MVS conversion Kabuki Klash on Progtop/cha256

You have to look for the bootleg version; the original is encrypted.

@pierpa86 , I have one question, does Nightmare in the Dark have encrypted ROMs? I downloaded it from Planetemu, but there's no file for S1 in the archive.
Yes it is.
All game on CHAFIO is encrypted, so take the decripted version. You need C/S rom decripted.

Nightmare in the Dark (decrypted C)

You can also run decrypt it from mame.
 
Wait what ? 8|
Where the this problem come from ?
Do you know some detail ?
I probably never noticed and that's very interesting. Is it the dump's fault?
Is the problem also present in the original version?
Short version is the official release has a bug. It reads the audio at a slightly offset memory address, so some sounds start late and have a pop at the end. The thread I linked shows the address in question and the single change needed to fix this. There are links to download the fixed roms in various formats there as well.

Code:
260-v1.v1:
0x50820: 6E -> 08

because of this I play with the fixed roms on a flash cart (I seem to have collected all three currently out there) even though I have an original cart in the Horde.

really interesting thanks :D
one thing I remember was that this game becomes very slow, who knows if an optimization like metal slug 2 is possible
 
Looking at the 8 MB of c sprite decrypted you can see that the last 4 MB are practically empty.
looking at the sprites written at the end you can see this:

they don't seem like coherent sprites, they could be the result of the decryption process and not used sprites, the game also works with the first 4MB of C1 and C2.
