Edit : i tried looking through the issues you mentioned in that file, i probably missed a lot but noticed those :

Wow, this is great. Sorry I didn't respond sooner. Been unavailable. Will review.

Edit2 : what's the issue with pleiads color on fbneo ? i compared it to a few videos from the pcb on youtube, colors seemed to be accurate

I see the same. Some PCB videos showing the black/yellow/green aliens.

There are others with magenta.

EDIT: Try this video:

One more:

I used to play the Centuri version of Pleiads when it was new and in arcades. In the first level, the aliens that fly around are supposed to always be magenta and never black. They appear correct in their "ball" state and when they are building 'bricks", but when they are flying, they are black, which is incorrect. The "SCORE AVERAGE TABLE" that displays during attract mode demonstrates the issue perfectly:

Ironically, the same flying aliens in the Spanish version (pleiadss) look closer to what I remember. Still wrong, but closer:

@barbudreadmon regarding the fix list above:

mgakuen (freeze) => fixed CONFIRMED FIX!
bradley (freeze) => turns out this one's emulation was never finished, so it was supposed to be marked as not working CONFIRMED PROPERLY DISABLED
hydra (accelerator bad sensitivity) => i can't reproduce, is it happening too if you remap to a non-analog button ? User error. Default Acceleration appears to be 200%. Set to 100%
luctoday (180 deg) => fixed CONFIRMED FIX!
mtlchamp (run too slow) => performance was improved, not sure it's gonna be sufficient for pi4 though CONFIRMED FIX! Fine on Pi4
pdrift (doesn't accelerate) => i can't reproduce, is it happening too if you remap to a non-analog button ? User error. Default Acceleration appears to be 200%. Set to 100%
robowres (no punch controls) => weird, but we might be misunderstanding something about controls in this game, tutorial seems to say grab is same as punch, and grab seems to work No issue/User Error. Understanding buttons are chorded
sdungeon (dual stick, not working properly) => oops, fixed CONFIRMED FIX!
spacecho (crash when shooting a ship carrying a human) => fixed CONFIRMED FIX!
tdpgal (180 deg) => fixed CONFIRMED FIX!
victoryc (180 deg) => fixed CONFIRMED FIX!

Amazed to see so many fixes get addressed so quickly (and I didn't even request or properly post in github).

The only other issue I've seen (via list):
Drakton (drakton): No audio in lr-fbneo

Thank you again for re-introducing me to lr-fbneo and for all the great fixes.

For that one there won't be a fix soon, FBNeo doesn't have the emulation code for its sound cpu (MB8884), which is also why dkong, which run on same hardware, uses samples.

There are some amazing people in the team

2 other issues from your list were fixed :

• digdugat was added
• dodgeman should now have more proper colors

For pleiads, i believe the running version is same or close to this video :

(it's from an actual pcb on the right)
Different versions of the game seem to show different colors, the one you are looking for might be a clone, did you try all of them ?
The thing with your videos is that none of them clearly state that they are running on an actual pcb.

Yes, tried all of them. The closest was the Spanish version. All others feature the black flyer. Thing is, growing up, I'm certain that the colors were magenta. While it's possible there were color variants in the 80s, I'm sceptical.

[Theorizing] Wondering if the base ROM set is inaccurate. Also wondering if PCBs shown in videos are using EPROMs based on MAME sets and are not original. Could explain.

The fact that no set yields the proper colors that I'm familiar with (for any version of MAME) suggests either faulty emulation or bad color palette in the ROMs themselves. One or both must be true, since I've seen 3-4 of these in the 80s and they all looked the same.

Not a major issue, but I don't believe the original have intended to have that shape, only to make it black/invisible and have it clash with the other states.

Very odd.

There is no way to know if one of your videos is from an actual arcade pcb or not, generally a youtube video of an arcade pcb would mention it in the title or show the pcb itself, that's not the case here.

Edit : actually pretty sure none of them are, the 1st and 3rd with their static screen looks like capture from an emulator, and the second one (which is the one that looked most like a pcb) shows a menu with games like 1943 before launching pleiads

Very good point. I suppose I can sum up my thoughts like this. Pleides emulation is very good. When it was first emulated in the 90s, I remember how happy I was to see it, because I played it to death. It had the magenta flyers, but at that time, the MAME What's New informed colors were not accurate, but they were close to what I remembered.

Time passed and the ROMs/driver were updated and the flyers went black. I should have reported it back then. I kept thinking they would change in a future update, but they never did. I've tried all the clones as new versions of MAME were released.

So I admit it's possible there original PCBs had the pallette I'm less familiar with, but the fact none have the pallette I remember suggests something is wrong either with the driver or with one or more of the ROMsets, it it's also possible the common version I remember was simply never ripped. Doubt the last one is true. The machines were in multiple locations in Silicon Valley and I would think they would have been ripped by now.

Regardless, not looking for you to find the solution for me. Lol. Appreciate everything you're doing for this community.

@roslof Wondering if there could be something unemulated with the video signal processing, that could explain why my video has the same colors as fbneo, since the signal seems to be converted for display on lcd.
You should bring up the issue at MAME, they might know something.

You're ain't kiddin'.

Confirmed, Dig Dug Atari is working/supported!
Dodgeman colors look good!

[barbudreadmon]

@roslof Ok, if you find any other issues, feel free to send a report, you can also try asking for specific clones/hacks support since they are generally easy to implement. It might also be worth mentioning new games are supported almost every weeks, you can generally find more about them by browsing our forum (especially dink & iq_132's topics, they are the 2 main devs)

Edit : bradley is now available and working !
