AFAIK:I'm a gamer not a tech head.
Metal Slug X works!
Why it's so important that it passes a CRC check, can anyone tell me:-
What do the numbers mean?
Whats the difference in a pass and non pass game wise?
Who's in charge of the unibios CRC check?
Whats does it check?
The big one is can it be faked to pass CRC?
Now the Multicart is out is there a need for a Unibios ? ( apart from checking CRC )
CRC is a checksum of all the gamedata as it is seen by the PCB. If it passes it means it is bit by bit the same as the original cart.
Unibios was made by Razoola
And if all you want is a working game your bar is pretty low. I mean you could just get a RaspPI, install Retropie and have a perfect Neo Geo emulation with all the games working.
