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.
