how is md5 calculated about main_mister

[sorgelig]

Source code is available. md5 lib is called from mra_loader.cpp, so whole logic is there.

[sorgelig]

to get it simple, open console log and there you will see a calculated value which later you can insert in your xml file.
But since you already has CRC, you may use md5="none". CRC should be enough

[jotego]

The thing is that the CRC value is treated differently. If the md5 fails, the user gets a message. But if the CRC is not matched, the user does not get a message.

I would like the users to get the message.

[sorgelig]

then get it from debug console

The problem with that is that I handle about 1,000 MRA files so I need an automated workflow. I need to generate the md5 number the way MiSTer does automatically.

The main "gotcha" I see is that a file will be re-read and the md5 updated based on the entire contents of the file for each instance of a map. Does the md5 match in the most basic cases?

The md5 does not match for the case of a single file with no interleave. I should look at the file pointed by sorgelig to find out where it is messed up, because I think it is, at least conceptually.

I will close this one as it is similar to #741, which is mine too. I'll try to look for help to get a better implementation on the MiSTer firmware, addressing #422 too
