Subject: 2 small patches
Here are two small patches.
The first one remove a profiler_mark that has been forgotten in one of
the
last update in the tx1.c video driver.
The second is a small speed up in the neo-geo driver which gives a 0.5%
speed up on my machine.
- replace a loop with an equivalent memset
- remove a useless parameter I forgot to remove in a previous patch
Hope this help.
Best regards,
CJ
- Reworked the button-lamps matrix system.
- Documented both output ports.
- Connected coin in, key in and payout counters.
- Improved the lamps layout to be more realistic.
- Updated technical notes.

Delete previous submission! Functionally the same, just reordered
some source and added a comment. Thanks!
Space Duel: Add the P10/11 dip switch (only 4 switches instead of the
standard 8)
Let me know if you have any questions.

Note that this is caused by leaving entries in the bitmap
with an index larger than the palette size. This is forbidden
and now can lead to a crash in debug builds.
Added preliminary LD-V1000 emulation. Not fully working yet, but mostly
there.
Cleaned up and normalized the three existing laserdisc emulations.
Removed obsolete code from the laserdisc core.

still not really convinced by this conditional dip stuff.. it stands no chance of working on games where the coinage mode is in eeprom... (but i have no better suggestions)
02483: gunlock, rayforcj: Title screen trouble
02482: bubblemj: Demonstration screen trouble
* Check for whether tile is opaque must honour extra planes.
- added rom decryption
- patched protection checks
- mapped extra inputs
Game is not playable due to heavy gfx glitches caused by bugs in SNES hw emulation.
[Andreas Naive, Tomasz Slanina]
* added missing button mappings
* corrected dip switch
This seems to be a prototype. The number of remaining ships displayed is not correct.

Cleanup is not completed.
configuration builder to use these functions. Also changed the laserdisc
player devices to use them. Updated Z80 CTC/SIO code to assume that the
CPU provided for the clock is relative to the device that the CTC/SIO
belong to. Updated memory code to assume that regions and devices
referenced by the memory map are relative to the device the associated
CPU belongs to.
Readded UI_ON_SCREEN_DISPLAY to be changed again in the "Inputs" menu as per Aaron's request.
A clean build is required and cfg/default.cfg has to be deleted !

Subject: Small SNES changes
Hi,
enclosed please find a patch which changes a bit the way SNES
carts (NSS & bootlegs) are loaded at init time. Currently, data
are loaded once at start and then the read handlers perform various
mirroring tricks. With the attached patch, the cart is loaded at
init and mirrored as many times as it is necessary, while handlers
simply read from the plain offset. Also, blocks of data are mirrored
until they fill all the available banks. Implementing this behavior
both simplifies the handlers code and is more faithful to the hardware
(see mirroring note included in the DRIVER_INIT).
I also slightly changed some handlers to take into account the new
mirroring system. OTOH sram_handlers haven't been updated (they will
be eventually) because with carts as small as the ones in nss.c and
snesb.c, they basically have no overlapping with the new mirroring
approach... as soon as I come up with a satisfactory implementation
that works in MESS (which has to deal with much larger carts), I will
also submit the MAME side.
No regressions appear with the patch, as far as I could test.
Regards
Fabio

Subject: further snes changes
Hi,
enclosed please find a patch which rewrites memory handlers in
machine/snes.c to take into account the additional cart/memory layouts
(mode 22 & 25) which were available for the home console (almost no
impact on nss.c & snesb.c, which only use mode 20 & 21). rather than
only add a bunch of if(snes_cart.mode == XXXX), I preferred to slightly
rewrite the handlers. main changes on the MAME side are:
* merged regions 0x700000 up to 0x7dffff in snes_map (this allows to
make memory maps in nss.c and snesb.c identical: the zone previously
NOPed in nss.c is now handled by snes_r_bank5, because it was not
reserved for all cart types)
* split region 0x800000-0xbfffff from 0xc00000-0xffffff in snes_map.
This simplifies a bit handlers used by MAME and it will be necessary
when MESS supports special chips like SDD-1 (which dynamically changes
the part of cart loaded in the latter region)
* slightly enlarged SRAM regions (in this case, it only affects what
happens inside the handler, NOT snes_map) to support carts with 512kbits
of SRAM (e.g. Thoroughbred Breeder III for MESS). I'm still not 100%
satisfied with SRAM mirroring, but this is closer to the real thing
than the previous way to handle it
No regressions are present, neither in MAME nor in MESS, as far as I
could test (well, for MAME weren't expected, since most changes affected
mode 22 & 25).
Regards,
Fabio
