read/write functions and various other types of functions. Introduced new
structures and macros to make this possible.
To take advantage of this, a device must change its interface to replace and
read/write callbacks with the new devcb_read/write structures. During device
start time, the device then uses this new devcb module to resolve the information
in the devcb_read/write structures into a more efficient form. When the device
needs to call one of the callbacks, it uses the inline devcb_call_read/write
functions.
Once a device has defined its callbacks as devcb_read/write structures, users
of the device must use the DEVCB_* macros to specify the type and information
about the handler to use:
DEVCB_NULL = no handler
DEVCB_HANDLER = a standard device read/write handler
DEVCB_MEMORY_HANDLER = a memory address space read/write handler
DEVCB_DEVICE_HANDLER = a device read/write handler for a different device
DEVCB_INPUT_PORT = an input port
Converted the 8255PPI device to use this new structure, and updated all users
to use the DEVCB macros, removing some unnecessary trampoline functions along
the way.
I didn't get around to documenting this one in full detail, but at a quick glance it appears the region works in the same way. ie, the first byte of one of the roms is 0x01 instead of 0x00.
I've also documented how the region works on Batrider based on these sets.
----
I can't get him to provide any further proof of ownership of this stuff, and I think pressuring him for it is more likely just to piss him off, and result in no further contributions (he already didn't respond to my last mail a few months ago, so I'm sending this now..)
===============================================================
I'm not quite sure about aerfboot,sound seems s****y but reasonable (i.e. plays different stuff than the original sets).
Can any okim6295 expert look if I did an error on the sound banking/soundlatch sides?
also reworked the code a bit to make it harder for somebody to break it in future. (removed the config table & moved keys to driver inits, define region sizes, allocate memory in init for CD based games.)
should be no functional changes, although it might be a fraction of a % faster due to there being less region lookups.
new clones added
----------------
Noboranka (Japan) (NOT WORKING, undumped 8751 MCU)
(old bootleg set is now a clone)
also fixed
"02873: Many sets in system1.c: Missing text layer"
using the method Kale posted
and renamed some functions in drivers/system1.c etc. so it's clear that they're used by the bootleg 'nobb' only, rather than system1 in general.
New games added or promoted from NOT_WORKING status

Here we go.

Hi. Actually it was a my mistake removing the cpu_eat_cycles thing. I was convinced it caused some sync issues but after some intensive testing I can say for sure it's right. Re-implement it makes the game run at full speed and there are no other problems. Sounds are in perfect sync with video. I'm sorry for my first wrong submission happened in 0.129 where I replaced this speed-up with a wrong one.
Regards.

Changed oki xtal to 400khz, verified on pcb. Unfortunately I couldn't verify the main xtal which was missing on my pcb.

Subject: stepstag.c
-added custom 3-screen layout;
-added recently dumpped game "Stepping 3 Surperior"(incomplete ROM/CHD set);
The game name of "stepstag" romset is actually "Stepping Stage Special", not the original "Stepping Stage".
this clone fell through the cracks, I was checking my misc rom dir and there it was ;-)
