My fix is a bit heavy handed. The real access violation happens in update_digital_joysticks() after the comment "read all the associated ports" and before the next comment
01517: all atarigt.c drivers: Assertion

Converted Centipede, as an example.
To define a scanline timer, use something like this:
MDRV_TIMER_ADD("32V", SCANLINE, generate_interrupt)
MDRV_TIMER_SCANLINE("main", 0, 16)
The first number is the first scanline the timer will fire on, the 2nd number is the increment.
So in this case, the timer will fire on 0, 16, 32, ..., 224, 240, then wrap around
because the screen is defined as 256 lines high.
The current scanline is passed to the callback in its 'param' argument
This driver is creating bitmaps in DRIVER_INIT, which is not the best practice, and in fact, it broke as machine->primary_bitmap is not initalized yet.
Subject: small fix to cpu.mak
Attached please find a small patch to include M68000 CPU only when you're
compiling a build with the M68K. this is needed to e.g. compile tiny
builds .
Created MACHINE_START( asuka ) to configure cpu2 banks with memory_configure_bank(),
All drivers support save states, with the exception of cadash and clones, the background does not load properly. I'm not familiar enough with taitoic.c to make that happen.
Subject: punchout.c inputs/dips
punchout.c:
-Simplified input definitions
-Improved dip switches
-Added dip locations
Note:
punchout and spnchout had an extra 5th PORT_START, was it correct to remove
those?
If not just drop me a note and I'll resubmit the patch.

This time, it's phase 2 of the Deal 'Em input changes (these work well
with the default cabinet type, I need to do some conditional input work
to fix them fully), and also a conversion to the resnet code.
Unfortunately, this still doesn't fix the apparently needed transparency
(the apostrophe and Zenitone logo on the title screen should have a
green background, and the black rectangle at the bottom should read
(C)1987). I also tidied up the memory maps, but have been unable to
reproduce the assert bug relating to VBLANKs, so I'm unsure as to
whether I've fixed it or not.
Subject: patch for SVP (Sega Virtua Processor) emulation
hello,
this patch adds support for Sega Virtua Processor, to run
Genesis/MegaDrive version of Virtua Racing, intended to be used by
MESS. It consists of a CPU core SSP1601, and updates in megadriv.c:
* SSP1601 replaces SSP1610, as it has been confirmed by Stiletto and
other sources that SVP actually contains SSP1601. The current SSP1610
is placeholder only (nearly completely unimplemented) anyway.
* Changes in megadriv.c add a new driver for Genesis/MegaDrive+SVP
combination, also add SVP memory controller logic and memory map.
The diff has already been reviewed by Reip and SSP1610 removal was one
of his suggestions (SSP1610 is not used by any drivers).
mame/drivers/superqix.c
mame/video/superqix.c
Changed vblank interrupts to 3 to fix screen drawing issues.
Use memory_configure_bank() to configure memory.
Added save states.
Attached is update for Merit hardware based on V9938 (CRT-250 and CRT-260 - meritm.c).
New playable games:
Pit Boss II
Super Pit Boss
Pit Boss Megastar
Megatouch IV
Megatouch IV Tournament Edition
Megatouch 6
