I want to report another bug I just found. If you load kof2001 on AES mode, the title screen shows messed up graphics:



It shows correctly on kof2001h, though. But what could be causing the bug on kof2001?

That's not a bug. That games AES menu was not finished in the MVS version.

Oh. Thanks for the correction.

Is this the only exception or are there any other NeoGeo games with the same problem (unfinished AES in the MVS version)?

Small bit of news:
Alien Sector/Baraduke: fixed the dac speech
Pac-Land: fixed the missing sounds

Regarding the M65c02 subcpu's in the (older) Seta driver - games like TwinEagle, Caliber 50 etc:  I tried, and tried, and tried... and tried.. but can't get the subcpu to work.  At this point, I don't think they will ever work properly :(  On the bright side, they probably aren't games that anyone will ever miss... it is certainly a challenge that has outdone me.

that's all for now,

In any case, thanks a lot for your hard work! :)

PS: can you add the latest "rotary code" to Caliber 50? In the current version it's impossible to rotate the player character...

Thanks, btw, I'm not doing anything else with calibr50 until the subcpu works.

I've been wondering, what's the current status of spu emulation on system16 ? Some people mentioned that libretro-fbalpha have "garbled sound" on golden axe, while libretro-mame2010 (which is a port of mame 0.139) doesn't. Is that an issue in my libretro port or is that a known issue for this game ?

Edit : i think i've got my answer : i need to set samplerate to 44100 ?

I want to report another weird thing I found. The game is Nam-1975 (NeoGeo) - I made a short video about it:
https://www.youtube.com/watch?v=-aOG1QzsQA0

At 0:42~0:48, can you see a couple odd lines appear and disappear suddenly? Not sure if it's normal of the game or not, but it looks like a graphic glitch to me.

It sounds perfect on my side :)  btw, a lot of soundcores need 44100 or 48khz to operate properly.

Hi, I played it here on my side and I don't get those lines. I'll need a .fs and your current fba ini file to check it out.

I tested the game, but (like dink) I didn't get those lines... did you try the game with different FBA settings?

I didn't get those lines either on fbalpha-libretro, so it is probably a graphic driver / blitter / shader issue ?

@dink : thanks, are there soundcores that needs 48000 instead of 44100 to work properly ?

As far as I know, the sample rate needs to be set to 48 KHz in all Jaleco "Mega System 1" games (megasys1.c) and in Konami's Contra (probably there are also other games with this "restriction").

Thanks, out of curiosity, is there any reason why someone with a 48kHz capable soundcard would want to run fba with a samplerate below 48kHz ? Resources ? Games that won't work well at 48kHz ?

There's a few later konami games like xexex, moomesa, etc. all jaleco megasys1 games & contra run at a slower tempo w/41khz - (but I sorta like that personally, so I leave it set at 41khz).  The later konami games have a patch to run fine at 41khz.  Maybe it would be best to default to 48khz? hrmm..

Also the game Ken-Go (Lightning Swords), some of the sound effects don't sound right with FM Interpolation set to off.  my suggestion is to default that on.  re: sample interpolation, leave that at the lowest setting (aka set at 2-point interp.) because it causes clicks in some games with a msm6295 (boogie wings comes to mind here).
