The 4th episode of the 3-D one-on-one fighting game. The most advanced part in the series with a total of 21 characters. As like other parts of the series, in Tekken4 a few of the old characters like Eddy have been removed... and some new characters like Christie, Craig, Steve etc have been added.

- TRIVIA -
This is the first Tekken game which has the ring-based play system... i.e : the characters play within a ring-looking stage. Player can push his opponent to a wall... and then beat him while he's stuck between the wall and the player.
The supercharge (LP+RP+LK+RK) which existed in previous games has been removed in this game... it was quiet useful for making your attacks register as counter hits. Though it has been put again in "Tekken 5", the latest sequel to the series.
Registering juggles got harder in Tekken 4 due to the extreme reality put into the game. In previous games you could create long juggles in which some time the character would get hit even if he is far away from you and in reality you would have missed him. In Tekken 4, this reality made the juggling game difficult but more life-like.
Tekken 4's 'Airport' stage is heavily reminiscent of the common airport stages from the "The King of Fighters" series.
The character Steve Fox was originally going to be called Dean Earwicker. A few early pictures of this character actually had the name printed. The name Dean Earwicker later appeared on the Sony PS2 version as a Tekken Force enemy.
Scitron Digital Content released a 2 CD limited-edition soundtrack album for this game (Tekken 4 original sound tracks - SCDC-00181~182) on 22/05/2002.

- TIPS AND TRICKS -

* There's no hidden off-screen character so when a new character will be released you will see him.

* You can move your attack before the match is started, though you can attack.

0.135u2 [Nicola Salmoria, MAME Team]

NOTES :
- Hardware: Namco System 246 / System 256 games (Sony PS2 based)
- R5900 "Emotion Engine" - MIPS III with 128-bit integer regs & SIMD
- R3000 IOP - Stock R3000 with cache, not like the PSXCPU
- VU0 - can operate either as in-line R5900 coprocessor or run independently
- VU1 - runs independently only, has special DMA path to GS
- GS - Graphics Synthesizer. Nothing fancy, draws flat, Gouraud, and/or textured tris with no, bilinear, or trilinear filtering very quickly.
- SPU2 - Sound Processing Unit. Almost literally 2 PS1 SPUs stuck together, with 2 MB of wave RAM, a 48 kHz sample rate (vs. 44.1 on PS1), and 2 stereo DMADACs.

WIP :
- 0.136u4: NamcoPS2 updates [Guru]: Added DVD images for netchu02, soulcl2a, tekken4b, tekken51, sukuinuf and soulclb3. Moved Kinnikuman Muscle Grand Prix and Taiko No Tatsujin 9 to System 256.
- 0.135u2: Added namcops2.c driver.
- 29th August 2009: Alex's Rom Dumping Project - So today i have dumped the last 2 bioses from namco arcade boards. So this makes a total of six ps2 based arcade boards bioses: System 246 (A), System 246 (B), System 246 (C), System 256 (Rev_A), System 256 (Rev_B) and Konami Pyson. First of all, there are two versions of the system 256 board, an old one, and a new one, the differences are small changes on the mainboard and pb free on the last version, its easy to notice wich board you have, cause in the newer version you can read PB Free on the seccond dongle slot from outside of the board. I dumped the bios on both boards and matches 100%. Second: System 246 (A),System 246 (B) and Konami Pyson bioses matches also 100%. So that makes only 3 different bioses after all, i have decompressed the bioses and found that the changes are some modules updated and others missing betwen the bioses.
- 13th January 2009: Guru - A few packages arrived yesterday. From Japan we have a Namco System 246 Rack Ver.C + DVD drive and a Namco System 256 + DVD drive.
- 27th November 2008: Guru - Namco System 246 main board and various pieces incl. I/O boards, DVD drive, DVD ROM for Tekken 4 and security cart and cables arrived this week. It came from a pile of junk as faulty but all that was wrong with it was the CR2032 coin battery was dead so it kept saying "First Power On" and it never saved the settings or scores. Changing it fix it hahaha! So this one actually works, the previous one I received was not working. After assembling all of the pieces and getting it working, I re-tried the old one that arrived some months ago and I can confirm it's dead. I can also confirm that the DVD drive compatibility issues with System 246 are bullshit. The drive I received wasn't working, so I grabbed a random PC DVD drive and tried that and it works perfectly. I must say I was never a fan of Tekken but watching the smooth animation on my 29" screen at 31k is pretty amazing. Hard to believe it's almost 7 years old now.
- 22nd July 2008: Guru - Namco System 246 with Tekken 4 DVD and Magic Gate Dongle arrived.
