In 2016, I spent most of my spare time hacking away with the old playstation, Net Yaroze.
You can see all my Net Yaroze blog posts here.
My previous experience with the Net Yaroze was back in 1999.
I bought it after seeing a UK OPSM (Official PlayStation Magazine) demo disc video saying it was discounted:
At the time I was a IT student (Computer Science), I started in software development, programming C/C++, win32/MFC/OpenGL and Java.
But I majored in information systems (Enterprise), in the mid/late 1990’s business ERP products were all the rage!
It took me about a year to go through the manuals and Black Art of 3D Game Programming before actually starting anything substantial.
On my Christmas break of 2000 for 3 months, I remember being locked away in my room and crunching so hard, I was actually looking forward to the start of uni!
I learnt how to master the clunky 3D format and made a 3D side scrolling demo, with animated block people, very much like minecraft.
Dino Dini, started his game development career in 1979 with the Acorn System (kit) and the BBC Micro (8bit micro computer)
In the late 80’s after university, he went on to make Kick off 1 & 2 and Player Manager games for the Atari ST and Amiga, 16bit micro computers.
Dino, received two Golden Joystick Award (Game of the Year) for both Kick off games.
Next he created GOAL! for Amiga, Atari ST, and ported it to the SEGA Mega Drive/Genesis calling it Dino Dini’s Soccer.
In the mid 1990’s he went to the USA and worked on many playstation 1 and N64 titles.
He then went on to teach game development in a Netherlander university.
Rob Swan, started his game development career in 1997 with the Net Yaroze 😄
He made some very well known games on the PS1, thanks to the Official Playstation Magazine (OPSM) Demo CD’s (PAL regions).
His most famous PS1 game being Adventure game:
Up to 2015, it was still relatively hard to get an ‘indie’ (bedroom/hobby coded game) onto a console.
The only exception being Android consoles (micro consoles), now just called AndroidTV boxes.
A while ago I found out about the Xbox One Dev Mode, which was launched in March 31 2016.
It basically turns any retail XBox One into a UWP device (Windows10) and you can target it via Visual Studio 2015 (community edition is free), Unity3D also has UWP support.
This feature, is still new, with UWP officially launching on XBox in 2017.
You need a DevCenter license (19USD once off) which lets you put apps on the Microsoft store.
When the XBox is in Dev Mode mode, it’s limited in memory and CPU’s it can use.
I’m not interested in using C# nor DirectX, but there is a Microsoft openGL wrapper called Angle which is in C++ and supports UWP.
This is pretty good of Microsoft to do this!
Sony unfortunately, doesn’t have a real ‘indie’ friendly platform, requiring a business entity.
Here is my analysis about the unfortunate turn of events of the Retro VGS/Coleco Chameleon
Here are my thoughts, not about what happened with the fake prototypes etc but about the hardware and game cartridges.
My background: I was excited about the Ouya when it was kickstarted, but decided to wait for the retail units, I’ve glad I did because the hardware was disappointing, I eventually got a Madcatz Mojo and was excited about it, now the ShieldTV is taking the glory from the hard work of former microconsoles.
I am also an original Net Yaroze Member since 1998.
I’m not some much a game player these days, instead I enjoy the craft of good gamedev, and I don’t mean AAA, stunning graphics.
The Retro League Podcast EP:328 @9:55 has a good and logical explanation about it.
Basically, it’s a canceled cartridge based game console which used the Coleco brand name.
The hardware was to use FPGA) which allowed games programmed for any retro gaming hardware ie (Coleco, NES, SNES, atari 2600, etc) to run via HDL, this is explained well in their RetroVGS FAQ:
“If a developer wants to make a Neo Geo game, they would include an HDL (Hardware Description Language) file that configures the FPGA to operate like a Neo Geo.
The developer would code their game to run against the Neo Geo platform.
This HDL code along with the actual Neo Geo game will be on the cartridge.
Once that cartridge is placed in the RETRO VGS, it will become a Neo Geo and play that game.
So in this case, the language is: 68000 and Z80 code.
If you wanted to do a new Atari 2600 styled game, you’d include a 2600 HDL file that configures the FPGA to replicate the logic of the original 2600 hardware and then you’d include your new 2600 game on that cartridge too.
These two files are then paired up on the cartridge and when plugged into the RETRO VGS, will turn the console into a 2600.
So the language that would be used in this case is: 6507 (6502 with less address space). “
They didn’t mention old 8bit micros (Commodore 64, ZX Spectrum, Apple II), nor PC-DOS, Linux, OpenGL, DirectX, PS-X, N64, etc but I imagine it would have worked as all these systems are well emulated and reverse engineered.
So, basically game developers didn’t have to make much effort to convert their existing game (and working on original hardware (NES, SNES,etc)) to the Coleco Chameleon/RetroVGS.
Not only is the hardware ‘configurable’ it also has an ARM chip, if it’s a System On a Chip (SoC) chip it opens up even more possibilities.
“Oh and we’ll have a nice little ARM chip for some more fun stuff.”
So I’m working on a Net Yaroze game now (abbreviated to NY or Yaroze for short).
And as a Net Yaroze member, I have access to the old Sony newsgroups which I search when I get stuck in the hope of finding answers, which I normally do.. and sometimes it’s even my past self! lol! :/ doh!
Well… today I came across something worth sharing, see newsgroup post below.
Here’s a Commodore 64 intro I coded up on the Net Yaroze:
To the un-aficionados, The Net Yaroze, was the only game console, hobbyist development system, with an official retail release.
Now, If you look even closer at that list, the only other “true” 3D console in the same era/generation was the Nintendo 64! - 3D console games were still very new in the mid 90s.
Not only that, but it didn’t require assembly! (programming directly to the hardware)
It was programmed in higher level languages such as C/C++, Lisp and I’m sure others.
This was very important, as it allowed for easy porting (portability) from other non-assembly platforms ie DOS/Mac/other 32bit machines because it didn’t talk natively to any hardware.
It’s also a lot easier to read and write code and develop for and at that time C/C++ was being taught in universities anyway (before Java).
10 Years prior, when the 8-bit computers were in homes, their manuals included an explanation on how to develop for it, most commonly in basic.
But people taught themselves assembly and coded games and released them to the public.
Wikipedia says that the Develo PC Engine development accessory predates it, but it’s not a development kit.
A development kit includes a target device to run the actual target builds on, commonly a PC daughter board or a seperate unit.
So the idea wasn’t completely new, except it was the first gaming console to do it and the last unfortunately (XNA/PSVita aren’t retail hardware kits and the HYDRA kit isn’t a console, it’s a kit), .
But I still find it strange because at the time (mid 90’s) the idea of the ‘bedroom indie game developer’ was fading fast in popularity with the 16-bit micros and PC computers.
Mostly because games required better art assets and more complex logic, which one person couldn’t do as a hobby in a timely manner (a few weeks).
Links Net Yaroze & PSXDEV related material.
The Net Yaroze (which means, Let’s do it in Japanese) is was an official hobbyist programmable Playstation from Sony (SCEE).
It was launch in 1997, and I remember reading about it in a Playstation magazine, it was $750 US about $1400 AUD.
At that time I just started programming part-time, and I wasn’t sure I could do it.
In 1998 I started a Diploma in programming and in March 1999, I had a Net Yaroze! (I still have my acceptance letter in my CV!)
