About This File
This patch will downgrade any legal and unmodified copy of DOOM II V1.7a to DOOM II V1.7. There are various DOOM2 upgrade patches from iD Software and a downgrade patch by FunDuke from V1.9 to V1.666; however, there is as yet no way to get plain V1.7 using these; this patch fixes that problem.
