Changes in version 0.9.0 (15.07.2016)

    • Added support for the 68030. (4 instructions)
    • Exploded each instruction to it's own size-form and sometimes additionally to it's type form.
    • For faster access, each instruction does now have it's customized parameter-object.
    • Effective-address access and decoding are now done via 6+1 highspeed function-tables, each 64 entries long.
      This does save up to 12 (3*2*2) switch statements per instruction.
    • Condition-code checking is now done via a 16 entries long function-table instead of a switch-function with 16 entries.
    • Optimized condition-code calculations.
    • Fixed/removed DIVU-remainder calculation, also new and faster DIVS.
    • New and faster versions of ABCD, NBCD, SBCD, ASL, ASR, LSL, LSR, ROL, ROXL, ROR, ROXR.
    • Fixed MOVEP instruction.
    • Fixed all 68000/68010 execution-time calculations.
    • Program-counter calculations are not hardcoded any more.
    • Ported high-level functions from actual WinUAE.
  • General
    • Re-ported and optimized the following parts from actual WinUAE:
      Audio, Blitter, CIA, Config, Copper, CPU-highlevel, Custom, Disk, Drawing, Events,
      Expansion, Filesys, Gayle, Hardfile, IDE, Memory, Roms, Playfield, RTC and Serial
  • Chipset
    • Custom-chip registers are now accessed via a 256 entries long function-table instead of a switch-function with 256 entries.

    • Access is now done via function-tables (banks) instead of area-selecting switch-functions.
  • ROM
    • Added support for encrypted Cloanto-roms. (Amiga Forever)
    • Added special A1000 kickstart handling.

    • Many new options. Not listed here, see sae/config.js for details.
  • API
    • Deprecated and removed the old API function "SAE()". We're on javascript, so let's use: (new API)
      "var sae = new ScriptedAmigaEmulator(); [...] var error = sae.start(); [...]" See index.js for details.
    • Reworked error-handling for API-calls. Now an error-code (SAEE_*) is returned on any API-call.
  • Common
    • Introduced global functions, references, variables and constants for more speed. See sae/amiga.js for details.
    • Moved all entries from constants.js to their specific place and renamed them to match the new global name-space.
