From 2996000575daa582f996bba0c68c2d58d201df70 Mon Sep 17 00:00:00 2001 From: Peter Ferrie Date: Tue, 29 Nov 2016 17:34:52 -0800 Subject: [PATCH] improve the make instructions --- make.txt | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/make.txt b/make.txt index 614761d..65c99f3 100644 --- a/make.txt +++ b/make.txt @@ -1,11 +1,11 @@ How to make your own version: -Take a regular version of Diversi-DOS, and save the $BF00-BFFF and $D700-FFFF regions to disk. -Make whatever changes you will to that image. -Fill the following regions with zeroes in the $D700 region: - - the read buffer at $1DBC-1FFF; +Boot Diversi-DOS in 64kb mode, break at $DD84, and then save the $BF00-BFFF and $D700-FFFF regions to disk. +Make whatever changes you will to those files. +Then within the $D700 file, fill with zeroes the ranges at these file offsets: + - the read buffer at $1CBC-1EFF; - the translate tables at offsets $2329-2368 and $2396-23FF (the unpacker will regenerate them); - - the write buffer at $2500-2655 + - the write buffer at $2400-2555 Concatenate the two images, with the $BF00 region first (to create a file named "d600-ffff"). Reverse the order of the bytes in the image (to create a file named "d600-ffff.rev"). Compress the result with aPLib ("appack c d600-ffff.rev d600-ffff.rev.pak").
