Right, as @mitu stated, you can roll your own image. I have been down that road a few months ago:

@gvx64 Thanks for your reply! Do you perhaps have a resource where I could read about the memory allocation of the pi?

I still wonder why running in lower resolutions seems to help then.

Unfortunately, your suggestions do not apply to me.

I run it in stock version. Let me know if there are more diagnostics I could provide you though! I monitored the CPU usage via htop but I do not know how to do the same for the GPU. I have the 8 gigabyte version, that should be plenty right? While monitoring with htop there seemed to be enough headroom.

@jdoc said in How to get 8-Way / 4-Way joystick controls in Defender and Stargate:

Just had to nuke and pave my system, but discovered that mame2003 changed a bit. This cheat still works, but “mame2003-cheats” has changed to “mame2003-cheat_input_ports”.

So changing mame2003-cheat_input_ports = “disabled” to mame2003-cheat_input_ports = “enabled” will make this work again.

Thanks for this. This may be the reason that the MS Pacman speed button stopped working a few years ago, too. I'm gonna give this a try and see if it helps there.

EDIT: Confirmed. This fixed the issue. I posted on this forum about it ages ago and nobody had any idea what was wrong. Thanks!

@mitu said in FYI: Retroachievements will improve more:

I expected 0.0 to make the game viewable area to be hugging the top size. I'm expecting the X/Y positions for the Custom AR to be anchored top left, so 0 vertical bias should fuse the image to the screen top.

That's exactly the issue I reported. Switch to Vulkan and it will appear as you'd expect. The Y position is only wrong when using gl or glcore.

Play with Bias Y and watch the viewable area in the background. You should see that one single frame where it appears where you'd expect before it pops into the incorrect position.

ADDING: I searched online for others having the problem. They are. Most are using GL and are advising others to set Bias Y to 1. This "looks" correct, but is a terrible workaround for a fairly obvious bug, especially for those who mix render modes.

@Lolonois Thank you very much for your feedback. I'll look into your suggestions :).

@old_arcade_dude I would also like this as a feature, the video doesn't need to play more than once and after that it should fade away leaving only the boxart.

@mth75 Hi how you manage to run the games at full screen? Using box86wine from pi-apps also,Everything I run it's on a window
Thanks

@Jiryn either way, you should probably seek help in the topic dedicated to mame current i previously linked.

@sleve_mcdichael
Thank you!
That's what I was wondering, if Subfolders would be recognized.

Wondering if I should do that with like MAME/FBNeo though the select button does help scroll through games fast.

@Jiryn
i am using the awesome lr-FBNEO Emulator, which is installed by default, for NEOGEO and most of the arcade-roms.
As a second option i use lr-MAME (current) for those few roms, that FBNEO does not support and i wish to have.

The DIP-Switches can be accessed by a Key-Combo that you can define in Retroarch/Core-Options.
AFAIR this option is called "diagnostic key" and the default input is "holding START-Button" (during gameplay/rom running).

Retroachievements are the cream on the cake imo!
Similar to Playstation-Trophys or XBOX-Achievements, just better (great widgets, leaderboards for all kind of stuff...)
Concerning Arcade-Achievements: only lr-FBNEO is supported, another point for this masterpiece.
As far as you want to play for achievements: keep your fingers away from the DIP-Switches as only default settings are supported (which is more than fair)
Fo further information just have a look here:

Not much luck with LR-PUAE. I've tried all the settings that I can think of but Gloom Deluxe runs slower than it does on Amiberry. The later 3D games may just be beyond the capabilities of the Zero2 at the moment.
