- 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

I've added dipswitches for the coins, you can now select between 1 and 6
minutes per coin.
I've also added information about the original games that these have
been bootlegged from.

Exzisus (Japan, dedicated) [Stefan Lindberg, Phil Bennett]
(This is now the parent set. The existing set becomes exzisusa)
Added correct ROM locations for exzisus and flagged exzisusa b23-03.14l as BAD_DUMP. [Phil Bennett]
- implemented reset for TMS5220C if /RS and /WS are pulled down together
- Inserted LNs email and corrections as comment into source
- Created a TODO section.

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))

- 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.
