Projects / Re: Tool Request:decrypt all roms in a neogeo game
« Last post by dink on September 13, 2019, 06:54:52 PM »
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.

best regards,

Projects / Tool Request:decrypt all roms in a neogeo game
« Last post by brunosilva 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

I've devised a patch for HBMAME to fix the timer issue. Each affected game needs a 1-byte patch. I've fixed all the games I know about, but there's probably many others to be found.

Basically, after each second, it subtracts one in BCD mode, then checks the minus flag. This is the wrong thing to do if you have > 80 seconds. So, I changed it to the carry flag which only pops up when 00 rolls around to 99.

However, your m68000 core might work differently. I guess you'll find out. Make sure you test to check the fight ends when the time is up.

Congratulations Robert, nice find  :cool:

I try found fix and I always fail  :redface:
