Engine Changes

• Title screen F1 info box text can now be customized in system.def.

Tools

• Added sff2png tool: extracts sprites from an SFF file.

Engine Changes

• CNS: New Trigger: Cond. This is a short-circuiting version of ifelse.
• CNS: Set to use precise floating point model; was previously using a less accurate model that might have caused strange rounding errors.
• fight.def: Added [Fightfx] section with scale parameter.
• Keyboard: Fixed bug where keyboard presses/releases are sometimes lost when other keys are pressed at the same time.
• Storyboards: now scaled to fit screen aspect instead of being cropped.
• Stages: Added displayname, versiondate, mugenversion, author parameters to stage [Info]. Stages older than 1.0 will have camera movement snapped to whole stage coordspace units.

Doc Changes

• Added description of special forms (ifelse, cond).
• Stages + Backgrounds: Fixed Parallax parameters description to match implementation.
• Other minor fixes.

Bug Fixes

• CNS: HitDef: Fixed bug that set default guarded getpower/givepower parameters to 0.
• CNS: AppendToClipboard and DisplayToClipboard: More robust handling of type mismatch scenarios.
• CNS: Fixed bug where Const trigger returned incorrectly-scaled values if player is in a temporary state of another player with a different coordspace.

• Fixed bug where loading malformed SFFv1 sprites would prevent the program from closing properly.
• Fixed character mugenversion date parser to reject malformed version strings.

Backwards Compatibility

• ver2002 backwards compatibility: implemented bug where AssertSpecial flags that affect a single player are not reset each tick when the player is in a hitpause. Flags affected are: nostandguard, nocrouchguard, noairguard, noautoturn, noshadow, nojugglecheck, nowalk, unguardable, invisible.
• ver2002 backwards compatibility: implemented bug where the effects for the following controllers are not reset during hitpause: AngleDraw, PlayerPush, Offset, ScreenBound, Trans, Width.

Bug Fixes

• CNS: Fixed bug where hit attribute string parsing could fail in expressions.
• CNS: Fixed bug where explod's Y position is displaced if explod is created on the first tick of the round on cut stages.
• CNS: Fixed bug where DestroySelf did not abort remainder of state evaluation. This could lead to crashes or indeterminate behavior depending on the controllers used after.
• Fixed bug where pre-1.0 stages with zoffsetlink are drawn displaced by upwards 1 stage unit.

Engine Changes

• CNS: Added GameWidth and GameHeight triggers.
• CNS: Display error if character uses a controller or trigger inappropriate for its mugenversion.

Bug Fixes

• BG: Fixed bug where tiled parallax BGs did not draw.
• BG: Fixed scaled trans sub BGs.
• CNS: Fixed trigger redirection coordspace bug.
• CNS: Fixed screenpos x trigger.
• CNS: Fixed helper not inheriting palno from parent.

• FNT: Fixed font newline bug for True Type fonts with text wrapping.
• Motifs: Fixed invalid font in combo counter crash.

• Fixed AI.RandomColor = 0 crash.
• Resolved SDL crash on non-SSE2 processors.

Engine Changes

• Added high-definition (HD) graphical support.
  • Any arbitrary resolution or aspect ratio can be set. For best compatibility, we recommend using 640x480, 1280x720 or 1920x1080.
  • 1280x720 set as the new default resolution. This can be changed with the GameWidth and GameHeight parameters in mugen.cfg.
  • Characters' target resolution can be set with the localcoord parameter in the character def file. An alternative, which affects sprites only, is to set smaller xscale and yscale parameters in the constants section of a character's CNS files.
  • Stages' target resolution can also be set with the localcoord parameter in the stage def file.
  • Characters, stages and motifs made for different resolutions can still interoperate with each other.

• Added sound and text support to storyboards.
• New sprite file format: SFF v2.
  • Multiple palette support.
  • Support for realtime compressed sprites to reduce memory usage.
• New format for FNT.
  • Bitmap fonts now based on SFF v2.
  • Supports Truetype fonts.
  • UTF-8 text support (Truetype only).
  • Text can be quoted in order to use escape sequences, e.g. \n for a line break: "line1\nline2"
• CNS: New triggers.
  • AILevel: returns the AI difficulty setting.
• CNS: Added [Quotes] group to constants.
• CNS: New controllers.
  • VictoryQuote: Selects a quote for the victory screen.
• Stages: StageInfo: New parameters:
  • xscale, yscale: Specifies the drawing scale of the stage.
  • overdrawhigh, overdrawlow: Specifies the number of pixels of extra drawing beyond the top and bottom of the screen.
  • cuthigh, cutlow: Suggests the number of pixels that can be cut from the top and bottom of the screen when playing in a shorter game aspect than the stage was designed for. cutlow especially will be useful for making 4:3 stages look better when viewed in 16:9.
• Motifs: Victory screen definition can be added to system.def. See [Victory Screen] and [VictoryBG] groups.
  • Characters may use sprite 9000,2 for the victory screen.
• Motifs: system.def and fight.def font parameters standardized to take alignment and RGB color values. See font notes at end of fight.def.
• Motifs: common1.cns can now be included with motifs.
• Motifs: system.def: [VS Screen]: For consistency, changed pX.pos and pX.name.pos to pX.offset and pX.name.offset (.pos is deprecated but will still work).
• Storyboards: Added sound playback and text display capability.

Tools

• New tool: sprmake2 - Generates sff v2 files; replaces sprmaker.
  • Enhanced sprite and palette manipulation options.
• fntmaker tool deprecated; use fnt v2 def files instead.

Bug Fixes

• CNS: Fixed: HitDef P1 pausetimes expired 1 tick sooner than specified. When loading 2002.04.14 and older characters, this fix will be compensated for by subtracting 1 from the P1 pausetime after expression evaluation.
• CNS: Fixed incorrect computation results using the ** operator.
• Motifs: fight: Fixed issue where power bar anims get out of sync with each other.

Sample Content

• Added sample HD content:
  • mugen1 -- 720p motif. This is the new default motif.
  • stage0-720 -- 720p version of stage0.
• Added sample truetype font

Misc

• Base engine ported from Allegro to use SDL. There may be some minor differences, such as a change in audio volumes.

Notes

• See readme.txt for known issues.
• To update a character from 2002.04.14 to 1.0, add 1 to the value of the P1 parameter of all HitDef pausetimes. Then set mugenversion = 1.0 in the player's def file.
