As I’ve done in a few other Speeders (Albion, PSO, BDO, NW), I’ve added a console window to the .dll version of Lost Ark Speeder. This is a safer method of inputting/outputting text that does not rely on text files. It also emulates the .exe version exactly, so there is basically no difference between them. Note that not all (but most) programs support a console window, so you may have to try multiple programs. As always, Task Manager, Notepad, and most Microsoft software work fine.
This change requires updating Speeder to version 90. You can find the latest version by clicking the "MEGA Folder" button in Launcher.
