Update neogeo.xml to take advantage of them.
For regular rom loading we try to autodetect the appropriate endianness and
width by matching the region tag to a device with a device_memory_interface;
this is generally not doable for software lists because the regions are
children of some slot device and thus not siblings of the devices in the root
driver (i.e. "cartslot1:maincpu" rather than "maincpu") So you have to
specify the width and endianness manually for now.
Anyone who has spare time, feel welcome to byteswap every single entry
in megadriv.xml and update them to use this :-)
Message that was posted to me
"Hi David
It was to my great disappointment that your work on the NeoGeo Multislot (Dec 2013) was not included in MAME. To aid the process I've taken your work and spent some hours addressing the concerns put forward by the developers. The code I'm sending to you converts Neo Geo to fully use slot devices for the cartridges and implements the multi-slot using techniques that have greater likelihood of being met with approval.
In some places the slot trampolines caused performance to drop below 100% so I've used methods to avoid them gathered by the study of other slot devices in MESS. Performance is the same as it was prior to this update.
I first sent this with the forms on the official site but received no reply so I'm turning to you directly.

this is mostly functional but about 2 years old now, and badly needs some modernizations. It's a bit ugly in places because I've had to make sure the legacy methods work too, although in other places simply because it's old code I never quite got around to cleaning up.
basically the inits have been split into ones that need calling once on startup (decryptions etc.) and ones that need calling when a new slot is activated (custom banking / protection handlers)
mame64 neogeo -cart1 kof98 -cart2 kof99 -cart3 kof2000 -cart4 kof2001 -cart5 kof2002 -cart6 kof2003
works, assuming you have the RAM. certain combinations / orders don't work, maybe the real system is like that, maybe there are flaws in the implementation.
once loaded as multi-game the neogeo will run through the attracts of each game in order, if you insert a coin then you can select next / previous game with the '3' and '4' (which are mapped to those buttons on the system) just like real hardware.
if you're low on memory try
mame64 neogeo -cart1 lbowling -cart2 samsho -cart3 mutnat -cart4 pbobblen -cart5 neomrdo -cart6 turfmast
instead
if you want an example of where it fails right now then put -cart1 roboarmy in slot 1 instead, it hangs after cycling through the games (or moving through them with 3) it's possible something isn't reset properly. This might become clearer as I clean things up a bit.
I've verified eas and neocdz work as before
* Cleaned up large amounts of duplicated code between the MAME and MESS (AES/NeoCD) drivers
* Removed MVS-only ROMs and devices (SM1 ROM, SFIX ROM, upd4990a RTC, etc.) from AES/NeoCD
* Replaced legacy NVRAM in MVS and NeoCD with NVRAM devices
* Correctly hooked up SM1 ROM bankswitching; the BIOS sound test works now
* Corrected VRAM size
* Sorted the Universe BIOS versions and unified them between MAME and MESS
* Fixed kf10thep ROM loading and decryption which was a horrible hack (and not endian safe)
* Replaced svcplus protection hack ROM patch with a less invasive one, based on FBA
* Started marking code and data that should be moved out into devices
* Various other code and comment cleanups
New clones added
----------------
Kizuna Encounter - Super Tag Battle 4 Way Battle Version / Fu'un Super Tag Battle Special Version [Alex Jackson]
* Marked quizkof MVS AND AES VERSION
* Cleaned up all labels (consistent for all protos now) for prototype sets (in 99.9% of the cases the correct labels are not known) to: proto_ID-XX.XX
* Identified product codes for viewpoint, savager and blazstar
* kotm2p m1/s1 parent/clone fix
* Documentation update
* Reflected changes in internal db to xml (except /* Plane x */ )
multislot support [David Haywood]
Please note: launching convention for Neo-Geo games is now the same as
MESS software lists "mame neogeo gamename" or "mame neogeo -cart
gamename".
