libsdl1.2debian 1.2.64-5 (i386 binary) in ubuntu mantic

 This package contains sdl12-compat, a binary compatible API for programs built
 against SDL 1.2, but using SDL 2.0.
 .
 This package replaces the classic SDL 1.2 library with the SDL 2.0
 compatibility layer, so that all SDL 1.2 program will use it.
 .
 If you are writing new code, please target SDL 2.0 directly instead
 of using this layer.
