Informazioni su bfcobra.c (Driver MAME)

0.113 [Phil Bennett]


- Complete blitter emulation

- Cobra II support

- Hook up additional inputs, EM meters, lamps etc

- All games bar qos: NVRAM not saved

- Viper does not have a colour palette - the Flare chipset drives RGB direct. To fix this I set default values in the palette when the machine is initialised

- CPU execution rate is wrong, the hardware adds 1 TCycle to each access which is unaccounted for.

- Plane priority is probably wrong but it's only used in Treble Top.

- Blitter loop counts and step are wrong - they are 9 bit counts, not 8.

- Blitter emulation doesn't support hi-res mode (needed for Inquizitor)


- Bell-Fruit Cobra hardware: The hardware is based on a chipset known as 'Flare One', developed by Flare Technology. It consists of a 16-bit DSP (intended for sound synthesis and 3D maths), an 8bpp blitter and a video controller, driven by a Z80. Flare One would evolve to become 'Slipstream', used by the unreleased Konix Multisystem console. The Flare One chipset is implemented as four Texas Instruments ASICs, each an 84 pin PLCC package: CF30204, CF30205, CF30206 (DSP) and CF30207.

- Other games: Brain Box, Every Second Counts, Inquizitor, Quizvaders and Treble Top.


- 0.148u2: Fixed BFCobra interrupt handling [Phil Bennett]. Fixing interrupt handling in BFCobra driver using 6809 that pulsed interrupts in a way that broke with the new 6809 core [Nathan Woods].

- 0.147u4: Bring 6850ACIA IRQ line into standard usage (ASSERT_LINE = IRQ active) [R. Belmont].

- 0.124u1: BFCobra improvements [Anonymous]: Added plane priority to blitter, fixing Treble Top signature writing. Video output now supports all modes (lores, hires, mixedres and 8/7/4/3 bits/pixel), fixing Every Second Counts colour problems. Added line draw, fixing missing stuff from Question Of Sport. Change blitter loop type control - there are 4 types of loop. Corrected video frame rate to 50Hz. Corrected Z80 speed to 5.91MHz. Accounted for Z80 cycles stolen during a blit operation. Improves gfx/sound sync and seems to fix the final round lockup in Every Second Counts. Changed visible area to 512x256.

- 0.121u3: James Wallace added meter support to the Cobra games. Cleaned up some of the steppers code.

- 0.113: Added bfcobra.c driver.
