I am thinking that Species specific skills ie Yaz battle rage, Dralasite lie detection etc should be done as a skill 10%/level + 1/2 ability score. This means out of the gate players will be using the species abilities without it being a joke at 5% ( Remember the idea here is that this is a stripped down rule set for use at a convention). It is then treated as a In PSA skill to improve. Lie detection tests with LOG, Battle rage with PER and Comprehension with INT. 

Unified Field Theory- all defensive screens work the exact same way 1 SEU to ablate 5 pts of damage from the appropriate damage type 

Holo screen obviously works differently 

Unified ranges- I think that the range bans are really about a character's ability to see, aim and shoot; not about the capability of the weapon so what if all ranges werre the same? PB is 0-2 meters for all weapons, short is w-x, medium is y-z, long range is beyond medium and a weapon simply has a max range stat. There has been almost no shooting at long range in any of my games over the last 2 years and most combats are point blank to short. 

strip down the combat modifiers for shooting and mele- there are a lot of them and most people ignore half of them until they are looking for an advantage and invoke defending or careful aim. 

Players want to fly the millenium falcon so spacer skills have to be dumbed down. no high prerequisites. 

I'm currently uisng the Spacer Skills revisited rules from SFMAn #10 or 11 but only for gaining a 1st level skill - after that no progressive prerequisites just advance the spacer skill as you like. 

I have a better idea.

In the past I was giving a deck of magic items and i kind of thought is was of little use to me. But at a con game if you had said deck of magic items I would just hand out the card. to the player and move on with the game. No five minute slow downs. 

Star Frontiers doesn't have "magic items" per se but you can do this with an index card and loot item discovered or special weapon etc. just hand them out. and keep the game moving. 

stripped down simplified Character creation PS is included here instead of something you have to search the book for

One paragraph to sum up a species and then their ability mods and racial abilities, their movement

combat modifiers cut down by half for melee and shooting

Skill checks are a straight 10%/level + 1/2ability score Subskills might have a bonus or negative in their description to account for some things being easier or harder

Character sheets

Sub skill actions on the back of the character sheet. Not a full description but just a quick reference

S&W Light used equipment packages where you chose one of two. We have the standard equipment pack of the basic game that can be automatic and then a choice of one of two equipment options. weapons and defenses are issued per the scenario or game master 

Been a while since i looked at it. the thing is, as I remember is, the basic game lacks skills? and I want to approximate a full SF game experience.

However you do ask a good question and I should probably take a second look at the Basic Plus project

Canon Basic lacks skills. Basic Plus doesn't have skills per se, although it does introduce Primary Skill Areas which allow bonuses to the particular actions in that field.
