PPSSPP v1.0 released

PPSSPP VR Cardboard

Henrik just released new official version of this great psp emulator. This time come VR Cardboard support and more improvements. This is what he said,

1.0 has been released!
Obviously, this doesn't mean that every bug has been fixed, but it's still an important milestone. Just look at the list of new features:


* Many, many bug fixes in JIT and elsewhere, improving compatibility
* Proper fix for Zenfone and related devices
* Direct3D 9 supported as a rendering backend on Windows, helps on old GPUs and can be faster than OpenGL in many cases
* You can now create specific configs per game
* FPU rounding modes much better supported, fixes the Peace Walker boss that was undefeatable. NOTE: This breaks saves in Gods Eater - you must turn off the better rounding, load your save game, turn it on and save.
* The JIT now uses SSE on x86, improving speed considerably. This does not affect ARM devices, that's for the next version or two.
* Improved audio output code on both Windows and Android, reducing audio latency on Windows and on some Android systems
* FFMPEG upgraded, fixed some music hangs ("GHA phase shifts")
* Some Ad Hoc improvements, is now default adhoc server. Ad Hoc still unfinished and hard to use.
* Graphics fixes: Bezier/spline drawing fixes, vertex position fixes, DanganRonpa on Adreno fixed, flat shading fixed, vertex cache improved, some PowerVR blockiness issues fixed, screen scaling filter added, Google Cardboard support
* Simulate UMD speed better, fixing hangs in several games
* More Atrac3 fixes, fixing hangs
* Somewhat better disk full handling
* Fixes to dynamic unloading of code, fixing problems in GEB and TRM 2/3
* Updated to SDL2 where applicable (Linux, Mac)
* Some new features, like analog/dpad-swap hotkey, graphics hack for Phantasy Star, show last bit of debug log in dev tools, etc

And many more!


no$gba v2.8 released - with DSi emulation

no$gba v2.8

Martin just updated his Nintendo DS emulator which now give support to DSi emulation. This is what he said from ngemu forum,

Just uploaded no$gba v2.8. The new version is now having real non-experimental DSi emulation. And it's more or less working with DSi software. So far, it's tested with two DSi cartridges, and two DSiware programs:
System Flaw (cartridge): Works, but the camera emulation is showing only a dummy picture with snow (which is making the game unplayable, since it misuses the camera as gyro sensor).
Cooking Coach (cartridge): Hangs for whatever reason. It doesn't seem to be related to DSi I/O ports, so it might be some more basic problem, like some of the new/bigger memory regions not being properly emulated yet, or some memory not being initialized as how the DSi firmware would do it) (running the game in NDS mode works, the problem occurs only in DSi mode.
DSi Browser (DSiware): Boots, but complains about non-emulated WLAN access point.
Flipnote Studio (DSiware): Hangs for whatever reason, might be the same problem as with cooking coach. Would be great if anybody figures out what is causing the problems!
DSi emulation requires a copy of the lower 32K-halves of the ARM7/ARM9 BIOSes (BIOSDSI7.ROM and BIOSDSI9.ROM). And don't forget to enable DSi emulation (default is still set to NDS mode, for better compatibility with games like Cooking Coach).
PS. Some advice on how to capture camera pictures under windows would be nice! I need something with good backwards compatibility (which would be probably directshow), and it should be something that can be implemented by plain source code (without code from external libraries).

Android Internal/External SD card stuck preparing storage

New Android devices might not have this issues. But I did encounter this problem lately.
It been a very long run with my LG Optimus 3D. To solve problem with stuck preparing storage, follow this solution.

android stuck preparing storage

Connect the smartphone/tablet to your PC.

Once connected, turn on USB mode so you can copy/move files from the tablet with your PC.

Once the internal SD card is mounted on your PC, format the internal SD card with your computer to FAT32 with 64k cluster/allocation size.

By using windows command line:

format /FS:FAT32 /a:64K X:

Unmount from the PC. Turn off USB mode. Reboot. You should be good to go.

You can move back your backup files earlier. Better one by one and test. In case there is files that causing the troubles. Good luck.
