So what is Net Yaroze you might ask? Well it was a kit that allowed gamers to develop their own games at home or where have you. This unlike the actual DEV units could be purchased by anyone but didn't allow you to play pirated Playstation 1 games like the actual DEV units. Well this is a collection of all the games I can find that folks did with the legit development system provided by Sony and back when they actually were for homebrew development unlike the company we know now.

All the original folks that had to do with every Playstation system except the Vita have been long gone and now we are left with a bunch of corprate Gaijin's from SCEA running the show and running it into the ground faster then Sega it seems. If it wasn't for other markets I think the PS line would have become vaporware.

Anyhow back to the upload this is a collection of those games for you all to enjoy, no you don't need a DEV system or a Yaroze system to play these but you do need a way to boot backups just like normal PS1 disc. Whether that be swapping, boot disc, cheat adapter, or modchip it must be used to boot this collection of games.

It is all on one disc in BIN/CUE format for hardware and software users alike as BIN/CUE is the easiest to deal with. Comes with a neat menu to select games and of course scanned with CDMage to ensure no error's occurred and you have a valid image. Here is what you get on this sweet little portion of history.

From wikipedia


The Net Yaroze (ネットやろうぜ netto yarōze?, IPA: [netːo jaɽoːze]) is a development kit for the PlayStation video game console. It was a promotion by Sony Computer Entertainment to computer programming hobbyists in 1997. Yarōze means "Let's do it together!".[1]

Sony Net Yaroze with Software development kit.
For about $750 USD, the Net Yaroze (DTL-H300x) package would contain a special black-colored debugging PlayStation unit with documentation, software, and no regional lockout.[2] The user still had to provide a personal computer (IBM-PC or Macintosh; NEC PC-9801 was also supported in Japan) to write the computer code, compile it, and send the program to the PlayStation.
While without regional lockout, the Net Yaroze console exists in three variations; one for Japan, one for North America and one for Europe/Australia. The Europe/Australia version boots in PAL mode, while the others boot in NTSC mode. There are further differences between the Japanese kit and the others; the manuals come in Japanese, the software for Japanese PCs is included, and the discs and access card sticker have different printing. The Japanese version is sometimes unofficially referred to as DTL-3000 rather than DTL-H3000.
The Net Yaroze was only available for purchase by mail order; but Sony also provided it to universities in the UK, France (Epita) and Japan.[3]
The European Net Yaroze kit contains the following items:
1 Net Yaroze PlayStation console (black matte texture)
2 PlayStation controllers (black matte texture)
1 AC power cord (with UK plug; in France an AC adapter was also included)
1 AV cable
1 European AV adapter
1 Net Yaroze boot disc (a greenish PlayStation CD-ROM)
1 Net Yaroze software development disc (A CD-ROM containing development tools for PC)
1 Access Card (a black memory card-like dongle, required for booting in remote-controlled mode), with sticker
1 Communications Cable (a special serial cable used to link the console and the computer over a serial communication)
1 "Start Up Guide" manual
1 "Library Reference" manual
1 "User Guide" manual
Additionally, CodeWarrior was ported for the Net Yaroze, as well as Lightwave 3D.
The Net Yaroze lacks many of the features the full PlayStation developers' suite provides, such as advanced hardware, software, libraries, tools and Sony's extensive technical support (including live telephone support). Dedicated Usenet groups, with access restricted to Net Yaroze members, were maintained by Sony; homepage hosting was also provided. The access was restricted according to the kit's region of origin, which made collaboration between users in different territories impractical.
The Yaroze's primary RAM was the same as a standard grey PlayStation 1, which is 2 megabytes. However, Sony added an additional secondary RAM location, that granted programmers an additional 1.5 (3.5 total) megabytes of working RAM space. Game code, graphics, audio samples and run-time libraries, were limited to 3.5 megabytes, because the Net Yaroze drivers must be installed. There are many commercial PlayStation titles that are entirely RAM-resident and could have been developed with Net Yaroze while using the CD strictly to spool Red Book audio.
Many games made by hobbyists on the Net Yaroze were released on various demo discs that came along with the Official UK PlayStation Magazine (and other official PlayStation magazines around Europe) from December 1997 up to March 2004. The last Official UK PlayStation Magazine issue, number 108, featured a compilation with many Net Yaroze games. A regular PlayStation disc, featuring a number of user-developed games, was produced by SCEE and sent to PAL zone Yaroze owners.
Some of these games were based on arcade classics such as Mr. Do and Puzzle Bobble, while others (e.g. Time Slip) were illustrations of a novel concept. The Game Developer UK Competition, organized by Scottish Enterprise in collaboration with the Scottish Games Alliance, Sony and Edge in 1998, accepted Net Yaroze entries; the overall winner was Chris Chadwick for his game Blitter Boy: Operation Monster Mall. An updated version of Time Slip was later released for Xbox Indie Games in February 2011 and Windows in January 2012.[4]
Contrary to popular belief, the Net Yaroze was neither the first nor only official consumer console development kit. The PC-Engine Develo predates it, and the WonderWitch followed it. The GP32 can run user programs out of the box. Finally, many earlier consoles (Astrocade, Famicom…) offered limited programming capabilities with BASIC dialects.
The Net Yaroze had no direct successor on the PlayStation 2 platform, but Sony's Linux for PlayStation 2 is similar in its appeal to hobbyists and amateur developers, although the demo disk that was bundled with the system on release had an application called Yabasic and allowed users to program in basic and run on the PlayStation 2 system, it came preloaded with some simple games and users could save their programs to the memory card.[5]
Prior to the 3.21 firmware update on April 1, 2010, the PlayStation 3 (only the "fat" version, Linux could never be installed on the "slim" version) allowed versions of Linux to be installed and some Linux programming was possible, similar to the PS2. However, access to the RSX graphics chip was prohibited, so games had to be written in software using only the CPU. PC as needed with at least these minimum requirements.

Net Yaroze System Requirements
Operating system IBM or Macintosh
CPU 66Mhz
Memory 4Mb
Hard drive space 10Mb
Graphics hardware SVGA monitor compatible
Sound hardware None
Network 28.8kb/s

Also I am not sure it is Japanese but I don't think it matters in the PS1 swapping like Saturn. Sorry can't test as I have chips in all mine but the system was Japan only so I just used this nifty thing called logic.

Out of the 39 games, the only game with color is Fatal Fantasy VII. The rest are in black and white

Sounds to me your TV doesn't support the proper resolution. Also have you done the color correction mod to your system?

Dunno what the deal is over in the US but playing NTSC games on most older PAL consoles requires an RGB scart to give colour picture (PSX included)

Dunno all work for me with my xrgb scaler as my tv supports pal resolutions so it just might be my setup that gives me color but never had any troubles with pal games from any system.

You're welcome. Just to give you a heads up. I tested it with 2 tv. And 1 appeared in color and the other black and white. Maybe it's my tv, I'm not sure

Thanks Atreyu. Any chance of a NTSC, or does it not exist anymore?
