      Short: Amiga emulator with PPC JIT and ReAction GUI
Author: Richard Drummond, Almos Rajnai, Kjetil Hvalstrand, Falke_34 et al.
Uploader: Falke_34
Type: emulation/amiga
Version: 2.0 (ReAction GUI 1.0, based on E-UAE PPC JIT 1.1.2)
Requires: AmigaOS 4.1 Final Edition, AHI, Kickstart ROM image
Architecture: ppc-amigaos >= 4.1.0
License: GPL
E-UAE ReAction
==============
E-UAE is an emulator of the Commodore Amiga for AmigaOS 4.1 PPC, with a
just-in-time compiler for 68020+ code (PowerPC JIT by Almos Rajnai). This
release adds a native ReAction configuration GUI and many fixes and new
features to the AmigaOS 4 version of E-UAE.
E-UAE 2.0.0 with ReAction GUI 1.0 (internal build v17).
It runs on all AmigaOS 4.1 PPC systems (AmigaOne X5000/X1000/A1222,
Sam440/460, Pegasos II, Classic PPC) and under QEMU.
Highlights
----------
* ReAction GUI with pages for media, hardware, display, sound, hard
disks, input, shortcuts and configuration; tooltips; English and German
(locale catalog)
* PowerPC JIT compiler, 68000 - 68060, FPU, AGA, Zorro II/III memory
* Built-in Picasso96 graphics card (uaegfx.card in the boot ROM, up to
128 MB, hardware mouse pointer, VBLANK interrupt)
* Hard disks: directories, hardfiles (with RDB), IDE controller of the
A600/A1200 (Gayle) and A4000
* CD-ROM drive with ISO and CUE/BIN images (also CD audio), at
uaescsi.device or as ATAPI drive at the IDE controller; bootable as CD0:
with any Kickstart
* Amiga CD32: Akiko chip from WinUAE (CD-ROM controller with CD audio,
chunky-to-planar converter, NVRAM for game saves), CD32 pad, CD32
model preset
* Disk images also inside ZIP, GZ, LHA and LZX archives
* Create blank floppy disks and hardfiles from the GUI
* Configurable hotkeys, savestates, bsdsocket.library emulation
Installation
------------
Copy the drawer anywhere and start E-UAE from its icon. Put your Kickstart
ROM images into PROGDIR:Roms/ (or choose another folder in Settings).
Kickstart ROMs are NOT included - they are copyrighted. Use the ROMs from
Amiga Forever or dump them from your own Amiga. The CD32 needs its
Kickstart and extended ROM (two 512 KB files, or one 1 MB CD32 ROM).
For the graphics card the emulated Amiga needs Picasso96 (rtg.library) and
the monitor file DEVS:Monitors/UAEGFX; the uaegfx.card itself is built in.
Usage notes
-----------
* Right mouse button menu of the GUI window: About, Settings, Quit.
* Settings: default folders for ROMs, floppies, hardfiles, CD images,
configurations and savestates, and the log output (off / window /
file PROGDIR:E-UAE.log). Saved in PROGDIR:E-UAE.prefs.
* "Save" writes the default configuration, "Save as..." any file
(".cfg" is added).
* CD-ROM: Hard disks page -> "Add CD-ROM drive...". To boot from CD tick
"Boot from CD (mount as CD0:)". Without that option the emulated Amiga
needs a CD file system (CDFileSystem, CacheCDFS, ...) and a mount entry;
at uaescsi.device: Device = uaescsi.device, Unit = 0, SectorSize = 2048.
The ATAPI drive at IDE needs a scsi.device with ATAPI support
(Kickstart 3.1.4 / 3.2 or a patched driver). A CD drive alone on the
slave position (no master) delays the boot by about 30 seconds, like
on real hardware.
* CD32: Hardware page -> model preset "CD32 (AGA, 2 MB, Akiko)". On the
Media page choose the CD32 Kickstart and extended ROM (or the 1 MB
CD32 ROM as Kickstart, extended ROM empty) and the CD image (ISO or
CUE/BIN). Discs can be changed while the CD32 runs. Game saves go to
PROGDIR:cd32.nvr. The joystick in port 1 is a CD32 pad: buttons 1-7 =
red, blue, yellow, green, forward, reverse, play.
* Default hotkeys: Ctrl + Alt + Q quit, Ctrl + Alt + S fullscreen,
Ctrl + Alt + R reset, Ctrl + Alt + F1..F4 insert disk in DF0..DF3 -
all can be changed on the Shortcuts page.
History
-------
v17 (E-UAE 2.0.0, ReAction GUI 1.0)
Core:
- Amiga CD32: Akiko chip ported from WinUAE - CD-ROM controller (data,
CD audio, sub-channel, disc change), chunky-to-planar converter,
1 KB NVRAM, CD32 pad
- CD32 ROMs: Kickstart + extended ROM, also the 1 MB CD32 ROM in one
file
- LHA/LZH and LZX archives opened directly (disk images, ROMs)
GUI:
- CD32 model preset, "CD32 Akiko chip" switch, CD controller
"CD32 (Akiko)"
- Window stays open after Stop; model presets switch the IDE
interface on like real hardware; options without effect on
AmigaOS 4 removed
- GUI can be iconified (gadget, optional automatically after Start)
- Middle mouse button releases the pointer in window mode (option)
- Cartridge field (Action Replay, HRTMon) on the Media page
Fixes:
- "Save" while running saved the running values; backup file only
made once
- Kickstart field showed "kick.rom" at the first start
- uaescsi.device (CD-ROM) was missing after Stop and a new Start
- Colours yellow after switching to fullscreen and back
- 48000 Hz sound silently became 22000 Hz
- bsdsocket.library emulation: crashes (e.g. WHDLoad update check),
emulation froze during network calls, several wrong calls
- Fix: start from the Workbench icon
v16
Core:
- Built-in uaegfx.card (no card file needed), hardware mouse pointer,
VBLANK interrupt, BlitRectTransparent
- Graphics card memory up to 128 MB (16/32 MB boards were announced as
8 MB before)
- Faster RTG output: changed lines copied once per frame, window only
redrawn when something changed
- CD-ROM drive with ISO and CUE/BIN images, CD audio, disc change while
running; at uaescsi.device or as ATAPI drive at the IDE controller
- Booting from CD: built-in ISO 9660 file system, drive mounted as CD0:
- uaescsi.device fixes (unit thread end, request abort, repeated
installation in the boot ROM area)
GUI:
- Real fullscreen switches for Amiga and Picasso96 modes, fullscreen
hotkey toggles window / own screen
- Graphics card options (hardware pointer, VBLANK)
- CD-ROM drive on the Hard disks and Media pages
- Menu (About, Settings, Quit) and Settings window (folders, log output)
Fixes:
- Grey screen left after quitting from an own screen
- Status bar showed "CPU 0%" at full load
v15
Core:
- JIT soft cache flush (keeps unchanged translated code)
- JIT is switched off when cycle-exact is enabled (as in WinUAE)
- Display was composited twice per frame - up to 8x faster with JIT
at maximum CPU speed
GUI:
- CPU list with 68020/68881 FPU combinations (FPU was silently removed)
- Create blank floppy disks and hardfiles (OFS/FFS, PFS3, SFS, RDB)
- Hard disks page redesigned: one drive list, separate windows for
hardfiles and directories
Fixes:
- "Load..." did not load the configuration
- Model preset recognised after loading
- Hotkeys checked the wrong keys (Alt vs. Amiga key), modifier order,
stuck keys
- "Save as..." adds ".cfg"
v14
- Hard disks: RDB hardfiles can be added, one list for UAE and IDE drives
v12 - v13
- IDE controller emulation: A600/A1200 (Gayle) and A4000, master/slave
v11
- CPU core: exception frames and undefined flags of CHK, CHK2, DIVL,
MULL fixed (checked with the UAE CPU tester)
v10
- CPU/FPU core fixes (DIVS.W overflow, FPU rounding, FABS, FSCALE, FCMP,
FGETEXP, FTRAPcc, FMOVECR constants)
- Shortcuts page: hotkeys can be reassigned
- LED overlay in 16-bit screen modes
v1 - v9
- ReAction GUI, tooltips, locale support (English, German)
- Amiga model presets, JIT cache size choice
- Fixes: wrong colours, 100% host CPU load while waiting, crash in
path handling, empty window without hardware compositing, 68040/68060
32-bit only, quitting from the start screen
