auto-checksum utility

(1 / 1)


ANNOUNCING! The end to last-minute, late-night checksumming of roms...

No longer do you need to make two or three passes to get valid checksums

for your files.  CKSUM.EXE will accept any EXTEKHEX or VLDA file format

and append records to it that will patch in the correct checksums (using

the algorithms from GAUNTLET and SYSTEM I).  Then you can download this

file into a devsys or IMI and violin! it works!

  To use it, create a file .CKS with one line for each rom bank:

:::::::::::: example ::::::::::
CKSUM0	10000	27128
CKSUM1	18000	27128
CKSUM2	20000	27256
:::::::::::::::::::::::::::::::

then respond:	CKSUM >filename		( for .HEX files )
  or		CKSUM >filename.VLDA	( for .VLDA files)
  or		CKSUM >HELP!		( for help on options )

the file to run is:	KIM$USERDISK:[LIPSON.CKSUM]CKSUM

  This assumes that your system uses a seperate low address/high address rom
for each rom bank, so 6502 systems are out of luck. Please let me know if you
have any other memory organization you need supported.
