Great release as always!

I tested a bit the libretro .43 core and found a small issue. Cyvern (Kaneko system) has very choppy video with "Speed Hack:On". The framerate number shows no fluctuations and the sound has no issues, but the image is slightly stuttery every two seconds or so. Before, with the hack, it had perfectly smooth image with some missing and delayed sounds and music.

Also, the buttons seem to be inverted/differently placed (what used to be fire is now nothing, what was nothing is now bomb and what was bomb is now fire....if that makes any sense), with no option in the ""Core options" to set them to either Gamepad or Arcade, like before.
I guess i could add a third option in the speedhack dipswitch to enable the old "cps3speedhack", saying "some missing and delayed sounds and music" is a big understatement though : the sound was a complete mess.

About the lr-fbalpha mapping, it was migrated to "Quick Menu > Controls" a year ago. There is no equivalent to the old "Arcade" setting though, because it relied on not having your retropad mapped as documented there, which is bad thing.

Ah i get it.

Really, don't bother adding the old hack. I mean, one could use the old core anyway for a different experience.

I guess i'll modify the touch controls to keep the button placements 😊

More bug reports, please!!
I saw a report this morning about green beret & rush'n attack running extremely fast since last release, considering they are both from the same driver there could be some truth behind this issue, i didn't have time to test it before going to work though.

gberet is OK here, I did the side-by-side comparison test :)

gberet needs a re-write in a bad way. One of these days i'll get around to finishing that.

Since there were no changes to the driver, I have a theory:
first: this was probably always broke for the reporter, unless there was a core change to the fps handling in retroarch/libretro etc.
second: gberet runs at 30fps.  If the system they are running on is 60fps only, or fps handling is broken somehow, the game will run twice the speed.

Yeah i had the same exact problem on the xbox with Green Beret / Rush'n Attack another also affected was Ironhorse, so it's
definately a platform specific issue, i have a workaround however to bring the speed down to the correct level for the above
games via iq_132........

@barbudreadmon i'll push a commit later which should sort this.

Not actually a bug (and not worth its own thread, I guess), but something that everyone probably already knows about: the game filter categories are kind of arbitrary (which companies are listed or not, and some overlap, too). Also, games are not always listed under the most appropriate filter (for example, many are lumped together in Misc pre 90s rather than being put under the concerned company).

Are there plans to overhaul this, maybe using game metadata instead?

Stifu, thanks for the feedback.
This is a tough one, and there is definitely room for improvement.  There are no plans really, but if we notice something out of place, we'll try to fix it.

Completely arbitrary. I would not be against moving everything into simply drv and anything that doesn't have game structs into some other directory. The down side is that we'd lose all the history on those files.

Thanks for your replies.

I noticed something that seems weird to me. I'm under the impression "gprider" and "gpriders" (clone of gprider) have the exact same 30 files, with the same crc. I noticed that because Romcenter tells me I have "gpriders" even though I only have "gprider".

The parent is the dual board, and the clone the single board. The roms match MAME, however, we don't emulate the dual board so they are effectively the same set.

I must be cursed or something with arkanoids, i picked a random version (arkgcbl), and ended up with the same "bad hardware" screen i had with arkatour on .42, except i get it later (after intro).

On a sidenote, the gberet issue was fixed (basically, the timings i computed for the libretro api were wrong because nBurnSoundRate/1000 was greater than nBurnFPS/100).
