DiagROM for ST

[PaulJ]

Not using a cart, using it as the boot rom. Took out the tos rom and put in DiagROM, applied power gray screen, no serial.. same all computers.

Maybe your programmer is byte swapping the ROMs ?

STE? or ST?

Anyways I have tested the 256K version in a real machine. I havent tested the 192K version in a real machine. So you might need to resplit the roms.

Checked the burn in the 16 bit eprom and all the text is readable so its not byte reversed.. This has to be something stupid!!

Post the file here and I will byteswap it for you if needs be.

Heres the beginning and end of the file. I am burning it into a 27C4096 16 bit eprom. Looks fine to me. Compared it to a TOS 1.04 image and in both the text is readable. I didn't see any way to upload a binary..

not sure how your setup is working but I had to byteswap the rom image to get it to work on the Amiga. My ST setup has hi and lo roms.

I'm burning the file as is into a 16 bit eprom. I do the same for TOS which I have compared to. Both files have the text readable which means both files are not byte swapped. I have done a byte swap and attempted execution with the same results. Out of curiousity what did you use to assemble the code? This is really strange..has to be something stupid...

[terriblefire]

It was assembled with vasm. The code is assembly anyway.

Try using the rom with Hatari before going any further
