Vanilla Character Select Entries

(These are all recreated examples, as they are all hardcoded in reality - see m_menu.c)

Character
SkinName = sonic
Status = 1
PlayerText = ^2Sonic^0 is the fastest of the three, but also the hardest to control. Beginners beware, but experts will find Sonic very powerful.

^2Ability:^0 Speed Thok
Double jump to zoom forward with a huge burst of speed.

^2Tip:^0 Simply letting go of forward does not slow down in SRB2. To slow down, hold the opposite direction.
#

Character
SkinName = tails
Status = 1
PlayerText = ^2Tails^0 is the most mobile of the three, but has the slowest speed. Because of his mobility, he's well-
suited to beginners.

^2Ability:^0 Fly
Double jump to start flying for a limited time. Repetitively hit the jump button to ascend.

^2Tip:^0 To quickly descend while flying, hit the spin button.
#

Character
SkinName = knuckles
Status = 1
PlayerText = ^2Knuckles^0 is well-
rounded and can destroy breakable walls simply by touching them, but he can't jump as high as the other two.

^2Ability:^0 Glide & Climb
Double jump to glide in the air as long as jump is held. Glide into a wall to climb it.

^2Tip:^0 Press spin while climbing to jump off the wall; press jump instead to jump off
and face away from
the wall.
#

Character
SkinName = sonic&tails
PicName = CHRS&T
Status = 1
PlayerText = ^2Sonic & Tails^0 team up to take on Dr. Eggman!
Control Sonic while Tails desperately struggles to keep up.

Player 2 can control Tails directly by setting the controls in the options menu.
Tails's directional controls are relative to Player 1's camera.

Tails can pick up Sonic while flying and carry him around.

Game modifying commands/variables

All console commands/variables that actually set off the "game has been modified" trigger directly; most cheats do not fall in this category as they depend entirely on development mode being enabled to have any effect at all (by which time the game has already been modified)

Commands

addfile
runsoc
map (if -force used)
devmode
god
noclip

Understanding bitwise operators

Let's use Object flags constants to help explain things here...

bitwise AND (`&`)

example value: mobj.flags = MF_SPECIAL|MF_ENEMY|MF_SHOOTABLE|MF_NOGRAVITY|MF_SLIDEME

In binary, mobj.flags has a value of 10000000000101000000101

This makes more sense if we turn this sideways, and place the object flags by their corresponding bits:

MF_SPECIAL         1
MF_SOLID           0
MF_SHOOTABLE       1
MF_NOSECTOR        0
MF_NOBLOCKMAP      0
MF_AMBUSH          0
MF_PUSHABLE        0
MF_BOSS            0
MF_SPAWNCEILING    0
MF_NOGRAVITY       1
MF_AMBIENT         0
MF_SLIDEME         1
MF_NOCLIP          0
MF_FLOAT           0
MF_BOXICON         0
MF_MISSILE         0
MF_SPRING          0
MF_BOUNCE          0
MF_MONITOR         0
MF_NOTHINK         0
MF_FIRE            0
MF_NOCLIPHEIGHT    0
MF_ENEMY           1
MF_SCENERY         0
MF_PAIN            0
MF_STICKY          0
MF_NIGHTSITEM      0
MF_NOCLIPTHING     0
MF_GRENADEBOUNCE   0
MF_RUNSPAWNFUNC    0

let's say we want to check if mobj.flags has MF_ENEMY or not

so typically we use "mobj.flags & MF_ENEMY" to do this

since we already know mobj.flags has MF_ENEMY, this means mobj.flags & MF_ENEMY actually gives us the value of MF_ENEMY!

why does it do this, you wonder? see, what "mobj.flags & MF_ENEMY" actually does in terms of binary is the following:

               mobj.flags    &   MF_ENEMY    ->      result

MF_SPECIAL         1                 0                 0
MF_SOLID           0                 0                 0

MF_NOSECTOR        0                 0                 0

MF_RUNSPAWNFUNC    0                 0                 0

MF_ENEMY only turns on one bit, and since mobj.flags has that bit, the whole operation results in only the value of that bit

if mobj.flags DIDN'T have a particular flag, say for instance we did "mobj.flags & MF_BOUNCE", the result would be 0:

               mobj.flags    &   MF_BOUNCE   ->      result

here the result is the value of MF_NOGRAVITY and MF_SLIDEME combined, since they were BOTH present in mobj.flags

here's another example, "mobj.flags & (MF_SHOOTABLE|MF_MISSILE)". This gives the following:

mobj.flags has MF_SHOOTABLE but NOT MF_MISSILE, so the result gives only the value of MF_SHOOTABLE

this is very important to note, as this means when using & with multiple flags, the result differs depending on which of flags are present in mobj.flags

Real version numbers

From Demo 1 to the Final Demo releases a different versioning system was in place to what the SRB2 versions were released as to the public. Until v1.08 these versions were displayed on the title bar of the SRB2 window (if playing in windowed mode):

Version name	Real version number
Demo 1	v0.25
Demo 2	v0.5
Demo 3	v0.6
Demo 4 to 4.1	v0.6
Demo 4.35	v0.65
SRB2 2k3	v0.70
v1.01 to v1.04	v0.70
v1.08	v0.70? (from source code)
v1.09 to v1.09.4	unknown

From 2.0 onwards this different versioning system was discarded in favour of the current 2.X version numbers, while the Demo and Final Demo versions were retroactively designated as 0.X and 1.X.

Video flags bit layout table

Was thinking of dumping this thing in the bits/masks section of Video flags, though wasn't sure entirely. The "0"s just represent a bit, and are color-coded corresponding to the section to look pretty. All the "Bit" columns are 2em wide to make everything look even too! \o/

Bit	31	30	29	28	27	26	25	24	23	22	21	20	19	18	17	16	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1	0
Section	Misc.												Alpha				Color				Spacing		Scale		Param
	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`	`0`

Player start fallback order

Gametype	Single Player/Coop Race/Competition Tag/Hide & Seek ("it" players)	Match/Team Match CTF (spectators only) Tag/Hide & Seek (non-"it" players)	CTF (non-spectators)
1.	Player 1 - 32 Starts	Match Start	CTF Red Team Start (Red team) CTF Blue Team Start (Blue team)
2.	Match Start	CTF Red Team Start or CTF Blue Team Start (random choice)	Match Start
3.	CTF Red Team Start or CTF Blue Team Start (random choice)	Player 1 - 32 Starts	Player 1 - 32 Starts
4.	Spawn at first Thing placed in map	Spawn at first Thing placed in map	Spawn at first Thing placed in map
5.	Spawn at coordinates (0,0)	Spawn at coordinates (0,0)	Spawn at coordinates (0,0)

Screen fade red to alpha algorithm

Probably not needed for screen fade, but it may be interesting for some people to know anyway.

The algorithm to calculate the translucency of a color in a fading mask:

x: The level of red present in the color, represented as an integer between 0 and 255.
m: (11*(x + 1) / 257), rounded down to the nearest full integer. This should be a value between 0 and 10, where 0 is invisible and 10 is opaque.
p: The percentage of translucency. This is determined by ((10 - m) * 10%).

Example: a red level of 255

x = 255

m = 11*(255 + 1) / 257 = (11*256) / 257 = 2816 / 257 = 10.[...]

p = (10 - 10) * 10% = 0 * 10% = 0%

255 → 0%

Possible listings for lost level contests

Transcendental Fort Zone and Tets Base Zone were listed in the "Level of the Month" section of the old Addons site, for winners of the level contests: [2] Going by their dates they were likely the winners of July and August 2003 respectively.

They also appear in this list with a bunch of other levels: [3] Interestingly, the entire Match divisions of September 2003 onwards are also included here.

Here are the levels I know or guess to be from these unrecorded OLDCs so far:

(Note, both have only a Match division)

July 2003

Snow Hill Zone by Tets (probably confirmed? [4])
Blue Sky Zone by Tets (???)
Vacant Rocketship Zone by Digiku (confirmed: [5])
Transcendental Fort Zone by a441 (confirmed winner: [6])

August 2003

Note: a news post confirms that in September 24th 2003, 4 new "Battle" stages were added from "last month's contest": [7]

Nitric Nexus Zone by a441 (???)
Tets Base Zone by Tets (confirmed winner: [8])
Green Hill DM Zone by JTE (confirmed: [9])
Waterfall Island Zone by Digiku (confirmed: [10])

SRB2 World contests

These were unofficial contests hosted by a441 at one point. Several levels included in the game in v1.08 were apparently entered in the second of these contests originally!

Here's the levels I know of that were entered in these contests. A source for some levels and map numbers is [11]

UPDATE (30/07/17): I FOUND THE ACTUAL WADS FOR THESE CONTESTS

Contest 1: GFZ Battle

In this contest, the entrants were asked to design a multiplayer level that works in the Match and Tag modes. Maps were limited to using a selection of GFZ textures and thing types (see Announcement and Rules: [12])

Dates: May 16th (?) - June 30th 2003 (original deadline was June 8th, but was extended)

MAP01 - GFZ Battle Zone Act 1, by ???
MAP02 - GFZ Battle Zone Act 2, by a441 - later released as Paragon Valley Zone
MAP03 - GFZ Battle Zone Act 3, by ???
MAP04 - GFZ Battle Zone Act 4, by ???
MAP05 - GFZ Battle Zone Act 5, by a441 - was later modified significantly and released as Stone Quadrant Zone

Included bonus levels:

MAP06 - GFZ Battle Zone Act 6, by Mystic - later became Sapphire Falls Zone (was disqualified)
MAP07 - Two D Battle Zone, by a441

Contest 2: Capture the Flag

In this contest, the entrants were asked to design a CTF level:

MAP01 - Iron Warehouse Zone by msonic [13]
MAP02 - Stone Walkway Zone by a441 (author source: [14])
MAP03 - Dueling Peaks Zone by FuriousFox [15]
MAP04 - Twin Hills Zone by a441 [16]
