When creating a1200 roms for burning. After splitting and doubling, do I need to use byteswap 2 or byteswap 4 to create the required bin files for burning to 27C400.

Guess it normally should be:

Double if you need to.
Byteswap 2 to take account for high endian.
Then split wordwise.

Hope this helps.

Hi Stefan,

cool program - thanks!!
Would it be possible to add a bytewise split/dissect? That could be helpful!

Hi Twanger,

I'm busy working on the 1942 project at the moment.

However, I also considered adding bytewise operations and will take a look at this when there is some time.

Regards, Stefan

Okay, just gave it a shot and burned some midnight oil.

Version 1.28 released.
Including bytewise merge and split.
Download at post 1 as always.

Enjoy!

Thanks!

Byte split is juicy for the CDTV extended roms.

As an idea for future releases, it would be great if you could add support to the CD32 roms with their special interleave.

This is an example of the same operation with srec_cat, starting from the standard and extended CD32 Remus files:

Code:
srec_cat.exe KS_32_CD32_std -Binary -Byte_Swap -Split 4 0 2 -Offset 0x40000 KS_32_CD32_std -Binary -Byte_Swap -Split 4 2 2 -Offset 0xC0000 KS_32_CD32_ext -Binary -Byte_Swap -Split 4 0 2 -Offset 0x00000 KS_32_CD32_ext -Binary -Byte_Swap -Split 4 2 2 -Offset 0x80000 -Output 2_KS_320_CD32_1MB_byte-swapped.bin -Binary

srec_cat.exe 2_KS_320_CD32_1MB_byte-swapped.bin -Binary -Crop 0x80000 0x100000 -Offset -0x80000 -Output 3a_KS_32_CD32_bank0.bin -binary
srec_cat.exe 2_KS_320_CD32_1MB_byte-swapped.bin -Binary -Crop 0x00000 0x80000 -Output 3a_KS_32_CD32_bank1.bin -binary

I've implemented the CD32 interleave algorithm. Hope I got it right, guess it is, but I didn't test a lot so please check and leave feedback.
Note that you have to manually byteswap after merging, but that's only one click.

Eprom Hexxer 1.29 is in the zone.

Eprom Hexxer - Eprom Binary Tool

You rock!! Thank you so much

Will test it and let you know.

EDIT:

Well done!

It looks good, because i compared the CRC-32 of the EpromHexxer CD32 3.2 rom with the one sucesfully used.

The first rom to be provided is the Remus Extended then the Remus Standard, finally ByteSwapped2.

Yesterday I finally tested the new version for splitting CDTV Roms.
Works perfectly, thanks again!
