Artwork available


- Dark bands on trench are too dark; they should be lighter than the background. chowell (ID 02826)


- 0.134u3: Derrick Renaud fixed enemy shot sound in Space Encounter.

- 19th August 2007: Mr. Do - Let's play Space Encounters the way it was meant to be. To say this was complicated to put together is an understatement. A BIG thanks to Timothy from Outerworld Arcade for scanning and photographing everything, and even putting up a video of the game to see how it was supposed to look in the end. And another BIG thanks to Zsolt Vasvari to updating the driver a while ago, adding support for the tunnel effect and lamps. And though it's not listed below, I added a second "view type" using just the inner bezel and overlay, for those that are going to complain that the game screen is too small. NOTE: There are two more inside pieces to the game which we will get to at a later date. They still need to be restored for completion's sake, but wouldn't add much more to this point as they are almost completely hidden when viewing the game straight on.

- 0.115u4: Zsolt Vasvari fixed stobe light in Space Encounters.

- 0.114: Derrick Renaud emulated all sounds except the screech and wind sounds in Space Encounters. Replaced Samples sound with Discrete.

- 0.112u2: Canim fixed mapping of spaceship controls in Space Encounters.

- 0.112u1: Derrick Renaud updated Space Encounters to use the new PORT_REMAP_TABLE.

- 0.111u6: Adam Bousley emulated the trench circuit and Zsolt Vasvari implemented flickering of the strobe light in Space Encounters, to be eventually connected with artwork.

- 28th January 2007: Mr. Do - Zsolt hooked up the lamps for Space Encounters. I already have the lamps working in the LAY file for Space Encounters; just waiting on the necessary pics and scans.

- 0.111u4: Zsolt Vasvari and Derrick Renaud added SN76477 sound effect and lamp outputs to Space Encounters. Changed 8080 CPU clock speed to 1996800 Hz. Added SN76477 sound. Fixed rom names.

- 0.111u1: Robert fixed gfx glitches in Space Encounters, most notably the white line at the right edge of the screen. Changed visible area to 232x224. Added Samples (Invaders) sound.

- 15th August 2006: Mr. Do - Added Space Encounters artwork.

- 28th July 2006: Guru - Space Encounters (Midway 1980) and other games just arrived in 2 huge boxes. I think most of these are just for fixing issues in MAME (snd/gfx etc). Big thanks to Tingoes.

- 14th April 2001: Mathis Rosenhauer fixed the Space Encounters overlay to display correctly.

- 5th May 2000: Mathis Rosenhauer fixed a bug in Space Encounters artwork handling.

- 0.37b1: Artwork support in Space Encounters [Zsolt Vasvari]. Changed palettesize from 256 to 32770 colors.

- 24th March 2000: Zsolt Vasvari added overlay support to Space Encounters.
