in an attempt to get just the effect I want it, after numerous recompiles I decied i could write a script to stream line the process a little.
Hopefully this will be useful to some other people too.

Simply drop this script into a prim along with any textures you might want to apply to the particles.
Once its there simply type "EM" followed by a command. EM help will give you a list of commands but they are as follows:
EM go : sets the particle system going and likewise
EM stop : stops it
EM reset : resets the script to its default state
EM status : shows all the current values for the variables
EM help : help text
EM help list : list the variables and their types
EM help <variable> : list detailed help for the variable
EM dump : dump the variables to a "+" seperated list that can be saved in a note card to come back to again later.
EM dump list : to dump the list directly as a csv to be dropped into the script below.
EM upload <+ seperated list> : upload a line of variables seperated by + that you saved before.
EM <variable> : display the current value for the variable.
EM <variable> <value> : update a value with a new variable, if the emitter is on it will restart with the new value.
to use the csv list use this code clipping:
CODE
// List of variable values
list var_cont = ["8", "", "2.0", "15.0", "10.0", "NULL_KEY", "1.0", "0.1", "<1,0.5,0.1>", "<1,0.5,0.1>", "<1,1,1>", "<0,0,0>", "<0,0,-1>", "0.0", "15.0", "100", "0.15", "0.05", "<0,0,0>", "0.0"]; // replace this list with your list from the above script.
// Particle behaviour
integer glow = TRUE;
integer bounce = FALSE;
integer interpColor = TRUE;
integer interpSize = TRUE;
integer wind = TRUE;
integer followSource = TRUE;
integer followVel = TRUE;
integer flags;
updateParticles()
{
key target;
flags = 0;
if (llList2String(var_cont, 1) == "owner") target = llGetOwner();
if (llList2String(var_cont, 1) == "self") target = llGetKey();
if (llList2String(var_cont, 1) == "NULL_KEY") target = "";
if (glow) flags = flags | PSYS_PART_EMISSIVE_MASK;
if (bounce) flags = flags | PSYS_PART_BOUNCE_MASK;
if (interpColor) flags = flags | PSYS_PART_INTERP_COLOR_MASK;
if (interpSize) flags = flags | PSYS_PART_INTERP_SCALE_MASK;
if (wind) flags = flags | PSYS_PART_WIND_MASK;
if (followSource) flags = flags | PSYS_PART_FOLLOW_SRC_MASK;
if (followVel) flags = flags | PSYS_PART_FOLLOW_VELOCITY_MASK;
if (llList2String(var_cont, 1) != "NULL_KEY") flags = flags | PSYS_PART_TARGET_POS_MASK;
llParticleSystem([ PSYS_PART_MAX_AGE,(float)llList2String(var_cont,2),
PSYS_PART_FLAGS,flags,
PSYS_PART_START_COLOR,(vector)llList2String(var_cont,8),
PSYS_PART_END_COLOR,(vector)llList2String(var_cont,9),
PSYS_PART_START_SCALE,(vector)llList2String(var_cont,10),
PSYS_PART_END_SCALE,(vector)llList2String(var_cont,11),
PSYS_SRC_PATTERN,(integer)llList2String(var_cont,0),
PSYS_SRC_BURST_RATE,(float)llList2String(var_cont,13),
PSYS_SRC_ACCEL,(vector)llList2String(var_cont,12),
PSYS_SRC_BURST_PART_COUNT,(integer)llList2String(var_cont,15),
PSYS_SRC_BURST_RADIUS,(float)llList2String(var_cont,14),
PSYS_SRC_BURST_SPEED_MIN,(float)llList2String(var_cont,4),
PSYS_SRC_BURST_SPEED_MAX,(float)llList2String(var_cont,3),
PSYS_SRC_TARGET_KEY,target,
PSYS_SRC_ANGLE_BEGIN,(float)llList2String(var_cont,17),
PSYS_SRC_ANGLE_END,(float)llList2String(var_cont,16),
PSYS_SRC_OMEGA,(vector)llList2String(var_cont,18),
PSYS_SRC_MAX_AGE,(float)llList2String(var_cont,19),
PSYS_SRC_TEXTURE,llGetInventoryKey(llList2String(var_cont,5)),
PSYS_PART_START_ALPHA,(float)llList2String(var_cont,6),
PSYS_PART_END_ALPHA,(float)llList2String(var_cont,7)
]);
}
Then you simply have to call updateParticles() from your script.
Hope its not too confusing, I'm pretty sure it could be a bit cleaner, and if anyone see's anything immediately wrong feel free to correct me
.
