JJSCDROM.dmd is a modified version of OS/2 CD-ROM / CD-RW / DVDs device manager driver (OS2CDROM.DMD), based on the latest OS/2 DDK on-line source code.

Takayuki 'January June' Suwa has updated JJSCDROM.DMD so it can be used together with UDF.IFS and CD-RW Writers. Hopefully some more writers will work than with the original os2cdrom.dmd.
