|
||
* 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)
