Goodbye fbalpha, welcome fbneo

@g30ff that's not a bug, i remember that hack used another button for p3 special (probably p3 coin)

G30FF

@barbudreadmon Aah. My mistake then. I went and read the development thread on RHDN more thoroughly, and now I understand. Thank you!

barbudreadmon

@g30ff out of curiosity, i checked that game and noticed p3 coin doesn't seem to add any credit, if it's only used as p3 special then i should probably map it directly as such, or am i missing something ?

G30FF

@barbudreadmon Apparently that's by design. I went to check the RHDN thread about the game, and found this comment from the hacker:

Arcadez - Thank you for supporting ffae! P3 coin doing nothing is not a bug, it's technically p3's button 3. For various reasons we decided not to implement p3's coin button, primarily because on a real arcade cabinet you'd likely have two coin mechanisms and coins are shared in final fight. It was assumed users would just double map one of the other coin buttons to p3s select button.

So it seems that P3 Coin is actually P3's Special button, and P3 just does not have a coin button.

On an unrelated note, and I'm not sure if this is a known issue or not, I tested out bucky in lr-fbneo, and when it boots up, the screen is upside down, ROM N2 shows as BAD, and the game never moves past the RAM ROM Check. Clones seem to work, like buckyea. Again, not sure if this is a known issue, just wanted to mention it.

Ok, i'll change default mapping then, thanks for the feedback

I can't reproduce this, the only thing that comes to mind is that your eeprom got corrupted or something, try deleting it (bucky.nv, i believe FBNeo eeproms on RetroPie are saved in a fbneo subfolder of the rom folder), i've seen similar issues happening from time to time with konami games.

G30FF

@barbudreadmon I deleted bucky.nv, and the problem did indeed go away. The game works just fine now. Thanks for the info!

Support for nintendo VS was added, note that we don't plan on supporting the MAME multi-files romsets for those, instead we use the single-file romsets which are also supported by a few NES emulators.

G30FF

@barbudreadmon Very exciting news! I'm looking forward to trying them out! Sourcing the roms for this set was a challenge, but I've managed to get them together. So far I notice four VS System games (that I'm aware of) are missing from the dat, so hopefully those will get added in the future. I'll test them out when I get the chance.

barbudreadmon

@g30ff Only the support for "Vs. Unisystem" was added, support for the few games running on "Vs. Dualsystem" (2 linked nes) wasn't implemented, i doubt it will in the near future because it'll require some major rewrite of our nes driver (current driver doesn't allow to run 2 nes instances at once).

G30FF

@barbudreadmon Aah. I actually didn't realize those were separate things, but yeah, all of the games I see missing have two screens. Thanks for that!

I've tried out all of the games, and these are the only issues I noticed.

vstetris: Player 1 controls don't seem to work. If I start up a 1 player game, I have to set my input to player 2 for the game to register my inputs.
vsfreedomforce: I got a game over, and the game hung. It didn't take me back to the title screen. However this only happened once, and I couldn't get it to happen again.

Overall, excellent work!

barbudreadmon

@g30ff Thanks for the reports !

I fixed the issue for vstetris.

For vsfreedomforce, are you talking about a black screen where you can still move gun cursor ? Did it happen right after inserting coins ? I got a bug like this, but i'm not yet sure what this is about, it could even be something happening on original game.

G30FF

@barbudreadmon I tested the fix for vstetris, and it works now!

For vsfreedomforce, it was the same experience you described, but after the game over screen disappeared, not right after inserting coins. Not sure if it's a bug with the actual original game or not. Sorry I can't be more helpful, I wasn't able to reproduce it after the first time it happened.

barbudreadmon

@g30ff most likely, the random issue with vsfreedomforce is fixed.

G30FF

@barbudreadmon Updated. If it happens again, I'll let you know.

Two Konami beat 'em ups exhibit fairly isolated performance issues on my Pi 3B+:

asterix becomes stuttery in level 2, maybe due to the background effect of air swirling in the heat

moomesa does the same when the attract mode gets to a boss fight with a floating platform

Apart from these instances, the games seem to run fine, so are these emulation issues, or is the 3B+ just too slow and obsolete by now?

barbudreadmon

@weirdh those are called raster effects and are usually quite demanding, their proper emulation is one of the main reasons recent'ish arcade cores are slower than the old ones

WeirdH

@barbudreadmon Okay, good to know, thanks. Will a Pi4 have trouble with these effects as well? Or is it all different on a per-game basis? I remember tophuntr having issues with the bonus level transition effect on Mame2003-plus, but it works fine on FBNeo.

G30FF

@weirdh Tried it out on my Pi 4, and I don't see any problems with the games you mentioned. I don't have any overclock settings, and am using default FBNeo settings for them. Most games I've tried work in FBNeo on the Pi 4 stock, some (like Sega system 32 games) require a frameskip setting of 1 frame enabled to play at full speed, and there are a few games I've tried that are just too laggy to play even with frameskip, but work in lr-mame2016 instead (for example, gametngk and tetrisp).

Hi.

Is it possible to load lua training scripts?

Here's a collection for many supported titles:

barbudreadmon

@addison No, that stuff only works on FBNeo standalone (windows), RetroArch doesn't offer any kind of support for lua.
