Alamak jadi ingat jamannya desktop masih berupa disket 1.44mb dan disket yg gede, bawaannya bawa program wordstar, lotus 123, dbase I, II, III+, dan game pre historic itu sudah seneng banget... Perintah debug/edit(lupa) tapi ga tau debug apaan... Baru sadar itu mode real sekarang. Buat genz coba deh baca bahasa assembly yg ditulis s'to buat pahami memori yg ga flat...

Hahahah, GenZ nya harus Mustafa kalo yg lain tidak mau pasti.

MS DOS DEBUG + Batch File searching for 8x16 character set in memory of DosBox.
Press space for next 16 bytes
Press escape key for exit
Start Batch File with segment and offset address attached. Make sure that the offset address can divided by 16.
Example:
C:\>MEMSPY.BAT C000 1A00
@echo off
REM MEMSPY.BAT
REM Display 16 bytes
REM Need two parameter attached
REM for segment and offset: like C000 1700
REM Space = next 16 bytes
REM ESC = Exit

Ga mau pake Debug :D
