byteswap amiga rom image

[soviet9922]

Hello i need to byteswap an amiga rom image and my eprom burner vs4800 don´t let me do it.
I read that hexview can do it but i cant find the option in the menu.
Somebody know how or what can i use to byteswap ?.

Thanks.

Do you have a Windows or Linux system you can use? If so, use srec_cat

If you need to byte swap 16-bit words try this:
srec_cat infile -byte-swap 2 -o outfile

If you need to byte swap 32-bit words try this:
srec_cat infile -byte-swap 4 -o outfile

If the input and output files are binary instead of some hex format you need to specify that:
srec_cat infile -binary -byte-swap 2 -o outfile -binary

Much more detailed info and examples on what srec_cat can do:

Thank you very much for the information, i´m not sure if the amiga 500 kickrom image is 16 bit or 32 byte words i´ts a binary for sure going to try booth and see what works.

There is an Amiga program called Remus that will let you compile your own Amiga Kickstart ROM image. It will also let you byteswap as well.

Hi,

I'm new to EPROM programming.
The checksum fails on my A3000's V40.68 kickstart roms. I found an EPROM programmer, and now I'd like to prepare the two bin files required for the two chips.
What command do I need to run to split a 512kb .rom file into two .bin files suitable for the EPROM programmer? I've heard you need to use srec_cat's -split function to generate the two files, and also 32-bit byteswap it.
I tried various commands, ending up in different filesizes.

What's the required file size anyway?

Thanks in advance for helping
