Couldn't we just fake it with a simple 'stupid' R/C lowpass emulation in the brightness output? i.e. an accumulator which accumulates at a configurable rate when output is on, then leaks out at another rate when it is off?

Yes, something simple. Let the outputs from MAME's side be the same as now of course (1 or 0), and let our artwork side handle the decay stuff.

I got Entex Baseball 3 today. It's got a TI 28-pin SDIP labeled
6007
MP1204
MSL^8014
From the wiring, I'm guessing it's a TMS1100.
Entex Baseball (1) should get here in a few days.

Thanks! I'm not sure how I missed that- I just fired up the comparison program again and it found it, so I must have skipped it for some reason. There are a few partially obscured bits that the program doesn't like, so I skip those, but $D1F is perfectly clear.

Good news sean, if that's a TMS1100 it would make emulation doable I guess  Curious to see if Baseball 1 will use the same chip. Not really related to this, but could you please confirm what's the CRC32 for your latest Pinball dump for Microvision? I just realized the rom bundled with Paul Robson's emulator doesn't match the one in the MESS software list. I know you corrected an error you found at a later point, but I'm not sure which one is the correct version anymore.

The latest pinball.bin I've found is dated 3/17/2014 and has a CRC of 906544EA.
I need to double-check all of those MicroVision dumps just to be safe.

Then the one in the software list is the old one as I was suspecting, Paul Robson's emulator contains the correct version.
Someone needs to correct this.

Speaking of that, Sean do you have good quality die pics of your Microvision games(ROM area especially)? And TMS1000 Simon?

Over the next couple of weeks, as I get time, I'll find the Microvision ROM pics and upload them.
The Simon ROM pic is already out there: www.seanriddle.com\simon_acid_rom1280.jpg
