// Compatibility flags are controlled by assets/compat.ini.
|
|
// Alternatively, if PSP/SYSTEM/compat.ini exists, it is merged on top, to enable editing
|
|
// the file on Android for tests.
|
|
//
|
|
// This file is not meant to be user-editable, although is kept as a separate ini
|
|
// file instead of compiled into the code for debugging purposes.
|
|
//
|
|
// The uses cases are strict:
|
|
// * Enable fixes for things we can't reasonably emulate without completely ruining
|
|
// performance for other games, such as the screen copies in Dangan Ronpa
|
|
// * Disabling accuracy features like 16-bit depth rounding, when we can't seem to
|
|
// implement them at all in a 100% compatible way
|
|
// * Emergency game-specific compatibility fixes before releases, such as the GTA
|
|
// music problem where every attempted fix has reduced compatibility with other games
|
|
// * Enable "unsafe" performance optimizations that some games can tolerate and
|
|
// others cannot. We do not currently have any of those.
|
|
//
|
|
// This functionality should NOT be used for any of the following:
|
|
// * Cheats
|
|
// * Fun hacks, like enlarged heads or whatever
|
|
// * Fixing general compatibility issues. First try to find a general solution. Try hard.
|
|
//
|
|
// We already have the Action Replay-based cheat system for such use cases.
