Friday Post: Adafruit and Black Mesa

Hey all,

It’s been a fun week.  I have been playing a LOT of Black Mesa on Steam.  If you have never played Half Life then I recommend you pick up this great fan remake of the original game.  If you HAVE played Half Life then you need to play this game and see how great it is.  It’s free.  It’s awesome.  It’s a lot of fun.  http://release.blackmesasource.com/

Today Adafruit linked to me again.  This time about my Battery Powered Pi and how I was using their 2″ screen.  That made my day 🙂  The screen is working out great!

On the news about the overclocking…Holy Crap does it make a difference!  Street Fighter 2 is now 100% playable, and i’ve been able to load D&D (a CPS2 game) and it play amazingly.  I’ll be getting some video of that up soon.  If you are using Raspbian, update and upgrade to the latest version.  It’s worth it.

Have a great weekend!

Friday Post: Stuff in the pipeline

Not much to blog about tonight.  My PCSX_ReARMed binaries are getting a lot of hits.  I’m really impressed by the performance.  This weekend I’m working on my NeoGeo controller project.  Got more of the parts I need and a bunch of the Arduino code written.

Still working on the Mednafen Emulator.  Their IRC channel on freenode is really active, so that’s a great sign.

Also, VIA Technologies tweeted my APC unboxing video 🙂  That was a neat little treat.

Have a great weekend everyone.

Raspberry Pi SD Card Corruption

Hey All,

So this week started off cool then took a turn for suckage.  I’ve been working on getting two more emulators working.  One is a Neo Geo Pocket Color emulator, and it works, but has some minor issues.  The other is another mass emulator like MESS.  The older version compiles, but the latest one errors out.

The reason I am not posting binaries at the moment is because my SD card’s filesystem got corrupted during a test I was doing, and won’t boot.  I’ve made a bit for bit backup of the card using DD, and I’m going to try and retrieve as much data from it as possible.  Luckily I have other SD cards to use.

I was hoping to have the binaries for NeoPop available tonight but I have to recompile them on the new SD card.  If you want you can click the link above and download the source and compile it yourself.

The other emulator I’ve been working on compiling is called Mednafen.  The old version (0.8) is available in Raspbian repos, so just do sudo apt-get install mednafen and you should be good to go.   Make sure you run it once, then edit the ./mednafen/mednafen.rc file.  There is a part that says video and it tries to use opengl, set it to SDL and you should be good to go.

Have a great weekend everyone!

Friday Post: Arduino Keyboard Joystick

Hey all,

It’s been a long week, and I am really glad I have a long weekend to sleep in.

When the Arduino Leonardo was announced I was really excited to see it have built in USB HID support and could act as a keyboard, mouse, or joystick.  I was even more excited to find out that my year old Teensy++ (Arduino compatible board) was based on the same chipset that the Leonardo now uses, and is able to act as a keyboard as well!

This is a new feature that was introduced in the Arduino 1.0 IDE.  You can now send keyboard presses with this simple line of code: Keyboard.write(‘a’);  If I wanted the Up joystick to be the up arrow on the keyboard, I would just use: Keyboard.write(0x0E); .

.

My goal is to use my Neo Geo AES controllers as an input for MAME.  The Neo Geo pads don’t have any control boards built into the unit.  The console itself interprets each pin individually, just like an actual arcade board.  The pad uses a standard midi gameport (DA-15) connector, with each pin representing one button.

My idea is to make a Neo Geo pad to usb adapter using the Teensy++ as go-between.  The Neo Geo pins will be wired up to the digital pins on the Teensy, and the Teensy Arduino sketch will interpret each button press as a keyboard press.

I’m looking forward to working on this project.  I hope everyone has a great weekend and a restful Labor Day.

Friday Post: Playstation Emulation on the Raspberry Pi!

EDIT: UPDATED BINARIES HERE – FULL SPEED ACHIEVED!

Hey All!

Happy Friday!  This week brings some really cool things for the Raspberry Pi.  First up, we have a Playstation Emulator that works under X in on the Pi.  It’s called PCSX, it’s OpenGL ES enabled, and while it’s not runnign at full speed, it’s a really cool display of the technology that can be powered by the Pi.  Binaries and Instructions below.

Download PCSX Binaries

To use this you will need CD ISO’s of your backed up PSX games stored on the SD card.

  1. Make sure you in a windowed environment.  If you are just on the command line, use the command startx.
  2. Double click on LXTerminal on the desktop or open it from the application menu at the bottom left.
  3. From the LXTerminal, type cd ~/ to get to your home directory.
  4. wget http://sheasilverman.com/rpi/raspbian/pcsx.zip
  5. unzip pcsx.zip
  6. cd pcsx
  7. chmod +x pcsx
  8. ./pcsx
  9. Use up and down to navigate the menus.
  10. Select Load, then navigate the directory where you saved the CD image
  11. Select your game then press enter
  12. ENJOY!!!

This emulator is far from perfect on the Raspberry Pi.  Some games won’t work, frame rates are wild, and it can be a bit frustrating, but who cares!  It’s a freakin’ Playstation emulation on the Raspberry Pi!

Second cool thing to come out today is an announcement from the Raspberry Pi foundation.  They are now selling licenses to enable MPEG-2 and VC-1 decoding, as well as H.264 encoding (free?) and CEC support!

I’m not sure how the license system works since it is somehow tied to your Pi’s serial number, but you can purchase them at the Raspberry Pi store.

Hope everyone has a great weekend!

Friday Post: APC.io

Lo all.  Happy Friday everyone.  This post is going to be kind of short, as I somehow hurt my back and I can’t find any really good position to type in.

This week the Via APC single board computer went on sale at Newegg.  This is kind of a competitor to the Raspberry Pi, except it only runs Android 2.3 right now.  It’s also more locked down than the Pi, and is almost twice the price, at $55 after shipping.  I haven’t had it long enough to do a good review, and yes, I know I sound negative about it, but what I’m really hoping is it will be able to run Unity 3D engine games.  It’s already impressed me with it’s out of the box Youtube app.

Unity is an awesome game and physics engine, and to have an ARM based development board that can output 1080P and has normal PC interfaces could be pretty awesome for Indie Arcade Development.

Heres an unboxing video I took yesterday:

Have a good weekend everyone.  I have a surprise for tomorrow 🙂

Friday Post: Descent and photography

Hey all,

Another Friday post here.  A couple of days ago Derhass made a post about getting Descent 1 and 2 ported to the Raspberry Pi with OpenGL ES.  Descent was an amazing game released back in the early 1990’s.  It had true 6 range freedom of movement in a spaceship with 3D modeling.   An amazing game at the time, and one that I could NEVER beat.  I’m in the middle of writing a tutorial on how to patch and compile the game, as well as hosting the binaries themselves.

Today on the Raspberry Pi frontpage is a really cool piece on time lapse photography titled “Painting with light (and a Raspberry Pi)”.  The images are really fantastic:

Hope everyone has a good weekend.  I’ll be writing the tutorial up this weekend and should have it posted soon.  Thanks for the view!
