----------------------------------------------------------------------------------------------------------------------------------------------------
|
||||
|
||||
* you can now switch between FM cores without reseting the game. FM registers value are automatically restored when switching.
|
||||
* removed the previous VINT timings modification because it brokes some games (Rocket Knight, Thunderforce III,...)
|
||||
* added automatic Timing configuration (VDP latency, VINT timing & alternate Line Timing) at game loading, based upon specific romname detection.
|
||||
This means you can still modify some of these options afterwards but they are now automatically set/unset when loading a game which need
|
||||
special timing fixes. These fixes are also automatically desactivated when the current game doesn't need them.
|
||||
For information, games that are actually detected and need special timings to run properly are:
|
||||
.Legend of Galahad & Road Rash series (single line not rendered properly)
|
||||
.Sesame Street Counting Cafe (don't boot)
|
||||
.Chaos Engine/Soldiers of Fortune (graphic glitches on scrolling)

DISCLAIMER:
|

|

THIS IS A VERY BASIC & UNSTABLE PORT WHICH ONLY PURPOSE
|

IS TO SHOW HOW TO USE GENESIS PLUS GX CORE & INTERFACE IT
|

WITH SDL2 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.

||||
|
||||
|
||||
Controls
|
||||
-----
|
||||
|
||||
Arrow Keys - Directional pad
|
||||
A/Q,S,D,F - buttons A, B(1), C(2), START
|
||||
W,X,C,V - buttons X, Y, Z, MODE if 6-buttons controller is enabled
|
||||
Tab - Hard Reset
|
||||
Esc - Exit program
|
||||
|
||||
F2 - Toggle Fullscreen/Windowed mode
|
||||
F4 - Toggle Audio (Turbo mode must be disabled first)
|
||||
F6 - Toggle Turbo mode (Audio must be disabled first)
|
||||
F7 - Load Savestate (game.gpz)
|
||||
F8 - Save Savestate (game.gpz)
|
||||
F9 - Toggle VDP mode: PAL(50hz)/NTSC(60hz)
|
||||
F10 - Soft Reset
|
||||
F11 - Toggle Border emulation
