Death Metal:
Nice, IQ. I was really looking for a source on all needed AES patches. Thanks.

DethXec:
An Update and questions...

First, you must use Neo68KROM instead of Neo68KROM01, for all cases.

Second, kof2000 and matrim patches don't work :p - and I didn't test mslug5.

iq_132:
Matrim works fine for me...
As for kof2000, they changed the way the init for SMA-protected games works.

Find this:
static void kof2000SMADecrypt()

Add this before the last }

kof2000AESPatch();

DethXec:
Here's the matrim driver, I tried pNeoInitCallback = matrimAESPatch; in all posible places but no luck...
This is using Neo Geo Normal BIOS, on all regions. AES Mode works with Universe BIOS.

As for the kof2000 driver, I did this and I did not use kof2000AESPatch(); code in any way:
*note*: This is not the full, driver, just a little part.


--- Code: ---static void kof2000SMADecrypt()
{
for (int i = 0; i < 0x800000 / 2; i++) {
((unsigned short*)(Neo68KROM + 0x100000))[i] = BITSWAP16(((unsigned short*)(Neo68KROM + 0x100000))[i], 12, 8, 11, 3, 15, 14, 7, 0, 10, 13, 6, 5, 9, 2, 1, 4);
}

for (int i = 0; i < 0x0C0000 / 2; i++) {
((unsigned short*)Neo68KROM)[i] = ((unsigned short*)Neo68KROM)[0x73A000 / 2 + BITSWAP24(i, 23, 22, 21, 20, 19, 18, 8, 4, 15, 13, 3, 14, 16, 2, 6, 17, 7, 12, 10, 0, 5, 11, 1, 9)];
}

for (int i = 0; i < 0x63A000 / 2; i += 0x0800 / 2) {
unsigned short nBuffer[0x0800 / 2];
memcpy(nBuffer, &((unsigned short*)(Neo68KROM + 0x100000))[i], 0x0800);
for (int j = 0; j < 0x0800 / 2; j++) {
((unsigned short*)(Neo68KROM + 0x100000))[i + j] = nBuffer[BITSWAP24(j, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 4, 1, 3, 8, 6, 2, 7, 0, 9, 5)];
}
}
{
*((unsigned short*)(Neo68KROM + 0xA226E)) = 0x4E75;
}
}
--- End code ---

PD: Sorry for being so n00b, but I hate programming. I just like emulators  :D
