Version 1.5 changes

By Malban - (http://vide.malban.de/).

• fixed diverse emulation hickups

  • SHIFT register is finaly shifting correctly (every second cycles instead of every first)
  • cycle exacter handling of analog hardware
  • added drift emulation (although you better leave it off)
  • added better analog timings (e.g. Clean Sweep display better)
  • 6809: clr instruction also READS memory
  • 6809: FAST RTI, CC flag was handled buggy
  • 6809: exg could provide wrong results in Reg A
  • VIA: interrupt flag for CA1 were not set in accordance to the CRTL register
  • VIA: T2 timer shift clock speed doubled
  • VIA: T2 low counter iFlag was not set correctly (Omega Chase)
  • VIA: T1 low counter iFlag was not set correctly (Vector Patrol)

• added sample support "OH NO SPIKE!"

• corrected bankswitching, full support for "normal" PB6 bankswitching

• also added support for Vectorblade bankswitchin IRQ and PB6

• added "dummy" emulation of flash support for Vectorblade

• saves in Vectorblade are actually written to the "bin" file loaded!!!

• added support for SpritesTM loading mechanism -> support for e.g. BadApple e.g. badapple.bin file (is about 200-300 byte) requires a movie file named like the bin with the extension ".vvm" in the same directory

• added support for "chassis" loading. The chassis must be in retroarch ".../overlay/VecX/screen.png" For this to work properly the display must be "hardware display" and use openGL.

• added support for "auto_sync" (cleaner display where is works) (synced with T2 timer...)

• added some configuration options

• changed the aspect ratio of the display and "shrinked" it a bit
