a general workbench list and an application list for testing. Images in
those lists are either verified good or best available currently. Many
images are still missing.
homebrew. Also allowed bankswitch writes to get to the TIA for this and
mapper 3F. Finally, included a couple of demos in the softlist so to be
able to test the code in future. nw.
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]
