But the company is not maintain this AP now! When I run this AP on DOSBox, the Screen(or Window) become unreadable, and …

:sad:I had set both of ems & xms to 'false', but it do es not work.

🙁 My old DOS AP say I should add the following line to the config file: DEVICE=emm386.exe noems x=a000-c9ff i=e000-efff On MS-DOS V6.22, it's OK! How to setup this environment on DOSBox ? Regards, Slong.
