It appears within the last 24 hours that leaked footage of the PS4 interface has appeared online. It seems to be from an early test kit, so the final version in stores may be slightly different. Nonetheless, it's pretty cool to see how it's going to look like.

From the author:

Hi, I recently resumed working on my emulator and now I think I have enough to show. The gimmick of the emulator is the ability to display custom true colour tiles at up to 4x resolution.
BombSweeper is used as an example and a simple 2x graphics pack is included in the files which replace the number tiles. You need to download and put BombSweeper.nes inside the rom folder. You can play around with the png files inside the BombSweeper folder and see the results. The emulator is still in early stage and so lacks many standard features. Please read the readme for the limitations before using it. Feel free to comment and please let me know if you have trouble running the emulator on your machine.

Change log:

• Implemented showing leftmost 8 pixels of screen (bit 1 and 2 of PPU register $2001)
• Implemented colour emphasis (not accurate)

Description:

Change log:

Description:

MAME4droid Reloaded is developed by David Valdeita (Seleuco), port of MAME 0.139 emulator by Nicola Salmoria and TEAM.

MAME4droid Reloaded emulates arcade games supported by original MAME 0.139.

This MAME4droid version is targeted to Dual-Core devices (1GHz and 512MB RAM minimum), because it is based on a high specs 2010 PC MAME build.
Anyway don't expect arcade games of the 90 to work at full speed. With some games that are really bad optimized (like outrun or mk series) you will
need at least a 1.5 ghz dual-core device (Cortex A15). This is related to MAME build used, since it is targeted to high specs PC's as i said before.
This version doesn't have an UML back-end ARM dynamic recompiler, which means drivers based on high specs arcade CPUs won't be playable
(it has not sense since this games will be slow in any case).

Change log:

• Added tap on touchscreen as a lightgun device (only must be enabled for light gun games like operation wolf).

• Added Tilt sensor option to tap anywhere on screen to fire.

• Added game filterering (clones, favorites, year, category, manufacturer, driver source...).

• Some bug fixes.
