DISCLAIMER:
|
||
|
||
THIS IS A VERY BASIC & UNSTABLE PORT WHICH ONLY PURPOSE
|
||
IS TO SHOW HOW TO USE GENESIS PLUS GX CORE & INTERFACE IT
|
||
WITH SDL IN PARTICULAR. BUILDS ARE NOT MEANT TO BE REALLY
|
||
USED FOR ANYTHING ELSE BUT EASIER CORE DEBUGGING ON WINDOWS.
|
||
PLEASE DO NOT DISTRIBUTE WIN32 BINARIES WITHOUT THIS NOTICE.
|
||
END USERS SHOULD PREFERABLY USE LIBRETRO PORT WITH RETROARCH.
