Fire Fox (set 1)

Arcade 1984 Atari Shooter Flying (chase view)
You pilot the fastest, most sophisticated plane on the face of the earth that has just been stolen from Russia. You fly through different areas shooting enemy MIGS and other FireFox prototypes. You must avoid Russian infra-red radar tracking and find the refueling points to make it further into the game. High altitude flying would use less fuel but would make FireFox more vulnerable to detection. Flying at a low altitude would use more fuel but would give you better cover from the MIGS.

Fire Fox (set 1) et M.A.M.E.

0.127u4 [smf]

LaserDisc required

WIP:
- 0.146: Couriersud improved sound emulation for POKEY chip. Changed audio emulation to emulate borrow 3 clock delay and proper channel reset. New frequency only becomes effective after the counter hits 0. Emulation also treats counters as 8 bit counters which are linked now instead of monolytic 16 bit counters. Fixed high pass filters for POKEY. Added POKEYN device based on modern device. Fixed random lfsr generation. Consolidated polynom code. Removed legacy left overs from pokey code. Added a internal pokey_channel class. Convert all remaining drivers to use the modern pokey device.
- 0.144u6: Aaron Giles fixed missing Laserdisc video from CHD and performance problems in Fire Fox. Replaced 'Laserdisc Analog' sound with 'Phillips 22VP931'.
- 0.143u4: Changed VSync to 59.940057 Hz.
- 0.143: smf fixed crash after OK in Fire Fox and clone. Re-added I8049 (11MHz) CPU3.
- 0.142u3: Removed I8049 CPU3.
- 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 firefox driver.
- 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 [Couriersud].
- 0.134u1: Couriersud updated Fire Fox to use "new" TMS5220 interface.
- 0.129u4: Changed Custom sound to Laserdisc Analog.
- 0.128u4: Aaron Giles and smf added Laserdisc to Fire Fox - Game now playable.
- 0.128: Aaron Giles and Phil Bennett connected Fire Fox audio enables and improved volume balance so you can hear the speech chip. Fixed speech chip frequency. Changed TMS5220 clock speed to 650826 Hz.
- 0.127u8: Cleaned up Fire Fox video implementation [Aaron Giles]: Proper sprite/tile priorities. Adjusted X offset to match screenshots. Converted to tilemaps. Fixed rom loading (sprites).
- 0.127u6: Aaron Giles changed Fire Fox to RGB32 to allow for mid-screen palette changes. Because of the above change, the hacky alpha manipulation that was previously required is no longer necessary; the alpha is set directly in the palette entry. Aaron Giles removed render_container_set_palette_alpha() hack. Now the alpha value can be set directly in the palette entry and will be respected for laserdisc overlays.
- 0.127u5: Fire Fox improvements [Aaron Giles]: Memory map is complete from schematics. Gutted laserdisc hacks in favor of actual laserdisc implementation. Fixed all CPU and sound clocks. Removed need for deprecat.h. Added Philips 22VP931 laserdisc emulation, which is mostly working. Communication works fine and basic searching/playback/skipping is functional. Still a bit glitchy. smf removed sprite to tile priority in Fire Fox, it doesn't exist. Replaced M6809 CPU1 with M6809E (7159090 Hz) and I8049 MCU rom (pr-8210_mcu_ud6005a.bin) with at-6-1_a.bin. Changed M6502 CPU2 and 4x POKEY clock speeds to 1789772 Hz, I8049 CPU3 to 11Mhz and TMS5220 sound to 715909 Hz.
- 0.127u4: smf added Fire Fox (set 1) (Atari 1984) and clone (set 2). Still needs proper laserdisc support.
- 28th January 2003: smf sent in a preliminary Fire Fox driver written by him and Chris Hardy, but the laserdisc emulation has not been done yet so there's not much to see.
