    You heard it first here, the PSP's killer app for this holiday season finally has a trailer.

    You can view it Here

    Here is what Rockstar posted with the youtube upload:

    Vice City, 1984. Opportunity abounds in a city emerging from the swamps, its growth fueled by the violent power struggle in a lucrative drugs trade. Construction is everywhere as a shining metropolis rises from foundations of crime and betrayal.

    As a soldier, Vic Vance has always protected his dysfunctional family, his country, himself. One bad decision later and that job is about to get much harder. Kicked out onto the streets of a city torn between glamour and gluttony, Vic is faced with a stark choice - build an empire or be crushed.

    Developed by Rockstar Leeds and series creators Rockstar North, Grand Theft Auto: Vice City Stories arrives for the PSP™ (PlayStation®Portable) system this October.

    Kagato from our forums has released a two new homebrew eboots. Here is what he had to say.

    By popular demand, I'm making Electris and Reactor available as stand-alone eboots.

    These eboots are configured for firmware 1.5.
    2.x users should stick with the Lua versions of the games for now.

    Thanks go out to Zion for his tips on using PSPBrew to edit the LuaPlayer eboot.
    I thought I'd need to recompile it from source, but PSPBrew meant I could have them up and running straight away...

    Electris remains at version 1.0 at this stage, and is essentially unchanged.

    Reactor has been updated to version 1.3, as I found that it ran considerably faster stand-alone. (I guess Lowser must have been consuming resources in the background.)
    The game was synced to screen refresh, so if processing one "tick" took just slightly longer than 1 refresh, it would play at ~30fps (which was typical before); if it took slightly less, it would play at ~60fps -- ie, double the speed

    This was unacceptable from a gameplay perspective, so in version 1.3 the proton's velocity is now Timer based. The framerate may change with CPU load, but the game should play at a constant speed regardless.

    I've also updated the particle sprites to have a chrome appearance, as a small visual cleanup.

    You guys asked for it and we are here to deliver. Its StrmnNrmn.

    Kaiser: I feel truly privileged to interview you StrmnNrmn. Thanks for giving us some of your time. I'd like to start this off by asking you to tell us a little a bit yourself.

    StrmnNrmn: I'm a 27 year old guy living in London, UK. I currently work as a quantitative developer for a large investment bank in the city, but this is a recent career change for me. Before changing jobs I had spent 5 years as a console programmer at a well known UK games company. I've found since changing jobs I tend to have more free time in the evenings, which is why I've been able to put so much effort into improving Daedalus recently. Besides work and programming, I enjoy running and try to play football regularly. I also play a lot of games

    K: What education and or qualifications to you currently have?

    StrmnNrmn: I have A-Levels in Maths, Chemistry, Biology and Physics and a BSc in Computer Science from York University. Since graduating I have 5 years of console (mostly Xbox) and PC development experience (but sadly just one
    released game )

    K: What got you into video games? and what was your first experiance with them?

    StrmnNrmn: My dad used to teach computing at a local school and used to bring home computers some weekends and holidays. They had all sorts of computers like the RML 480Z (http://vt100.net/rm/), the Dragon (http://www.6809.org.uk/dragon/gallery.shtml) and of course BBC Micros and so on. I used to play all sorts of games on them, but they were mostly just simple educational titles. A few years later one of my friends got a ZX Spectrum and I knew I just had
    to get one of my own. When I was around 10 I got a ZX Spectrum +3 and have fond memories of playing classics such as the Dizzy series, Rainbow Islands, Operation Wolf etc. I suppose this was when I first started to program. At the time it was mostly just copying in listings from the back of 'Your
    Sinclair' but as I got older I began to write my own simple games and programs. I think I've always preferred writing games to playing them.

    K: Can you go into detail about your previous forrays into homebrew and emulation previous to the PSP?

    I've not really done much in the way of homebrew before the PSP. I did convert Daedalus to run on the Xbox a few years ago, but never felt confident about releasing it. I've been working on Daedalus for many years now. I started developing it at my second year at university (probably around 1998) with the encouragement of my housemate (hello cms108 Progress has been pretty inconsistent over the years. I go through phases of getting quite involved with the project and make many improvements over a few weeks before my attention turns elsewhere. Since releasing the PSP port I've had no problem maintaining my interest though - I think this is in part due to changing to a job where I work more regular hours.

    So I've not really done much else in the way of homebrew. I have release a number of other programs in the past though. Without giving away too many details, if you've installed Winamp over the past few years, you may have seen some of my other work without realising it

    K: What/who got you into the PSP and in-turn developing for it?

    StrmnNrmn: One of my good friends 71M (http://easy-monkey.co.uk/) is behind most of my dealings with the PSP. It was after playing around with Lumines and Ridge Racer on his import PSP one day that I decided to order one. A few months later 71M started playing around with the pspdev toolchain and he persuaded me to check it out. I actually got Daedalus ported around September or October last year, but it was 71M that finally persuaded me to release it publically earlier this year. So thanks 71M!

    I want to take this opportunity to thank the guys at ps2dev.org for all their hard work on the pspdev toolchain. It's fantastically well made and maintained.

    K: What was been your favorite homebrew app or game to date?

    StrmnNrmn: I actually don't get to use that much homebrew as my unpatched v1.0 psp is almost always hooked up to my PC for development. I don't tend to run any homebrew on my other psp as that's usually patched up to whatever version of the firmware Sony have decided to distribute with their latest releases.

    That said I do use Raf's PSPRadio quite often as it's awesome to be able to listen to Shoutcast streams anywhere in the house. I couldn't end this bit
    without plugging some of 71M's projects - namely FileAssistant++ (http://psp-news.dcemu.co.uk/fileasistant++.shtml) and his newly released Trigonometry Wars (http://www.easy-monkey.co.uk/TrigWars/)

    K: we all know and love Daedalus but do you have any plans to create/port other emulators or homebrew for the PSP or any other platform for that matter?

    StrmnNrmn: Daedalus PSP is taking up pretty much all of my spare time/energy at the moment. I think there's a long way to go yet with Daedalus before it comes close to achieving its potential. I want to do the best possible job of it that I can which means giving the project my full attention. Maybe you

    Our next entry into DCemu's summer series comes from another resident of DCemu by the name of Deniska. Deniska is known as the PSP homebrew gaming king and has released such quality games as KETM.

    Kaiser: Thanks deniska for allowing me to interview you. I've been a fan ever since the first version of KETM. As usual I'd like to start this off by asking you to tell us a little a bit yourself.

    Deniska: My name is Denis. I am 34 y/o. Although originally from Moscow, Russia, last 14 years I live in New York, USA.

    K: What education/qualifications do you have?

    I work as a software developer for a pretty big firm, developing web based applications. I have a degree in computer science.

    K: What was your first video game experiance?

    Deniska: Some 20+ years ago I ran across some zx80 based pc from Yamaha at school, running a pretty cool 2d shooter ( I forgot the name). That's then I realized I needed my own computer. Since not too many of them were available in Russia at that time, I put together my own version of Sinclair's ZX Spectrum and pretty soon was playing Commango and 1942.

    K: Do you have any past homebrew programs previous to working in the PSP scene?

    Deniska: I wrote a couple of java games for my symbian smartphone, SX1, from Siemens. One of them, an Arcanoid clone, called Javanoid :-) was ranked pretty high by JARS... Then, I lost that bulky phone during waterskiing and stopped writing code for it...

    K: What/who got you into the PSP and in-turn developing for it?

    Deniska: I was pretty excited when kxploit/Hello_world_psp came out, but PSPSDK realy triggered me in to trying to compile something for PSP.

    K: Mind telling us your first homebrew game/app for the PSP?

    Deniska: Kenta Cho's Noiz2sa was the first game I ported. I always liked that small and somewhat strange shooter. I desided to port it to PSP so I could play it on my way to work. It took me a while to finish the project, since some of the currently available calls and libraries were simply not there at that time. I got a bit creative with Noiz2sa, changing the color scheme, rotating the game 90 degrees, adding background, etc. Technically, it was not a straight port, but original author did not mind. It all worked out for the best and Noiz2sa won the 1st prize on one of the DCEMU coding contests. I still sometimes play this game on a subway.

    K: What was your favorite past homebrew project?

    Probably KETM. Although the original linux version had a pretty cool 2d engine, it did not shine much, mostly due to bad graphics and lack of level data. With some help from bourbon_bot I turned this game in to a pretty good 2d shooter for PSP with 5 levels, tons of enemies and powerups. The funny part is that the original author back-ported it linux.. He said he liked my version better :-)

    K: What current projects are you working on or plan to start on in the near future?

    Deniska: Mapviewer takes up most of my time now. The link below has some details about this project:

    K: So what homebrew/apps do you keep on your own PSP?

    Currently, I only have IRShell, PSPLink, Noiz2sa and KETM. I had to delete everything else for now, since I am experimenting with numerous maps for the mapviewer and they take up a lot of space.

    K: Do you have a favorite coder?

    Deniska: I don't really want to pick favorites, but there are ~20-30 people (and I am nowhere near them) who really shape the PSP hombrew scene. Some of them get the credit they deserve and other don't. I think that the creators of psptoolchain, PSPSDK and PSPLink should get more recognition.

    K: What do you think about the PSP scene in its current state?

    Deniska: Obviously, the scene is blooming now, with all the downgraders, custom firmware and custom chips available. This all draws a lot of new and talented people. Almost every day some new good game or application comes out. As for the fans - most of them are great, although some act a bit childish. A little more courtesy and respect would definitelly help the scene...

    K: As for commercial gaming which consoles, games and/or genres do you find yourself playing the most?

    Deniska: I have a few games for xbox 360. I play Ghost Reckon and Burnout the most...

    K: Would you mind leaving us with a few words of wisdom to aspiring PSP coders?

    Deniska: I am not that old to preech yet ;-)

    K: LOL Thank you so much for taking time out of your life to allow us to interview us. I look foward to your next big release.

    deniska posted this rather interesting DIY guide over at his site (deniska.dcemu.co.uk) showing a rather interesting way to make your PSP connect and communicate with a GPS device.

    Here is a farely simple way to connect your PSP to a GPS receiver:

    You'll need:

    - Holux GPSlim236 (~$100)
    - Intec G6704 PSP Remote Control (~$11). Alternatively you can rip the connector of your original remote control.
    - USB (Mini B) cable ($5-10) (don't use the included USB power cable)
    - 1K 1/4watt resistor (>$1)
    - Electric tape ($2 roll)

    - Soldering iron
    - Multimeter (for checking the connector pins, alternatively you can use just a circuit made out of a low voltage bulb and a battery)
    - Razor blade (to cut and clean stuff)

    Basically, you just need to cut the USB cable and PSP remote plug, figure out which wires go to the connector pins, listed below, and connect them according to the diagram:

    Use caution when connecting the wires, make sure all of them are carefully insulated. You don't want to short any of them, since this may brick your PSP or GPS device.
    Also, GPSlim 236 spec says that the TXD voltage may range from 3.2 to 5 V, so 1K resistor may not be enough to lower the voltage in some cases. So buy a few resistors: 5k,3k,2k,1k and see if your circuit works with a bigger value resistor first..

    Once your cable is finished, test your setup with a little GPS viewer program that I wrote:

    The source code is included in the zip...
    Note, the program is written to work in kernel mode, so I doubt that it will work on 2+ fw..
    Perhaps someone can look in to how to adjust it...

    Here is the screenshoot:

    So, waht's the point you ask? I am planning to plug this in to the upcoming map viewer applcation, which, of course will be able to point your gps location on a google-like map in real time... and scroll the map as you move along...

    Special thanks to Art and futaris for helpping me out with serial port comm problems...

    Almost forgot a disclaimer: As always, I am not responsible for any damages...
