+    (description "bsnes-hd (called ``HD Mode 7 mod, for bsnes'' in early
+betas) is a fork of bsnes (the great SNES emulator by Near) that adds HD video
+features, such as:
+@table @asis
+@item HD Mode 7
+Renders the rotated, scaled or pseudo perspective backgrounds at
+higher resolutions.  This does not involve new custom imagery or upscaling
+algorithms.  It is a higher resolution version of the process the SNES uses.
+@item Widescreen
+Extends the scenes to the left and right, without distorting them.  It works
+for most Mode 7 scenes, but also for some other scenes/games, after some
+settings tweaking.
+@item True color
+Color calculation are done at true color instead of the SNES color depth (3x8
+instead of 3x5 bit).  With the optional line color smoothing color ``steps''
+turn into actual gradients (without influencing the sharpness of the artwork).
