- the return type is UINT8, consequently the designer needs to ensure that the node delivers adequately scaled data.
- input nodes allow the input data to be scaled. The return value is the node value *after* scaling.

Subject: Tiny speed up in 'src\mame\video\neogeo.c'
Hi,
here is a patch against 'src\mame\video\neogeo.c'
This patch give a tiny speed up in neogeo rendering and, IMO, gives the
source code more readable.
This is achieved by unrolling a loop in 'draw_fixed_layer'
Doing so, the logic inside the loop is simplified, less arithmetic is
performed and branches are avoided.
Hope this helps,
Best regards,
Christophe Jaillet

Subject: Quick fix for the F6 toggle
Hi
My last diff got altered before getting included, I appreciate this would likely get done (and many
thanks for doing it) but it did lose the F6 functionality when a cheat was selected. Eg. if you have
the cursor bar over Infinite Time then F6 will not work. My original solution using numbered calls
was not ideal but it did work, I'd spent ages trying to find the appropriate routine to call without
joy. Annoyingly I just tried again with 0.134 and it took less than 5 minutes to fix it
properly....DOH!!!
Anyway I've attached a simple one-line diff for 0.134 to hook up F6 wherever the cursor bar is on
the cheat menu screens.
It just changes this in uimenu.c.:-
- if (exclusive_input_pressed(menu, IPT_UI_TOGGLE_CHEAT, 0))
+ if (ui_input_pressed_repeat(menu->machine, IPT_UI_TOGGLE_CHEAT, 0))
Martin 'Pugsy' Pugh
- this emulates the RS/WS and READY handshaking according
to the tms5220 manual. Drivers reading the ready line
should most probably use it.
- Note: For cases where the READY handshake is done by the cpu
sufficient cycles have to be burnt to simulate that the
cpu waited. This yet has to be implemented.
- use tms rom clock as sense input for the s2650. darkwar now speaks again on startup.
- only one latch used for sound & speech.
- hooked up 393Hz signal to "dac3"
- pcb pictures indicate discrete logic on the sound board. Marked all games as GAME_IMPERFECT_SOUND since we seem to miss some sounds.
- 4bit dac remains mysterious
(Off the record)
I verified this thing against IDA Pro's 56156 disassembler and the docs.
Every time I found a bug in IDA's disassembler, I cross-referenced the
manual. There remain 3 opcodes which are questionably disassembled,
since even the manual is ambiguous on the details, but beyond that,
this thing should be 100% correct.
Whew. This might have actually fleshed out a bug in the
disassembly/execution. Time will tell...
CVS:
- hook up speech cpu
- get rid of "temporary" code which hardwire ctl & pdc writes
tms5110:
- Implement ctl port input/output for status reads.
- Input/output is switched by clocking pdc after a TALK STATUS command.
- update drivers to support new tms5110_ctl_r
Not worth mentioning, I think. NSS bios does not need update, so it's a minor change for MAME (but necessary for the possible legal issues of including those bits in the source)
This system is based on a custom CPU. Graphics are decoded but only 2 bitplanes hooked.
All the needed devices are in the driver, but commented out till can properly decrypt the program ROMs and identify the CPU.
About the encryption scheme, see the driver notes about my findings.

After a chat with Tafoid, I'm unsure about whether or not I should have demoted kazan and dirtfoxj, as these games worked fine before, and broke due to a bug somewhere. What's the policy on the 'not working' flag? Does it only apply to games that were always broken since the 1st day it was submitted? This can also be important regarding mametesters bugs: reports on non-working games are not accepted.

This fix mantis 03433: Jolly Card, Royal Card, Lucky Lady, Royal Vegas sets (and others)...: All games that need NVRAM initialized aren't working anymore.
* Discovered and documented new features in Jolly Card (Evona Electronics).
* Removed the commented hack for joly980 driver init since is not needed anymore.
* Fixed a bug introduced with the massive input change, that didn't allow initialize
all sets that need the normal procedure to do it.
* Updated technical notes.
so this code will crash if machine == NULL and the keycode was not a built in
keycode. Changing this so that it will gracefully fail if machine == NULL

This fixes the plane order in the gfx deodes for Black Touch '96 sprites, and Poke Champ sprites.
The Poke Champ backgrounds make absolutely no sense to me tho, it seems impossible to get the
colours in palette ram to align with the planes of the tile data, see the Korean flag ingame with
the obvious R/B colours in the palette which can't be achieved through any combination of order swapping.

I've added some verbose debug logging to the little robin 'vdp' writes,
which might come in handy.
I plan on looking at this further, but would rather check in these
changes as they give a clearer picture of what's happening with the VDP
which may help determine when it writes data, what modes it attempts to
set, and therefore allow more educated guesses at the expected behavior.
I can't imagine it will actually be too hard to get working, we're just
missing some key piece of information right now.

Basically the region array is processed, and the data from the accumulation
buffer where we render is now copied into the framebuffer depending on the
tiles specified in the tile list. This isn't full 'tile-based rendering' as
that would require more work on the preprocessing side, and writing out the
data pointers and data in real formats, however it's a step in the right
direction.
Currently only 565 formats are supported for both framebuffer write and
framebuffer read. The accumulation buffer is alwys 8888, data is converted
down to the specified format. The real accumulation buffer is 32x32 and
filled per tile, ours is still full screen.
The video update now just displays the framebuffer using the framebuffer read
parameters specified (again only 565 is currently supported) This allows the
Atomiswave bios screens and the rendered output to co-exist.
