I copied the image over, but you can still clearly see how much sharper it is.

You probably want to try "No filtering" as graphics mode.

I should have posted the original screen capture with no filtering, but it is still clearly downscaled. The fact that it is downscaled is much more pronounced with "No Filtering" enabled.

Here's a new screen capture to demonstrate.

Then I guess there's some info about supported displays missing in the .plist file. In theory ScummVM should support any resolution iOS returns to it.

I had a compiled ScummVM_1.5.0git.ipa floating around in my downloads folder and retina display works with it. I don't believe I used it initially because I was unable to get it to install. I just now installed it by manually copying the files and tweaking permissions. And I just tried the daily build again, even using the info.plist from the git IPA, and it does not work.

I found it somewhere other than the official website. I can find the link for it if you need it. As for the mouse issue, in the particular build I installed with that IPA where retina display works, in any mouse mode other than touchpad the mouse area is reduced to 1/4 of the screen. Also, I couldn't find anything specific to the plist that allowed it to use retina display, and using it with the current daily build made no difference.

EDIT: Here is where I found the compiled IPA. http://metaneutrons.blogspot.com/2012/02/compiling-scummvm-for-ios-iphoneipad.html

Not sure if it will help, but here are the contents of the plist.

Well the retina display issue appears to be completely outside of anything to do with info.plist. Regardless of what is in that file, the daily build does not display properly on my iPod. I just tried inserting the differences into the daily build's plist with no notable differences.

The pre-compiled IPA I linked to does display properly, but has the mouse issue, which makes games that need Click+Drag, ie: Curse of Monkey Island, unplayable.

This appears to be something to do with the iOS port's daily build code itself.. unless I'm just entirely missing something here. :/

I'm just really confused why then that that build works and the daily doesn't. If you can figure it out, I'd be very happy. Of course, having ScummVM at all is great and having it use the device's full resolution is just a nice perk. If you can think of anything you could do on the code side, I'd be more than willing to test the build on my device and report the results.

   

It should be working in the next nightly build.

   

I can confirm that this is working in the latest build. Thanks! Love the interface tweaks, too!
