About installation and uninstallation
There is no need to install it. Simply extract the compressed file to a suitable folder.
Uninstalling simply deletes the deployment folder.
The registry is not used.
About BIOS file
The BIOS needs to be extracted out of the actual machine.
Saves addresses 00000000 to 0007FFFF from Pro Action Replay that can be connected to a PC.
The file name is arbitrary.
It works without BIOS, but compatibility is lost.
About backup RAM
When a new backup RAM file (InternalBackupRAM.bin or ExternalBackupRAM.bin) is created, the backup RAM is uninitialized.
Initialize on the saved data management screen.
If you do not initialize, you may not be able to save in the game.
If there is no BIOS, there is no need to initialize.
About the configuration file
The first launch game uses SSF.ini settings.
So SSF.ini is the default value.
SSF.ini can be set when starting with no disk. Setting.ini is a preset.
The settings of the game once started are saved in the Setting folder (settings are saved for each game).
The setting does not change even if you replace it with a different game during startup.
SSF.ini and Setting.ini do not guarantee compatibility between versions.
Items and setting values may change.
Moreover, since it is a text file, it can be rewritten directly.
As a function that cannot be set in the options dialog,
Change [Program1]-> DisableInput to 0-Accept input even when window has no focus
[Program4]-> 68000Type changed to 1-white saturn (reproduces bugs such as initial outrun, space harrier)
Change [Program4]-> ShowRegister to 1-Display SH2,68000, SCU-DSP, SCSP slot register values [SSFV]-for recording
[Other]-> DateFlag is changed to 0-The internal clock of Saturn is not set (Time setting screen is displayed. Only with BIOS)
If there is no BIOS, it will remain 0 even if it is executed, but some software will not work unless it is changed to 1.
[Input]-> VariableRapid-Variable firing width of each terminal and port (variable at + n / 60 seconds at random)
And so on.
Keyboard or pad can be used.

Ron = Z key (Mahjong Panel)
The 2P side is not keyed by default. You can use it after setting the key.
Do not check the Scanline Base Timing option when recording in a single-core environment.
If Shift is pressed immediately after starting SSF, it switches to ST-V.
Similarly, pressing Space will temporarily reduce 1Block Clock to 60%.
Similarly, if Ctrl is pressed, BIOS use ON / OFF is temporarily switched.
Similarly, if you hold down the Alt key, GPU rendering will be turned ON / OFF temporarily.
Similarly, when Tab is pressed, ON / OFF of the object cache is temporarily switched.
Similarly, pressing 1 to 5 switches the setting (corresponds to [Setting1] to [Setting5] in the Setting.ini file).
Description of options
