Ok that one worked.
Like I said, if you want to get your sprites to look right open your wad in XWE with 1.09.4's srb2.srb and export them, then change to 2.0 (or 2.1)'s srb2.srb and reimport them, that will fix the colors.
And to play your levels in coop on this line in your maincfg:
typeoflevel = 4097
Replace that 4097 with the word Coop.
Ok and now for some issues I noticed.
When adding the file I got a bunch of errors over your soc, namely this one:
Thing 3
Speed = 10
Damage = 5
SPAWNHEALTH = 50
Thing 6
Speed = 40
Damage = 5
SPAWNHEALTH = 100
Thing 9
Speed = 40
Damage = 5
SPAWNHEALTH = 100
That's probably because when you're writing for objects you need to have all of the values listed, even if you're not using them:
Thing
MAPTHINGNUM =
SPAWNSTATE =
SPAWNHEALTH =
SEESTATE =
SEESOUND =
REACTIONTIME =
ATTACKSOUND =
PAINSTATE =
PAINCHANCE =
PAINSOUND =
MELEESTATE =
MISSILESTATE =
DEATHSTATE =
DEATHSOUND =
XDEATHSTATE =
SPEED =
RADIUS =
HEIGHT =
MASS =
DAMAGE =
ACTIVESOUND =
RAISESTATE =
FLAGS =
The other thing I noticed were your scripts. They had names like A, B, and C. Scripts to be used in levels need to have a name like scrxx0000 where xx is the map number and 0000 is a number that a linedef can be used to identify. An example would be scr010001.
Yeah, I know there's a lot of information, but it can be figured out if you're patient. ^^;
