The Empire Strikes Back
The third arcade outing based on the legendary trilogy of films; "Empire Strikes Back" eschews Jedi's Zaxxon-inspired gameplay and returns once more to the 3D vector graphics of the first game. Empire features four stages of play, with the first two putting the player in control "Luke Skywalker's" SnowSpeeder, and the second two in control of "Han Solo's" Millennium Falcon.
* The first level, Probots, takes place on the ice planet of Hoth, with the player flying the Snowspeeder over the planet's surface to find and destroy the Empire's search droids that are sending signals to the Empire warning them of the rebels' presence.
* The second Snowspeeder stage sees the player taking on the Empire's "AT-AT" Imperial walkers, as well as a number of smaller, bi-pedal "AT-ST" walkers. On this level, as well as the standard guns, the Snowspeeder is armed with a limited number of harpoons; these can be fired at the AT-AT's legs to send them crashing to the ground. AT-ATs can also be destroyed by shooting a small, highlighted area on the AT-ATs' head.
* The third level has the player piloting the Millennium Falcon and is a repeat of the original game's in-space Tie Fighter battle.
* For the fourth and final level the player must pilot the Millennium Falcon safely through a densely packed and fast-moving asteroid field.
Bonus points can be earned by destroying a certain number of targets. A JEDI letter will also be awarded in addition to the bonus points. Once all the letters that spell the word 'JEDI' have been awarded, players will have attained true JEDI FORCE, making them invincible to the Empire's forces for a limited amount of time.
In all levels of play, collisions with objects and enemy shots will cause damage to the player's deflector shields.

WIP:
- 23rd April 2011: Mr. Do - The day after the last release, I receive an email from LASooner, with an attachment called starwars.zip. I dropped in my artwork folder and played. After I picked my jaw up off the floor, I dug around and found the Star Wars scans from the BYOAC / CAG artwork, sent them back his way, and asked if he'd mind making it look even better. He took up the offer, and the end result is fantastic! So, we now have really cool artwork for Star Wars and Empire Strikes Back. Each file includes the full view, and a cropped view. Thanks again to LASooner. Maybe he'll grace us with some more surpises in the future.
- 0.139u4: Aaron Giles converted X2212 to a modern device. Changed X2212 device to return unmapped bits for the upper 4 bits. Added e2prom address space to X2212 so that the latched contents can be viewed. Updated starwars driver.
- 0.139u3: Aaron Giles removed vestigial NVRAM from Star Wars driver, which is now covered by the x2212 device.
- 0.138u2: X2212 now uses device template. Also changed all handlers to use devcb prototypes. Default NVRAM contents should be in region named same like device tag. Hooked up X2212 in the Star Wars driver [Couriersud].
- 0.137u3: Lord Nightmare updated Star Wars driver to use proper clocks for the TMS5220 and the Pokey's. Changed clock speed of the 4x POKEY to 1512000 Hz and TMS5220 to 672000 Hz.
- 0.132u1: Tafoid added DIP locations and made default settings changes to match manuals for The Empire Strikes Back.
- 0.126u2: Aaron Giles changed the 6532 RIOT device into a proper device. Rewrote the logic to be simpler and leverage the new attotime functions. Changed the I/O port setters to specify a mask, and changed the I/O port callbacks to pass in the previous value. Converted audio\starwars.c to use the new RIOT implementation instead of rolling their own.
- 0.123u5: Aaron Giles fixed game reset after start.
- 0.121u4: Mathis Rosenhauer implemented status flag in Star Wars matrix processor, which affects gameplay speed.
- 0.115u1: Changed region proms to user1/2.
- 0.113u3: Derrick Renaud fixed analog controls in Empire Strikes Back by adding back a faux VBLANK timing.
- 0.108u5: Mathis Rosenhauer rewrote the Atari vector generators, using the schematics and actual state machine PROMs. The state machine is now emulated so timing should be much more realistic. Clipping hardware in bzone and others is emulated instead of hardcoded. Improved accuracy of clocks and various other bits of cleanup. Changed M6809 CPU1/2 clock speeds to 1512000 Hz and VSync to 40Hz. Added prom ($1000 - AVG PROM). Removed flags dispose from region proms.
- 0.104u1: Mathis Rosenhauer improved Star Wars sound synchronization.
- 0.104: Mathis Rosenhauer fixed NVRAM handling in Star Wars/ESB (only affects test mode).
- 0.103u5: Mathis Rosenhauer fixed background music in Empire Strikes Back. Updated IRQ frequency and divider to match the schematics.
- 0.103u1: Mathis Rosenhauer rewrote the Star Wars mathbox multiplier from the schematics.
- 0.58: Changed palettesize from 256 to 32768 colors.
- 0.35: Renamed (empire) to (esb).
- 0.35RC2: Ernesto Corvi and Nicola Salmoria fixed the slapstic emulation in Empire Strikes Back. Changed input from 2 to 4 buttons.
- 23rd June 1999: Mathis Rosenhauer fixed the Empire Strikes Back mathbox chip, and the 3D vectors aren't anymore corrupt sometimes.
- 22nd June 1999: Marco Cassili fixed the dipswitches in Empire Strikes Back. Nicola Salmoria fixed Empire Strikes Back from hanging at the highscore screen.
- 21st June 1999: Nicola Salmoria finally fixed Empire Strikes Back's slapstic issues, and the game itself is playable!
- 0.34b8: Brad Oliver added 'The Empire Strikes Back' (Atari 1985), not playable.
STORY:
- It is a dark time for the rebels. The Empire has launched thousands of robots in search of the rebel hideout. The Empire fears the strength of the force within one rebel... Luke Skywalker.
PLAY INSTRUCTIONS:
- You begin with enough 'Force' to protect you for 4 collisions.
- 'Force' strength is lost when you collide with enemy shots, walkers and asteroids.
- Aim your lasers with cursor to explode Probots, Transmissions, Walker, Tie Fighters and shots.
- Avoid collision with asteroids by flying around them.
