Hello,
or create folder games with sub-folder dos;) I really was digging around LFN long tims, because full name is much user friendly then dos_ga~1. The patch exists, but it is not so easy. After reading various comments on Vogons I made decision to not include it to mDosbox. In addition this patch breaks some dosbox functionalities and was excluded from dosbox-x with message :
“sorry. LFN patch completely breaks file I/O in DOSBox. reverting.”
