MD5 codes of good roms (idea for n64 emulators)

[Hacktarux]

I am currently writing the ini file format of mupen64 and searching what info should i put into it. I think that it should be usefull if the emulator can detect good and bad dumps. And maybe, other emulator authors can be interested by implementing it in their emu (actually it is more usefull in other emu than mine ).

Here, you'll find the md5 codes of almost all the good roms (thanks smiff for the help )

And source code of the little utility that have generated this file.

Sounds nice, just one question:
All those codes were for the z64 format, what if the rom is in another one? Wouldn't that change the MD5 code completely?

[Hacktarux]

My utility swap roms to z64 format before calculating the MD5 code.

[Slougi]

What i meant is that if the end user has say, a rom in V64 format, will it still recognize it?

[Hacktarux]

If an emu authors want to implement it, he will have to do the same : byteswap to z64 format and calculate the md5. (Or modify the md5 source code so that it swap each word before using it) It is not hard to do but it depends on how the loading process is actually done. This process is done internally, there's no need to change the actual format of the file in the hard drive.

For example the smiff's conker's bad fur day rom in z64 format has the same code as mine in v64 format. (it is one of the roms i have verified).

I don't think it will be long to calculate it, but i think the end user have to be able to disable it.

Ah sorry, I didn't get your point correctly! /slaps self
So basically the rom would always get byteswapped to z64 and after that compared to the MD5 code? How would that work for rom browsers?

[Hacktarux]

I depends on how it is implemented on the emu :
- it can be check when the rom is actually loaded (the emu warn the user and ask if he wants to continue)
- it can be done when the user change the directory
- it can be done by an option included in the menu that check a file or a directory.

Or ... any other suggestion ?

hacktarux..


i've got the current n64 rom set (-2 unreleased)

if you want to give me a binary (since i have no idea how to compile.. i'm a non-coder ) i'd be happy to generate a list for you.

[Hacktarux]

The binary is included in the source code (you need the .exe and the z.dll file). The utility browse automatically all the subdirectory and zip files.
