+z26v3 (an Atari 2600 emulator)
+
+Z26 is one of the best emulators for the Atari 2600. The author reports
+that the graphics part of the emulator is nearing perfection to a point
+that there's little more to fix.
+
+This is z26 version 3.x, which may have some issues running on Linux
+(depending on your hardware & config), and the authors aren't interested
+in fixing them. If you have problems you can't solve, try the older 2.13
+release, by installing games/z26 (which won't conflict with this build;
+you can have both installed).
+
+Specific Linux issues in this version:
+
+- The config file (z26.gui) is always read & written in the directory
+  where the ROM image is located. If the file doesn't exist and z26 can't
+  write to the directory, it refuses to start. This means no root-owned,
+  system-wide /usr/share/games/roms/2600 directory (even if users can
+  write there, they'll overwrite each others' config files).
+
+- The video timing relies on OpenGL VSync. If your card/driver combo is
+  incapable of this, the games will run insanely fast. Even with VSync
+  support, the games run at whatever your monitor refresh rate is set to
+  (for LCD panels this is usually 60Hz, which is correct for NTSC games).

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.

+# Possibly TODO: write a man page. Upstream didn't bother to document
+# the command line options (even went so far as to remove the man page
+# and usage message that used to be in z26 2.x). The options have changed
+# since 2.x, so it would be a tedious process of reading the source code.
+# Not in the mood right now, maybe later.
+
+# Also possibly TODO: a patch to keep the config files (z26.gui and
+# z26.cli) in the user's home directory instead of whatever dir the
+# ROM file happens to live in. Leaving it as-is has its uses: different
+# sets of ROMs might require different options, so you could separate
+# them into dirs and each dir gets its own config file. Maybe the patch
+# should leave the config file locations alone, but allow the emulator
+# to start in the absence of a config file. Still thinking on this one.
