There aren't any updates to Rollcall beyond what's available on the site. The updates that I did make were messy hacks and the updates I was trying to make were just getting worse. It was very much designed for Warhammer 4th Edition and so making it work with later editions is very tricky.
As for special weapons (I'm assuming you're talking about Space Marine Devastators being able to take up to four weapons from a selection, for example) the only way that Rollcall lets you do it is to duplicate things and give them the same mutex (mutual exclusion) group. Here's what the Rollcall file has for the 40K 3rd edition Marines:
- Code: Select all
[Unit501]
UnitID=501
Name=Devastator Squad
...
EquipmentA=1,1,Power Armour,0,1,1,4
EquipmentB=2,0,Bolter,0,0,0,0
EquipmentC=3,0,Sergeant Bolt Pistol + CC Weapon,0,0,3,0
EquipmentD=4,0,Missile launcher,=20,0,4,0
EquipmentE=5,0,Missile launcher,=20,0,5,0
EquipmentF=6,0,Missile launcher,=20,0,6,0
EquipmentG=7,0,Missile launcher,=20,0,7,0
EquipmentH=8,0,Heavy bolter,=15,0,4,0
EquipmentI=9,0,Heavy bolter,=15,0,5,0
EquipmentJ=10,0,Heavy bolter,=15,0,6,0
EquipmentK=11,0,Heavy bolter,=15,0,7,0
EquipmentL=12,0,Lascannon,=35,0,4,0
EquipmentM=13,0,Lascannon,=35,0,5,0
EquipmentN=14,0,Lascannon,=35,0,6,0
EquipmentO=15,0,Lascannon,=35,0,7,0
EquipmentP=16,0,Plasma Cannon,=35,0,4,0
EquipmentQ=17,0,Plasma Cannon,=35,0,5,0
EquipmentR=18,0,Plasma Cannon,=35,0,6,0
EquipmentS=19,0,Plasma Cannon,=35,0,7,0
EquipmentT=20,0,Multi-melta,=35,0,4,0
EquipmentU=21,0,Multi-melta,=35,0,5,0
EquipmentV=22,0,Multi-melta,=35,0,6,0
EquipmentW=23,0,Multi-Melta,=35,0,7,0
The price (first item after the name) is =# for a single cost item, then the mutex is 4, 5, 6 or 7. It's ugly and it'll show a big list of 20 weapons at first, then 16 when you select one, then twelve and so on, but that's the only way I ever found to do it in Rollcall.
