Tool Request:decrypt all roms in a neogeo game
« on: September 13, 2019, 12:18:14 PM »
Hi
there is a new project of a neogeo core in an FPGA: Mister https://github.com/MiSTer-devel/ , https://www.facebook.com/groups/1870135613286506/ , http://www.atari-forum.com/viewforum.php?f=117

this is working good but doesnt read encrypted roms. The goal here is to have both sets (mame/hbmame) working there but i didn't find any tool that decrypts all the files for each game.

already exists this tool? its "easy" to make one?

Thanks

Have them take a look at fbalpha source burn/src/drv/neogeo/neo_decrypt.cpp and of course the driver code to see how it's used to decrypt after it loads in the rom data.
