Windows 98 resurrection plan (7): DOSBox Pure real-time save, detailed explanation of rewind function, auto-loading game utilization technique | T Kebang

Benefiting from being the core of the emulator under RetroArch, DOSBox Pure also supports real-time save and rewind functions. Let us take a look at how to use it.

No longer afraid of operating mistakes

I believe that many people will use the real-time save and rewind function to overcome many difficult challenges when playing the emulator. The former can create a save point at any time and read it immediately when the operation is wrong, while the latter can rewind like a movie. The belt is the same, going back directly to the previous point in time, so that you are not afraid of failing to pass the test.

However, it should be noted that in order to avoid damage to the operating system image file, it is strongly recommended to refer to the previous article to enable “Discard OS Disk Modifications” before using the real-time save and rewind functions. On the other hand, the stability of the current rewind function is not very ideal, and there will also be crashes. It is not recommended to use it for the time being, and it will need to be updated in the future to solve the problem.

In the graphic description below, the author will directly open the settings of the two functions and demonstrate how to use them.
