Howto program eproms for Z80

[Basique]

Hello!

I want to program an eprom for the gameboy.
The programmer wants to know in which format the rom-file is.
Possible choices are:
binary (formatted)
binary (unformatted)
several intel formats
...

I only know that the gameboy uses a kind of Z80 processor.
The rom is just a 32kB file with the ending gb.

Most likely this will be INTEL HEX option.

I read the specifications of the Intel Hex format at **broken link removed**

So my file should look something like that:
:10010000214601360121470136007EFE09D2190140
:100110002146017EB7C20001FF5F16002148011988

So it's an ascii-format.

But my file is complete binary. A normal text editor shows just confusing chars.
The 'file' command of linux says:

Gameboy ROM: "TEMP", [ROM ONLY], ROM: 256Kbit

So it's probably just a question of 'binary (formatted)' and 'binary (unformatted)'.

What do you think?

So most likely it is a binary file.
Attached you will find zipped EDBIN.EXE filr. This will allow you to edit any binary file; you can also modify a binary file ..

Thank you. I'll give it a try when I boot windows the next time.

I programmed the EPROM with the option "absolute binary". Because the rom-file has a size of exact 32kB it seemed quite logical.

I'll test it this week.

HEX files can have different sizes ..
Binary file can have only certain sizes, for example, 1kB, 2kB, ..., 32kB, ..
If you initially named the size of the file, the answer would have been much easier to guess ..

Oh, I thought I did

First post:

The rom is just a 32kB file with the ending gb.

Second post:

Gameboy ROM: "TEMP", [ROM ONLY], ROM: 256Kbit

Nevertheless, thank you very much for your help. You approved my guess.

Best regards,
