Re: Ap2000 signs of life Golden Child 09/20/20 09:59 PM

I managed to get something working that would save the printer output bytes to separate files so you could launch a viewer on them, like gv for postscript output.

A delay of 30 seconds will separate files.

lp0 = manager:machine().luaprinters[1]

function feedchars(ch)
local idleflag=0
nextchar = lp0:getnextchar()
if nextchar >= 0 then 
  if f == nil then
    filenamecount = filenamecount+1
    currentfilename = filenamebase..string.format("%04d",filenamecount)..".ps","w")
until nextchar < 0
if idleflag==0 then
  if f~=nil then
    if idlecount%(60*5)==0 then print ("idle: "..idlecount/60) end
  idlecount=0 -- reset idlecount
if idlecount > idlewaitperiod then
  os.execute('gv "'..currentfilename..'" &')
  print('gv '..currentfilename)

function framedispatch() for i,j in pairs(dispatchlist) do j() end end

idle: 5.0
idle: 10.0
idle: 15.0
idle: 20.0
idle: 25.0
idle: 30.0

Very cool... thank you!! These will be interesting to do... can't say "when" at this point, but it's on the list.

Re: Android Pause/Resume R. Belmont 09/18/20 03:55 PM
Android isn't officially supported, especially in terms of phone-specific stuff like suspend/resume and backgrounding. I'd expect SDL2 to handle at least some of the details there but there's probably other things that need to be done.

I've replaced the filter capacitor on the P2000, and it's back to running smoothly again.

Nice graphics for the time:

Quoting a vcfred thread: "The machine has a CPU board with a separate "terminal" board that is connected to the CPU board via a TTL level serial link, so the display looks like a dumb terminal to the computer."

This guy is repairing his terminal board, some useful information there, but there are full schematics in the manuals I posted.

Re: Get a seg fault only with Odyssey2, only in Ubuntu hap 09/09/20 10:50 AM
Crash bug was fixed a week ago btw. And for anyone clicking this thread, here are some bonus screenshots laugh

Some minor bugs remain, but overall the emulation is very good. The bug that annoys me the most is in Backgammon. It does multiple screen updates but (even according to the disassembly) it never increments the sprite/char Y registers.

Will consider a video when I'm happy with the emulation, want to get a little more performance out of it.

Just to clarify, if you use -aviwrite and also specify -noafs, then the resulting video will play back full-speed regardless of how slow the emulation is during recording.

Ultimarc Aimtrac on MAME - Ubuntu Simon Foote 09/07/20 09:08 PM
I recently purchased an Aimtrac lightgun and I am having massive issues getting this to work in MAME running on Ubuntu.
I am using the latest build of MAME (0.224) and Ubuntu is running on a PC, not a Raspberry Pi or anything like that.
Using The Ubuntu Windows desktop The gun works as a mouse. Other than it's not very accurate, because the calibration utility doesn't work, it works fine.
In MAME itself, if I press TAB to go to the controller options, that sees it as Mouse1, which exactly how it picks up my trackball, which works perfectly in gun games and also my Spinner.
However, the only thing that isn't right with this is, when configuring mouse devices, depending on what way you move the device, you get mouse X or Mouse Y. With the Aimtrac, Whatever way I move the gun I get Mouse X & Y at the same time.
I'm guessing, as a result of this, when I try to use the Aimtrac in a game, as soon as you bring the gun into view of the sensor, it just drops the crosshair into the bottom right hand corner of the screen and will not move.
If you take the gun out of sight of the sensor, you can move the crosshairs with the spinner or the trackball no problem.
The other thing I've found is, I'm using EmulationStation as part of RetroPie, so even though I'm not using it, I have LR-Mame installed. If I open up a shooting game with LR-MAME2016 instead of standard MAME, the gun works! However, my spinner doesn't.
I've tried following the steps under using a lightgun in Linux , in the official MAME documentation, but that didn't resolve the issue. In fact it introduced some new problems, for example disabling the buttons on my Ultimarc Ultimate IO controller.
A friend of mine also has two of these guns running on a similar set up, but using Debian rather than Ubuntu and they are getting exactly the same problems as me.
Any help, solutions or suggestions welcome as this is driving me mad!

Re: Electron WIP Vas Crabb 09/07/20 05:20 PM
You can call set_maximum_quantum in as many places in the machine configuration as you like, and it will take the smallest one and use that as the longest scheduler timeslice allowed for the machine. Whether you set it or not, it will never use a timeslice longer than 1/60s as that’s hard-coded as the longest allowed timeslice in the scheduler itself.

I don’t particularly like the “perfect quantum” configuration because it’s kind of misleading. It doesn’t necessarily give perfect interleave on the device you set it for. What it actually does is query that device’s device_execute_interface for the minimum machine cycles per instruction, converts it to clock cycles, and multiplies by the device’s configured clock frequency to convert it to a time. Then if that’s smaller than all the values set with set_maximum_quantum, it will use it as the longest allowed timeslice. It may fail to give perfect interleave on the device if some other device executes an instruction that takes longer than the desired timeslice length and it needs to catch other devices up.

(There’s nothing special about the “perfect quantum” device – you can get exactly the same effect by using the same calculation and calling set_maximum_quantum with that value.)

Re: BletchMAME 2.0 Bletch 09/03/20 10:37 PM
Yes, there is a LUA plugin ("worker_ui") distributed with BletchMAME that essentially provides what is sort of a hybrid between a command console and an RPC-like mechanism. Its not using sockets, but rather standard IO - meaning that you can execute MAME with that plugin and control MAME using the same facilities BletchMAME is using.

The FDEB is in the tx_videoram region which is as you guessed out of range for the debugger cheatfinder. It's a bad case for the lua finder too because it won't automatically search it although it can be done. Here's a link with some info .
