MS-DOS Player for Win32-x64 (2012/12/23) Changelog (Google Translate):

to support (RAW disk write) int 21h. in writing to the disk so that marucopy works. However, we are allowed to write the floppy disk only for your safety. In this context, I have modified to get the correct media type in the DPB. Such as a USB memory is treated as a hard disk. I also support the int 21h, ah = 1bh/1ch (get information FAT). Fixed a crash in 21h, ah = 0eh int, the wrong drive is specified. Crash at startup has been resolved in LIST.COM. (You're like the premise of screen mode PC / AT, LIST.COM itself at present, but will not work) Others, (get code page, change) int 21h, ah = 66h or support, or to support int 21h, ah = 67h (specifying the maximum number of files), PC BIOS support or some such services or do not know whether or not to use, Has been variously modified, I forgot that the fine (laughs)
