Fix for PSX4Droid Lag Identified

You may or may not know XDA member zodttd. If you use PSX4Droid (an Playstation 1 emulator for Android), then you owe this dev a thank or two as he is the one that created this app. The emulator runs fantastically well on most devices but it has a problem. As time goes by, performance decreases (you may see FPS drops). After seeing this, zodttd decided to look into the problem and found the culprit coding for this. He has provided his findings as a guide for devs to cook this solution into their kernels and roms.

Please leave some feedback for the dev in case you find some other “oddity” in the code.

Hi,

I am the author of psx4droid. It’s a PSX emulator that uses a dynarec. Due to the nature of this code I can have to invalidate the instruction cache on these Android’s ARM processors. Just like Yong must do in GameBoid.

I noticed performance loss on the Evo 4G, MyTouch 4G and potentially others. As do some people running GameBoid (though this emulator lays heavy on frame limiting as it runs faster than 60 FPS so it’s not noticed as much).

You can find more information in the fix thread.

Tactile: An Addicting Game with Beautiful Material Design

The game industry has been around for decades, catering to a wide spectrum of people, young gamers and elder ones, casual gamers and serious ones, and for an industry with such specifications, innovation isn't the only fuel for success. An increasingly large number of games draw inspiration from another and build on top of that idea, and Tactile is one such product, an excellently executed brainchild of a mashup between Tetris and 2048. For 2048 veterans, the game will come across as relatively familiar....

Android’s Consistency and The User Experience

This is a site of power users, and it is fair to say that most of us are more knowledgeable about Android than the average Joe. We tinker and tweak by customizing every corner for endless hours, until we arrive at a comfortable software configuration. In contrast, a large chunk of Android users don’t even use a different launcher - and many don’t know what a launcher is in the first place!   When we get so involved in our...

Which Manufacturer (And Device) Made You Choose Android?

The beautiful thing about Android is that there is so much to choose from. There are a handful of OEMs that design phones completely different from one another, so chances are you'll find something that suits your needs perfectly. Furthermore, Android itself is very open and customizable, giving users full control over their devices. With Google IO right around the corner, we'd like to know: Which manufacturer and device brought you over to Android?
