Putting TOS & EmuTOS on 1 ROM (I forgot!)

[Steve]

Hi, so sorry for this question but I've completely forgotten how to put regular TOS and EmuTOS on 1 ROM (a 4096) For some reason I can't find my old notes!

If someone could quickly remind me or point me to a post/thread where it's explained I'd be very appreciative. Do we merge 2 roms on the linux command line? I can't remember! :)

romwak.exe does a good job under windows, and in above thread there are a few useful batch files shared

You just have to pad each image so that they are both half the size of the ROM and then join them together.

In Linux/UNIX you can do:

Code: Select all

dd if=image1.bin of=image1-pad.bin bs=256K conv=sync count=1
dd if=image2.bin of=image2-pad.bin bs=256K conv=sync count=1
cat image1-pad.bin image2-pad.bin > dualromimage.bin

Thank you both :)
