Okay, I just made this work on the MVS multi. I was assuming the P ROM from the release was scrambled, which is not the case. You only need it scrambled to make it work with MAME. Because of the C-ROMs not being CMC encrypted it might not even be a good idea run it on MAME with the Samsho5sp slot.

Now the question, am I missing a patch for the C-ROMs, no???

The logo is different than what it is supposed to.

Just making sure I am being clear, putting byteswapped samsho5_fe.cslot1_maincpu as "prom" straight without any changes, making crom0 from ss_unswizzle.exe and odd/even 16bit combined gave me this result. The fpga, srom, vroma0 and m1rom files are from the original Samsho 5 special.

MAYBE, I am having the wrong title screen logo because I don't have the correct srom file? Can anyone check that for me?

At the original loke test, that was the screen. the additional graphics might have just been added for this release

Your bios region should be what is determining the logo screen.

Yep, that is why I put screenshots with both japanese and english logos. Well we need to figure out how to patch the CROM and SROM then...

JacKc · Jun 13, 2020

As far as i know title screen will change depending which Neo-Geo Bios you are using. So normally you don't have to patch the Cx ROMs and S1 ROM but only choose Neo-Geo MVS Bios (Asia/Europe, USA or Japan) or Neo-Geo AES Bios (Japan or Asia) in Dipswitches.

Samurai Shodown 5 Special title screen using Neo-Geo MVS Asia/Europe ver. 6 (1 slot) bios

Samurai Shodown 5 Special title screen using Neo-geo AES Japan bios

I don't patch anything but just using different Neo-Geo bios.

Concerning samsho5pfe, it seems original ROM is only Japanese region. They have made in hurry a translation into English. So first possibility, they have modified original Cx ROMs and S1 ROM to display English tilte and subtiltes. Second possiblity, a patch is apply to original Cx and S1 when loading ROMs.

For all Neo-Geo games, normally The tiles datas for all region are sets in Cx ROMs and S1 ROM (when Cx ROMs are decrypted) or only Cx ROMs when Cx are encrypted.

Of course some Neo-Geo Games are only MVS Release (so wee need to use an emulation trick to make them running in AES mode). But all AES datas seems to be present in the ROM.

nitd MVS Mode:

nitd AES mode using emulation:

The most significant case was for Rage Of the Dragons (rotd). Before AES release was dumped, and when only MVS release was available and dumped; we need to to use a pacth code in the driver to make it running into AES mode (as rotd set was supposed to be an only MVS release).

fandangos · Jun 13, 2020

and it's playable on MISTER

))

For mister you will need Darksoft's pack with the XML.

I've replaced the prom file of samsho5s with samsh5sp.cslot1_maincpu.swap
You have to do:

$ dd if=samsh5sp.cslot1_maincpu.dec of=samsh5sp.cslot1_maincpu.swap conv=swab

And I've replaced crom0 with the following:
Used the unswizzle script got ODD and EVEN files.
Used Winhex: File tools -> unify -> word wise (16bit) -> select EVEN as first file, ODD as second file.

Thanks to l_oliveira for figuring the crom0 and ack for the unswizzle script.

Made some changes to romset.xml (needed for MISTER) so you can have both.
Called the folder samsho5fe the same as the inner files of the collection.

by the way... good luck with that Neobuilder software, I tried that to create a .neo file for the MISTER before giving up and going with the Darksoft supported format, as I should have done since the beginning.

You will have the ask the devs to add the CRC to it so you can finally build a .neo file.
In the meanwhile people with MISTER and the Darksoft multi can already enjoy it

Original rom has AES and MVS mode.
English and Japanese are both present.

Just played now in AES English mode and the text was there during fight scenes.
Including options and training menu.

None because for it to work on FBA or MAME we need to encrypt the C roms back which is not possible at the moment.

Or, we can try to talk to mame devs to remove the decryption for this rom, still it will take a while for emulators.

MISTER and the Multi require decrypted roms that's why it works.

EDIT: By the way, it seems the game never was called Samurai Shodown 5 Perfect but still named 5 Special.
It seems the new name was given during the making of this collection.

That title screen you see is the correct one, the one in the collection is just a makeover.

JacKc · Jun 13, 2020

Not agree with you. We could easily make a driver to run samsho5pfe even if it is using decrypted Cx ROMs, M1 decrypted ROM, Vx decrypted ROM and S1 ROM. (of course if we have the rom for testing purpose).

See Samurai Shodown V ◦ サムライスピリッツ零 (hack of XBOX version) [samsho5x]

This set is using decrypted ROMs :

Also we have great devs who are probaly able to make some code to encrypt the CX ROMs like they have to be (if not already done...)

I think this is the best thing to do. Its a waste of time to try and encrypt these decrypted roms just so you can use the existing samsh5sp driver.
