in the softlist. The official syntax to launch disk games is now
mess famicom -cart disksys -flop gamename
which corresponds to inserting the RAM expansion cart with
connected the disk drive into the cartslot and the desired disk
in the disk drive (exactly like you would have done with the
real thing). In this way, you cannot mount anymore both a cart and
a disk in the Family Computer (as in a real unit).
Users that cannot cope with this limitation and/or with the new
syntax can still use the famitwin driver (which offers both cart and
disk options) or the newly added driver fds which emulates a
famicom with the expansion always inserted: in both latter cases
the old syntax
mess famitwin -flop gamename
will launch the game, as previously. [Fabio Priuli]
(MESS) famicom: fixed disk system IRQ latch clear in Kaettekita
Mario Bros. based on investigations by FHorse. [Fabio Priuli]
Out of whatsnew: For the moment I gave up the original plan to
also modernize the floppy drive and the disk format. If anyone
wants to look into these, be my guest :-)
- Fixed YM2151 clock in XM expansion, thanks to info from
tep392 and GroovyBee
- Added support for homebrew boards MegaCart+ and
VersaBoard by CPUWIZ (ROM respectively up to 512K
and 256K + 32K of RAM)
- Misc cleanups
out of whatsnew: I have also added, for debugging purposes, a VersaBoard with SG 9banks + POKEY at 0x0450
in the hope to find out exactly what goes currently wrong in the emulation of some homebrew games... let's see...
and partially implemented the required mapper [Team Europe, Fabio Priuli]
after selecting a game, the CPU always points to the correct bank of the cart,
but some games don't work anyway (e.g. Duck Tales, PacMan, etc.)
I don't have time to further debug this, at the moment, so I leave it to whoever
wants to take a look
- Rewritten cart emulation to use slot devices (many
"mappers" do not fully work) and unified cart handling
among 8bit home computers, XEGS and Atari 5200
- Added support for loading carts with bankswitch to all XL/XE
models
- Added support for loading XEGS carts in Atari 8bits home
computers (XEGS instead will only load XEGS games until
support for the keyboard add-on is included)
- Big clean up of the driver, simplifying memory map, removing
writes to ROM, etc.
- Changed NOT_WORKING flag to IMPERFECT_GRAPHICS
in 600XL, 65XE, 800XE and XEGS since they should now be
working to the same extent of the 800XL, and bugs shall be
reported.
as a consequence of the above changes, the new softlists a800.xml, a5200.xml
and xegs.xml are not compatible anymore with 0.154: keep the old xmls until
0.155 if you don't compile your own exe
expansion board, thanks to info from tep392. nw.
Also removed from the softlist the Donkey Kong XM Enhanced
version which had been hacked to work on ProSystem emulator
and fails to save hiscores with correct HSC emulation
(it remains available the correct version which saves fine both
in MESS and in the real hardware).
- Rewritten cart emulation to use slot devices
- Removed POKEY chip from the main unit since it was inside
the carts (of course it gets enabled when you launch a game
who contained it in its cart)
- Added support for the High Score cart as a passthru cart: when
you mount hiscore, a -cart2 switch will become available to mount
the game you want to play
- Properly implemented XBoarD and XM expansions as
passthru carts as well, so that new syntax to run dkxm.a78 is
"mess a7800 -cart xm -cart2 path\to\games\dkxm.a78"
High Score support for XM shall work as well.
- Big clean up of the driver, simplifying memory map, removing
writes to ROM, etc.
Out of whatsnew: In conclusion, a7800.c has been brought into the new millennium ;-)
the implementation and removed Supercharger tapes from the main system.
The -cass media switch (to load the tape file) will become available only
when you mount the Supercharger cart. [Fabio Priuli]
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.

(and Suikoden - Tenmei no Chikai) can be considered as working. Also fixed wrong
battery size for Aoki Ookami to Shiroki Mejika - Genchou Hishi in xml, which was causing
a "Memory Over" error message ingame. [Fabio Priuli]
out of whatsnew: apparently the current WRAM mirroring (based on nesdev wiki notes)
causes glitches in some of these games. I hope to improve this soonish.
battery is found. This allows for loading factory formatted sram/nvram from softlist. [Fabio Priuli]
(MESS) nes.c: Fixed Silva Saga, which relies on SRAM not being 0x00 filled from factory,
with many thanks to naruko for investigating the problem. [Fabio Priuli]
runs properly now), added second external slot -cart2 (same functionality
as -cart1). Expansion ROM slots, which are handled as internal cart slot,
are now accessible via -cart3/-cart6 media switch, until they are converted
to proper slot devices. [Fabio Priuli]
emulation of JY Company PCBs (mappers 90, 209 & 211). It's still
too glicthy to be promoted to working state, but you can now see
how Super Mario Wolrd, Contra Spirits, Donkey Kong Country 4
and Tiny Toons Adventures 6 were like. nw.
pass-through cart. Correct syntax to launch e.g. Dizzy The Adventurer
is now "mess nes -cart ade -cart2 dizzyadv". Moved Aladdin minicart
dumps to a separate softlist (but you can load in -cart2 iNES files from
fullpath, if you like) [Fabio Priuli]
nes_camerica: simplified emulation of the BF9096 board and fixed
emulation of GoldenFive board (used by the Polish Pegasus 5 in 1
cart). [Fabio Priuli]
out of whatsnew: this commit completes the recent work about emulating properly the
different pass-through NES/Famicom devices and their corresponding mini-carts...
there should be no more games requiring non-standard syntax to be launched.
slot. The two Senyou Cassettes (Top Hit 20 Vol 1 & Vol 2) have now to be
loaded with the following commands "mess nes -cart karaoke -cart2 top20v1"
(or top20v2). This is accurate to the hardware, because these expansions
had to be manually inserted into the body of the main Karaoke Studio cart
before playing. [Fabio Priuli]
now select songs and see the animation, even if I would not call playable the
games this way. [Fabio Priuli]
out of whatsnew: the expansion slot is currently hacked around at loading time.
I will soon implement it as a subslot, but I still need to check a few details first.
added a skeleton list I used for some quick testing.
the driver really needs a significant overhaul, but at least this makes usage a little less opaque.
Datach games have now to be loaded with the following commands
"mess nes -cart datach -cart2 gamename" where gamename can be
either a shortname from the datach softlist, or a fullpath to the iNES files
(or to headerless 256k dump of the Datach minicarts). This is accurate
to the hardware, because Datach carts could not be mounted in the main
Famicom cartridge slot. [Fabio Priuli]
out of whatsnew:
+ fixed a small bug in handling MMC-1 games with > 8K of WRAM (only a Jpn baseball games use this,
and I can see no difference in behavior)
+ updated emulation status in xml for a few games I had made working during slot-ification
* hacked around the limitations of our PPU code, so to support the different CHR registers
* implemented Extended Attribute Mode (Ex1)
* improved PRG-RAM handling
* simplified NT-RAM handling
* first attempt to add split screen mode, still broken
out of whatsnew: this was for sake of messnew inclusion ;)
- moves ec184*, iskr103* and mc1502 out of pc.c
- moves CGA font upload support to a subclass
- adds new drivers: poisk1, ec1847, pk88
- adds a skeleton of native iskr103* keyboard
i8089: implement remaining instructions and support execution from "io" space. [Carl]
(mess) isbc-215g: add intel isbc-215g hdd controller, read only for now [Carl]
(mess) isbc: add hdd support to isbc2861 (nw)
