News / Re: PGM2 is working

Please add PGM2 in Fba  :biggrin:

Thanks, it works, it seems i can't get the analogs working at the same time though. I guess i'll have to implement some kind of mecanism to switch between different I/O board setup. Best case scenario would be to directly load mame roms and autoconfigure this from their name (at the moment, reicast loads an arcade game from a file containing all the decrypted roms concatened, and that's kinda annoying because we can't use mame roms directly).

I wonder if you could try changing random / seemingly unused input bits until the 3p/4p inputs show activity?
That's an interesting idea, i tried setting the bit indicating the number of player in the I/O board to 4, and ended up with this :

Inputs are broken now, but perhaps i can figure out something.

Unfortunately I can't find anything about the internal workings of this IO board.  :(

FBA Discussion / Aspect Ratio Problems
« Last post by dojima on July 08, 2018, 06:59:20 am »
Hello, I've been using FBA to play Street Fighter III:  3rd Strike.  From my understanding, this is a 384x224 resolution game that's intended to be displayed at a 4:3 aspect ratio.  No matter what I do, however, I can't manage to get FBA to run it at this aspect ratio.  It seems to prefer a ≈1.37 aspect ratio, specifically 307x224 in 1x mode.  FBA correctly detects my monitor's aspect ratio, but even manually selecting different options doesn't work.

I found another thread here where someone appears to have the same issue.

Thanks for any help.

edit:  After testing it again, I've determined that it runs in the correct aspect ratio in fullscreen mode, making the situation even more confusing.  The game also runs in the correct aspect ratio in windowed mode when using the FBA Libretro core within RetroArch.

Thanks :)

I guess no one knows about the Capcom Naomi I/O board ? It seems to be needed for 4P games.

While i didn't find anything about it in Naomi MAME driver, i see here and there that it can be used in other JVS hardware (they even mention CPS2/CPS3), so perhaps it is known under another name in MAME's sources ?

Let me know if you learn anything about it.

FBA Development / Re: dink's FBA Development & Fixes thread

Dragon Gun
Due to the sheer unfairness of this game, the game didn't get as much testing as it deserved.  A quick trip to the service mode settings and putting the game in Easy mode solves that problem, and it turns out being quite a nice lightgun shooter.
Anyhow, a bunch of video & a game-related issue was fixed:
Ability to fully beat the end boss
Neat masking effect with the fire/dragon as the titlescreen comes in
Raster drawing to stretch the tilemaps (mostly stage 3/water level)
ugly black rectangle in the water as the stage 3 boss approaches & the water splits

There are still a couple minor sprite:sprite priority issues that I can't quite figure out, but they barely affect the gameplay.

best regards,

Great job :)

I managed fixing both issues :biggrin:.

Hi everyone,

I thought i would ask here, since i don't know any other people who are good at emulating arcade systems.

I've been trying to help with https://github.com/libretro/reicast-emulator lately. This is the libretro port of a dreamcast emulator, and it runs naomi/atomiswave games too. Compatibility is great (actually, greater than the standalone version), there are not that many games that won't boot or have graphical issues with the latest builds.

However, there are some issues with input :
- analogs don't work
- 2nd player doesn't work in some games

The issue with 2nd player is particularily weird, from looking at https://github.com/mamedev/mame/blob/master/src/mame/drivers/naomi.cpp i get the general idea that games like MVSC2 or DOA2 (where 2P works in this emulator) share common input mecanism with GG XX accent core and Akatsuki Blitzkampf, however 2nd player doesn't work with those 2 (and probably some other).

Any advice on what we could be overlooking would be really useful :).

Edit : i think i got a general idea of what is wrong, see https://github.com/libretro/reicast-emulator/issues/115 if you are interested or want to help.
