The 6809E has a 'Last Instruction Cycle' pin that is likely tied in with the encryption: "LIC is HIGH during the last cycle of every instruction and its transition from HIGH to LOW will indicate that the first byte of an opcode will be latched at the end of the present bus cycle". According to the QIX and Kram schematics, these games should be using 68A90Es. I merely provide tables to decrypt it, derived by comparison with the not encrypted versions. The Kram encryption algorithm is not understood. Space Invaders / Qix Silver Anniversary Edition Your opponents are the Qix and two Sparx. Claim more than 75% of the playfield for special Bonus. Scores based on area: 250 points for Fast Score and 500 points for Slow Score. Claim areas by joining walls with stix. To change the language, delete the QIX.HI file from the Qix directory and re-run the program. To leave the configuration screens, press F3. Your configuration is saved automatically and will be reloaded the next time you play. Change the configuration as desired, then re-enter the dipswitch menu and change the value back to "NO". Change the value to "YES" while not in a game.
In the dipswitch menu, "CONFIGURE CMOS" lets you change the game's settings by using the configuration screens. Press F3 to skip the configuration screens at the beginning. Interrupt timing should be exact now (NdMix). Emulation will be slow on anything less than a Pentium 133.
While in the configuration screens: F1 = Next screen, F2 = Next line, F3 = Reset/Start game, F5 = Up and F6 = Down. Control: Arrows = Move around, CTRL = Fast draw and ALT = Slow draw. Game is playable with accurate colors and no sound. 0.28: John Butler added optimizations to Qix and fixed several problems in Qix. 0.29: Qix runs correctly and without slowdowns (CPU execution is interleaved). 8th December 1997: Kevin Klopp dumped Qix II (Tournament). Aaron Giles added sound and support dirty rectangles in Qix. 0.30: Mike Balfour added clone Qix II (Tournament). 0.31: John Butler merged the Qix and Zookeeper drivers, they now also support rotation. Changed parent description to 'Qix (set 1)'. 0.35b3: Nicola Salmoria added clone Qix (set 2). 9th June 1999: Al Kossow added another version of Qix. 0.35RC1: Al Kossow added clone Qix (set 3). 1st August 1999 John Butler modified Qix to draw straight to screen bitmap. 0.37b16: Changed M6802 CPU3 clock speed to 921600 Hz and palettesize to 1024 colors. This is the first of many bezels courtesy of Gene at Vintage Arcade. Do - Ad_Enuff adjusted Qix artwork with a more correct black. Do - Added the instructions to the Qix bezel, thanks to BYOAC. Added notifications for when the display enable pin changes in order to drive blanking signals.
#Mame32 0.146 driver#
Updated the Qix and Spiders driver to use the new functionality. 0.115u2: Zsolt Vasvari changed the CRTC6845 emulator to optionally control the screen configuration and video rendering. 0.123u5: Zsolt Vasvari changed Qix driver to use the MC6845's VSYNC notification for interrupts. Changed description of clones (set 2) to 'Qix (set 3, earlier)' and (set 3) to 'Qix (set 2, larger roms)'. 0.133u2: Team Europe added clone Qix (set 2, smaller roms). So, based on the TAFA flyers, there are new bezels for Qix. After checking through The Arcade Flyer Archive, it seems there quite a few Taito Japan games that used this type of bezel, just with different colors. Do - gregf pointed out an auction for a Taito Phoenix bezel, which looked a lot like Rock Climber. Changed parent description to 'Qix (Rev 2)'. 0.146u2: Identified Qix (set 1) as Rev 2 and corrected the rom names. There are no dipswitches, press F1 to enter the service mode, then F1=Next screen, F2=Next line, F5=Up and F6=Down. Press F2 to enter test mode, then F1 to advance to the next test. You can use F1 to proceed through all the configuration screens, or just reset (F3). The first time you run the game, it will ask the language.
