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 ?


Only if they're weird like me and like certain games to run at a slower tempo. :)

So, if I understood well, the best audio setting should be:
48000 Hz samplerate;
2-point 1st order sample interpolation;
4-point 3rd order FM interpolation;
Buffer size "8".

After wrestling with the Seta m65c02 subcpu for Caliber 50, DownTown, Thundercade, Twin Eagle, Arbalester, MetaFox (and a few others) for ages, I finally figured out that the bug was in our 6502 cpu core and not the game emulation.  Now that has been cleared up, these games are finally fully playable in FBAlpha!
Also, Caliber 50 and DownTown have the same excellent rotation code that Midnight Resistance, Heavy Barrel and the SNK Games (Ikari, TNK3, Gwar, etc) - makes playing them in emulation very nice.

This was supposed to be done a year ago (a year and 2 months to be exact), so my apologies, Zazzone, for your report getting lost in the crazy space called my head. ..  It would appear like several video bugs had been squashed here in Rolling Thunder, but really, just the layer offsets needed to be tweaked.  SkyKid DX and Hopping Mappy had some layer offset issues as well, but they were hardly noticable.

Let me report a few bugs I found.

Lightning Fighters / Trigon
The game looks too dark on fba, to the point it can get a little hard to play on some parts. The colors show correctly on mame:

FBA


MAME



Thndrx2j (Thunder Cross II JAA)
Game won't even load at all. It works perfectly on mame, but on fba it shows an error on the romram check screen, making it impossible to go further:




Xexex
This one is a little hard to explain, but basically, the opening cutscene doesn't animate correctly. The audio is also pretty bad (the princess' voice can barely be heard, etc). I made two comparison videos:

xexex FBA: https://www.youtube.com/watch?v=0ypdOk-5jmE

xexex MAME: https://www.youtube.com/watch?v=3HbC_yir49c

Thanks for the reports!

Thndrx2 is now fixed, I'm afraid Xexex's intro is currently unfixable unless iq_132 has any ideas (I tried a few times and failed).  It's probably related to the k056832 priority issue that is also plaguing a few other games (mtlchamp, yeesh, I forgot the others.)

re: lightning fighters, neither MAME nor fba's colors for this game are correct - look at a pcb version of this one :)  Personally I like our darker palette for this game, MAME's is definitely way too bright here.  But if you really are going for a "correct" look, then the pcb is the only option IMO.
