  Source code for the GPL/LGPL parts above: the complete corresponding
  source code is distributed alongside this release as
      RGen-1.0.0-compiler-sources.zip
  (the compiler is unchanged since 1.0.0, so that file applies to 1.1.0)
  It contains the exact upstream source archives of GCC 14.2.0, GNU Binutils
  2.43.1, GMP 6.3.0, MPFR 4.2.1, MPC 1.3.1, GNU libiconv 1.17, gettext 0.22.5
  and MinGW-w64 12.0.0, plus the WinLibs build recipes. Those recipes contain
  the small build patches WinLibs applies. SOURCES.txt inside lists the
  versions, upstream URLs and SHA-256 checksums.

  Written offer: for at least three years after we last distribute this
  release, we will give anyone who asks a copy of that complete corresponding
  source code on a common data medium (or by download), for no more than our
  cost of physically performing the distribution. Contact:
      sales@arcadegamecave.com

Prior art / credit (no code or data used)
  The Sonic the Hedgehog 2 widescreen mode follows the approach of the
  "Sonic 2 Community's Cut" / "Sonic 2 Widescreen Hack" by heyjoeway
  (github.com/heyjoeway/s2disasm, archived; continued as
  github.com/Hitaxas/Sonic-2-Communitys-Cut), built on the Sonic Retro
  s2disasm, and heyjoeway's Genesis Plus GX fork: a wider render, a widened
  sprite cull and a widened ring window. Thanks to its authors for the idea.
  No code or data from those projects is included in RGen; RGen applies its
  own small hooks to your unmodified ROM at build/run time.

Nothing in this package is derived from any game ROM. No ROMs are included.
