Adding games

**James** · November 18, 2005

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.

**James** · November 21, 2005

<{POST_SNAPBACK}>

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

**iq_132** · November 21, 2005

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

**Robert** · November 21, 2005

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

**James** · November 21, 2005

<{POST_SNAPBACK}>

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

**Robert** · November 21, 2005

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.

**Robert** · November 22, 2005

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:
