I find it very funny to be useing fully decrypted sets in Mame.

 

My kf2k2pls uses a decrypted S rom NEO_SFIX_128K( "265-s1p.bin", CRC(595e0006) SHA1(ff086bdaa6f40e9ad963e1100a27f44618d684ed) )

I never knew it used a encrypted one ( or did I ? )

I'm not impressed with myself after that. I already had all that code - except for the line that mattered.

if (!strcmp(Machine->gamedrv->name,"cthd2003") ||
!strcmp(Machine->gamedrv->name,"ct2k3sp"))

I only had cthd2003 there, don't know how I could have overlooked it. Thanks James, it works fine now.

 

Metal Slug 5 Plus- does anyone have the driver?

 

Lastly I've been looking at the kof96m_ep1.rom, it's either corrupt or encrypted?? Any answers?

 

EDIT: never mind, I got the kof96m_ep1.rom encryption sorted out, and it works.

 

Still need a working ms5plus driver though !!

kf2k2pls: I found I had the decrypted roms, and it ran straight away. problem solved.

 

ms5plus: That's a really old driver, and I don't have the v roms.

 

I've tried mixing/matching, but no luck yet.

 

What I've got is the set for kawaks 1.48/dev, so I'd like to get it working with that one if possible.

Why that one ? They were known to be bad rom sets and the emu is just as old as the driver posted here.

Yeah... If you're going to go off of any reference, you should definitely go off of Johnboy's dats.

I can only make use of what i've got. There's no point making a driver if it can't be tested.

 

Well maybe you can get patches to get the right roms. I am sure there will be people eager to help.

Upgraded to 0.102, and found that mamedev had changed a few things. All fixed and working.

 

ms5plus: ok, the rom problem is settled, and I've progressed to getting the red screen, but that's it. I give up on this one.

Never say die!

 

ms5plus: Found a very embarrasing mistake, once this was fixed the game started, with corrupt graphics. Since the graphics roms were the same as mslug5, I added the kof2000_neogeo line. Now the graphics were fixed, but the flashing PLUS was gone. Hmmm.

 

Decided to investigate neocrypt.c and made a modification which fixed the problem. This mod allows a s1 rom to overrule the inbuilt text on any game of this type in the future.

The final code for ms5plus:
