Still broken in MAME version 0.273.

I've made my own fork of this version of NABULIB (currently most recent), for NthPongWars customisations (like removing that unnecessary 2K text buffer if I need memory space). But for now, I've just put in the (void) function declarations from LinuxPlayGround's fork (minus ones where void was added ...

Sounds like failing electronics which only work when warm. You did fix the fan, and more relevantly reseated the chips. Try reseating them again.

Also the circuit board may flex when warming up, affecting connections. Does it crash if you manually flex the board while it is running? Make sure to ...

I tried the DEBUG_VDP_INT option in NABU_LIB, which flashes the Alert light when you miss a frame. It has a logic bug and leaves the light on all the time!

To fix it, add a "vdpIsReady = false;" right after your call to vdp_waitVDPReadyInt(), because that function forgets to reset the flag after ...

I can confirm that MAME version 0.270 also works. Using Fedora 41 Linux.

I started up MAME today (finally some time to do NABU programming), and it doesn't work, giving Adapter Failures on the NABU side and NPC disconnected on the server side. Turns out MAME version 0.271 on Linux (Fedora 39) doesn't communicate with the RetroNet server over TCP any more. I was able to ...

I was looking for a sprite and font editor for my NthPongWars game (just starting out, needed some art to draw on screen). I had a look at the Quiver https://nabu.ca/downloads-quiver and found a few, and ICVGM seemed nice and works in Windows 2000 (in a VM under Linux). It edits fonts, screens and ...

Great, thanks! Nice to see the possible date format codes are in the comment, and there are ones for time zone and year so UTC time stamps are possible.

I was thinking of putting in a date stamp for people getting high scores in a game, but noticed that there's no way of finding it out. CP/M 3 has date and time, but we're using 2.2 which doesn't. Also nothing in NABU-LIB. Was there something in the original NABU OS that did it? Or should it be done ...

Actually, even cheaper, just ask around and see if anyone has already dumped that EPROM chip. It has a NABU part number too, which would be worthwhile searching for.

Then you can find out the details about the microcontroller chip, a Motorola SC87253P, which I assume gets its instructions from that ...
