@barbudreadmon (gasp) Outfoxies is supported!?!?!? (runs away to update)

saccublenda

@iandaemon Yeah. Choppier than with lr-mame2003-plus, but it works.

IanDaemon

@saccublenda I see that now. The 3B+ just doesn't have the power I guess.

saccublenda

@iandaemon I'm on a PI4.

IanDaemon

@saccublenda It's a 2D arcade game using sprites so I can't imagine it requires that much "oomph". Yes, there can be a lot going on at any one time, but still.

barbudreadmon

@saccublenda @IanDaemon among other things, it appears mame2003-plus doesn't implement the raster effects (this is especially noticeable on Nebulas Ray where the game ends up being heavily glitched), that explains why it's a lot faster.

Also, there is no reason for 2D being faster than 3D, if anything drawing 3D can be way faster than drawing 2D because you have the possibility of offloading it to the GPU.

Hmmm, I know there's no absolutes but it seems like a impossible comparison if going for apples to apples.

If you look at it from a overview trying to calculate the graphics technical level they have some cross over. Generally speaking 2D and 3D are fundamentally different in their approach.

After a certain level 3D is an order of magnitude more complex with rendering, physics, poly counts, texture quality, FOV, field of depth, etc. I don't even know how a person could really compare the two with so many variables.

You would think they are generally more intensive, after a certain level. I know it's not that simple but I grew up with the idea 3D, generally speaking, is more "demanding" than 2D too if you compare 100 "generally" similar 2D to 3D games. :)

@riverstorm initially, 3D might be more demanding than 2D, but from an emulation point of view :

for a given emulator, hardware rendering (drawn by GPU) is faster than software rendering (drawn by CPU), the only exception to that would be if your device is very unbalanced (very good CPU with very bad GPU)
unlike 3D games, the way old 2D games are doing things is totally different from how modern GPU work, so hardware rendering is basically unavailable for those old 2D games. Well, i'm saying that, but i've seen compute shaders being used to get around differences between modern GPU and old 3D games, so i've been wondering if using them would be possible for 2D games too.

Hi, I would like to know if it's doable to add the driver stv.cpp (Manufacturer: Success, Altus, A wave inc. etc.) to lr-fbneo. The reason is that no emulator seems to work fine for Cotton 2. There is still choppy sound even with autoframeskip. I was wondering if lr-fbneo could fix that.

By the way excellent work. I have created personal theme for each of your systems. thanks a lot.

barbudreadmon

@dteam we don't take requests, furthermore we aren't interested in 3D arcade hardware in the first place (stv is sega saturn).

So, Cotton 2 (arcade) is running by Saturn driver. Thanks for the info.

barbudreadmon

@dteam to be more precise, stv is Sega Titan Video, the arcade version of Sega Saturn (exactly the same hardware)

@dteam I think some version of advmame has cotton (2 or boomerang) playable. It's been a while since I've tried it but it might've been near or around fullspeed. It also works on lr-yabasanshiro though it is slow so you need to enable frameskip but even then it can be choppy. yaba has no skipping audio, though.

For lr-yabasanshiro i'm able to run the Saturn version of Cotton 2 but not the arcade version. It sticks on the cd driver menu.
Does a patch or something exist with lr-yabasanshiro for arcade games using stv driver like lr-flycast (Dreamcast) does for Naomi/Atomiswave.

Darksavior

@dteam I believe yabasanshiro only emulates saturn.

Namco NB-1 is now supported :

Nebulas Ray
Point Blank / Gun Bullet
Great Sluggers
Great Sluggers 94
Super World Stadium
Super World Stadium '96
Super World Stadium '97
J-League Soccer V-Shoot
The Outfoxies
Mach Breakers

I really recommend "The Outfoxies", it's a hidden gem.

Huge. Great to move these away from lr-mame2010, be able to .7z them, and get the performance benefits. Fan of a few of these.

Cheers!

Seibu SPI is now supported :

Senkyu / Battle Balls
E Jong High School
Viper Phase 1
Raiden Fighters
Raiden Fighters 2 - Operation Hell Dive
Raiden Fighters Jet
E-Jan Sakurasou

Note : no, we can't remove that 999 countdown, and you'll have to restart the game at the end of it, the good news is that you have to go through it only the first time you launch the game, sometimes there are also clones (single board PCB version) that don't have that countdown

Another big win. Performance is great after countdown hell.

@barbudreadmon for this earlier released set, there are some issues you should be aware of. FWIW, My test device is a Pi4B. Updated lr-fbneo to commit 578e85f. Let me know if you'd like me to file any of these issues in the fbneo git repo:

Bakuretsu Quiz Ma-Q Dai Bouken (bkrtmaq) controls do not appear to work/respond (eg. cannot add credits).
Cosmo Gang: The Puzzle (cgangpzl) SegFaults after rom is validated line 1285: 12660 Segmentation fault
Numan Athletics (numanath) SegFaults after rom is validated line 1285: 26458 Segmentation fault
Nettou! Gekitou! Quiztou!! (quiztou) boot screen displays Key Custom ERROR can't seem to advance

The rest of the games seem to be working as expected. Hope this is useful.

It's great to remove the lr-mame2015 emulator from these games. Thank you!

barbudreadmon

@roslof were those tests done with latest code ? i can't reproduce that issue on cgangpzl and numanath (i don't have a pi4 though, only a pi3 but that shouldn't make any difference). what do you mean exactly by "after rom is validated" ? could you maybe provide full log ?

I confirmed the issue with the 2 others, thanks for the report.
