Split/join ROMs (kickstart ROMs)
Is it possible to "make" using software, the single kickstart ROM from an odd+even version OR the opposite (split a single kickstart to odd+even)?
EDIT: Actually found how to merge, it is as expected easier. But I am looking at splitting actually. Last edited by NLS; 07 September 2018 at 11:16. |

Remus is the reverse of Rom Split. I think they are on Aminet.

I've uploaded EpromSplitMerge.zip to the Zone. Get the usage from the command syntax. I hope it works for you, since I didn't use it anymore the last 25 years.
RomSplit and Remus are for extracting Rom modules and building new custom Roms from a bunch of modules. Last edited by PeterK; 07 September 2018 at 17:21. |

I've used a little ARexx script for joining:
Code:
/* REXX */ parse arg oddfile evenfile joinedfile . if joinedfile='' then joinedfile=’joined.rom' if ~open(odd,oddfile,READ) then exit 10 if ~open(even,evenfile,READ) then exit 10 if ~open(joined,joinedfile,WRITE) then exit 10 do while ~eof(odd) low=readch(odd,2) high=readch(even,2) call writech joined,low || high end say seek(odd,0) 'bytes read' say seek(joined,0) 'bytes written' |

The software my EPROM programmer came with has a menu option to split a 16 bit buffer to files.

I actually want to split a single 128k ROM to 4x32k (odd/even)... The problem is of course how to split in half and those halves to odd/even.
I don't think I can do it. |

You could split the 128 kB into 2 x 64 kB with FileX and then use my EpromSplit for the 64 kB files to split them into odd and even.

I actually wanted to use Windows software (sorry, easier at my current location), but did succeed!
The actual 128k ROM, needed FIRST to be split in odd/even and THEN split the odd and even in two! (in other words NOT first split and then make odd/even) Thank you for your help. |
