	CONTROL_PANEL.CAB:
	In "clipboard Hotstart.xml":

	FLYSIMWARE_DIMMER.CAB:
	X_3D_Gauges1_NIGHT.bmp
	 
	 
	FLYSIMWAREGPS.CAB:
	LEFT_2D.xml: Bitmap positioning; added Nav1 Audio Selector
FLYSIMWAREGPS.xml: Added power light, removed blinking "MSG", changed clcik behaviour for "MSG" button, modified macro assignments for key events
	 
	 
	LEARJET_35A.CAB:
	SYSTEM.XML: First element block added "0 (>K:AP_VS_VAR_SET_ENGLISH)"
SYSTEM.XML:
(L:SPOILER_SW, Bool) 1 == (A:ELECTRICAL MAIN BUS VOLTAGE,Volts) 8 > and if{ (>K:SPOILERS_ON) }    ==>    (L:SPOILER_SW, Bool) 1 == (A:ELECTRICAL MAIN BUS VOLTAGE,Volts) 8 > and (A:SPOILERS HANDLE POSITION,Percent) 99 < and if{ (>K:SPOILERS_ON) }
(L:SPOILER_SW, Bool) 0 == (A:ELECTRICAL MAIN BUS VOLTAGE,Volts) 8 > and if{ (>K:SPOILERS_OFF) }    ==>    (L:SPOILER_SW, Bool) 0 == (A:ELECTRICAL MAIN BUS VOLTAGE,Volts) 8 > and (A:SPOILERS HANDLE POSITION,Percent) 1 > and if{ (>K:SPOILERS_OFF) }
	SPD_HOLD.XML: Lots of changes, most important one is removal of dependency on ALT HOLD mode
	ALT_HOLD.XML: Change from plane to indicated altitude, progressive reduction of AP vertical speed as plane is nearing target altitude
	KEYS.XML: Changes to the SPD and VS mode buttons, altitude from the alterter dial in the cockpit is now set as target altitude for these modes when ALT SEL mode is engaged
	AP_MODES.XML: NAV mode only arms if < 14nm from GPS track and captures when < 2nm from track; mods to GS capture light logic; added ALTSEL off logic; modified ALTSEL capture logic; simplified GO AROUND AP logic
	 
	 
	MDL File XML code:
	GPS CLR button mouse logic expanded (unimportant though); ALT SEL, ALT HLD, VS button mouse logic adapted to modified AP modes; cabin altitude selector mouse logic changed; Kohlsman knob,altitude reference pointer, STD button mouse logic changed(?); altitude alerter mouse logic changed; altimeter animation supports metric indication

 

 

Based on this list, the compatibility of the elements from my v2.8 mods is the following:

1. Modified SYSTEM.XML  - NOT Compatible (requires updating)

2. Autopilot modifications - NOT Compatible (requires updating)

3. Keyboard Controls - NOT Compatible (requires updating)

4. Weather radar - Compatible

5. Load/Save gauge - Compatible (requires minor updating though)

6. Low memory night lighting - Compatible

7. Callsigns - Always Compatible

8. VC Camera - Always Compatible

9. Resized Shared textures - Compatible

 

Slightly off topic, but that Falcon shot in Scott's post has me drooling.

Hi...

LOL - did you see the other Falcon posts in the forum -  Mark just posted a ton of pix on his website...
