- Explosive pattern of Giddo Spario is different from the real one. Fujix (ID 00433)


- 0.143u8: Kanikani fixed DIP locations in Xevious.

- 0.141u4: Changed description of clones 'Xevious (Atari set 1)' to 'Xevious (Atari, harder)' and 'Xevious (Atari set 2)' to 'Xevious (Atari)' and 'Xevious (Atari set 3)' to 'Xevious (Atari, Namco PCB)'.

- 0.139u1: Alex Jackson fixed Xevious from reboots or hangs.

- 21st July 2010: Tirino 73 dumped Xevios (alt) (1983). This rom file comes from a bootleg PCB.

- 0.131u1: TH60 added clone Super Xevious (Japan).

- 26th July 2008: Mr. Do - Funny story. Tormod sent me a BUNCH of instruction cards a long time ago. You've probably been seeing them added in every so often. Well, around July of last year, I had completed a whole bunch of them, but then had a computer crash, and they ended up on the "spare" hard drive by mistake. I found them again going through a cleanup. So thanks to Tormod, this week we have Xevios.

- 0.118u4: Alex Jackson fixed the conditional extra lives dipswitch in Xevious.

- 0.114u1: Nicola Salmoria added actual emulation of the microcontroller used for the Namco 50xx chip as found in Bosconian and Xevious. Added MB8842 (256000 Hz) CPU4 and 50xx.bin cpu4 rom (Namco 50xx internal ROM - 2k). Replaced MB88xx CPU4 with MB8844.

- 0.112u2: Replaced 3x DAC sound with Discrete.

- 0.112u1: Replaced implementation of Namco 54xx sound chip with new MB8844 CPU core running the original embedded ROM code. Removed old sound core [Nicola Salmora, Ernesto Corvi, Guru]. Added MB88xx (256000 Hz) CPU4 with 1k rom and replaced Namco 54XX and Samples with 3x DAC sound.

- 0.111u6: Aaron Giles changed Xevious to use irq0_assert_line instead of irq0_pulse_line to prevent it from dropping interrupts.

- 0.109u3: Robiza increased the interleave in Xevious to fix synchronization issues.

- 0.103u4: MASH fixed number of credits in Xevious.

- 0.90u3: Derrick Renaud added proper filters to the Namco52 sample player of Bosconian, Galaga, Pole Position and Xevious. Adjusted relative effect volumes per schematics.

- 0.90u2: Derrick Renaud updated the Namco 54XX noise sound and added the R/C values to Bosconian, Galaga, Pole Position and Xevious.

- 0.89u5: Jarek Burczynski improved the Namco 54XX Noise Generator (Type A and B emulated, type C algo still unknown). Removed Samples sound and explo1-4.wav samples.

- 1st April 2000: Guru - Dumped Xevios (Bootleg).

- 9th October 2001: William Kucharski submitted a fix for Xevious cocktail mode.

- 0.37b16: Added samples explo3.wav and explo4.wav. Changed the 3x Z80 clock speeds to 3072000 Hz.

- 2nd July 2001: Satoshi Suzuki updated the Xevious driver, adding two new samples and adjusting clock frequencies.

- 6th January 2000: Nicola Salmoria fixed Xevious reset bug.

- 10th December 1999: Vernon C. Brooks fixed a Xevious drawgfx bug.

- 0.36b6: Replaced 8k main/supcpu roms with 4k. Added new color and sound proms.

- 22nd September 1999: Nicola added a correct transparency PROM to Xevious.

- 0.36b1: Nicola Salmoria fixed sprite flipping in Xevious.

- 11th July 1999: Nicola fixed Xevious's colors when enemies used the zapper weapon, and also shortened CPS1 graphics drawing functions.

- 0.34b1: Added sound and color proms ($0, 100, 200, 300, 500). These are probably not the original PROMs. The transparency information (bit 7) is missing.

- 0.33b7: Changed 'Xevious (Atari/Namco copyright)' to clone '(Atari)' and '(Namco copyright)' to parent 'Xevious (Namco)'. Renamed (xevious) to (xeviousa) and (xeviousn) to (xevious).

- 0.29: Valerio Verrando added high score saving to Xevious. Known issues: Sometimes explosion sprites appear at the top of the screen.

- 0.28: Tatsuyuki Satoh made several fixes to the Xevious driver. Dipswitches now work in Xevious [Nicola Salmoria]. Also fixed a bug in the targeting cursor colors (black corners while firing). Super Xevious works. Explosions are emulated with samples, thanks to Andrew Scott.

- 0.27: Mirko Buffoni and Tatsuyuki Satoh provided a preliminary driver for Xevious (Atari/Namco copyright) (Atari 1982), Xevious (Namco copyright) and Super Xevious, not working yet. To start the game, press ALT (sorry - will be fixed in a future release). Control: Arrows = Move around, CTRL = Fire and ALT = Bomb. To start the game, press ALT (sorry - will be fixed in a future release). Known issues: The sound works, but at the beginning it plays and endless sequence of "coin inserted" sounds. That's because it believes you have inserted 80 coins. After playing for a while, it becomes normal.

- 0.23: Nicola Salmoria and Mirko Buffoni added a very preliminary driver for Xevious.
