Unreal (1998) ported to run natively on AmigaOS4

This is an unofficial, non-commercial fan port - it is not
affiliated with, endorsed by, or sponsored by Epic Games -
Unreal, the Unreal Engine, and all related assets are the
property of Epic Games.

This archive does NOT contain any original Unreal game data
(textures, maps, sounds, etc) - you need your own legally
obtained copy of Unreal to use this port - this port itself
is not sold; optional donations are welcome but never
required - that said, donations genuinely make a difference
in whether future projects like this one happen at all
Shared for preservation and hobbyist interest only.

Based on the open community source fork:
https://github.com/fgsfdsfgs/UE1

Installation:

Run the "Install" icon in this drawer (uses the official
AmigaOS4 Installation Utility) - it will ask for the root folder
of your original Unreal CD or mounted ISO and copy the required
game data into place automatically

Changes in this version (1.2):

Fixed fullscreen mode not saving/restoring correctly
Rebuilt the installer with the official AmigaOS4
Installation Utility; manual copying also supported now
Package layout now matches the original game (System
drawer holds engine files, data drawers at the root)
Fixed big-endian package loading
Static linking of driver packages (NSDLDrv, NOpenALDrv, etc)
Rewritten threading support for stable audio
Various rendering fixes
Build optimization pass (O3 + LTO)

Known issues:

Fullscreen at exactly your desktop resolution may open
behind Workbench on some systems - this appears to be
system-specific: it has been confirmed working fine on
other AmigaOS4 machines - if it happens to you, using a
different resolution than your desktop resolution avoids
it for now
Lighting driver bug in the GLES2 renderer: FPS occasionally
drops to around 30 in scenes with many light effects

Tested exclusively on:

AmigaOne X5000 with Radeon RX580
Average ~60 FPS, dropping to ~30 FPS in scenes with heavy
lighting (see known issues above)
Feedback and bug reports welcome via the Amigans.net thread
linked above
