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 :-)
(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]
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.
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 ;)
