Weird Mouse Cursor bug in MAME (non-libretro)

It's not a MAME bug. It doesn't happen in MAME on any other platform.

Again, it is a MAME bug, because retropie isn't applying any change to the MAME code...

@JSM said in Weird Mouse Cursor bug in MAME (non-libretro):

Samples are always inaccurate, to varying degrees. These aren't direct digital copies of the audio from the ROM at it's orignal bitrate and waveform bandwidth. They are analog waveform recordings (magnetic media recorded approximations), converted to low resolution digital audio format. They are subject to the quality of the recording format, equipment, and media and knowledge of audio capture engineering used by the sample recorder.
They are the functional difference between an MP3 converted at 128kb and the original master recordings made in a studio on 2inch analog tape (or 96Khz Digital audio capture in Protools, etc.) They are sampled and then converted to a lower resolution (lossy conversion) format to allow for quick playback due to smaller file size, based on game mechanic triggers in the emulation.
I'm not an emulation coding expert, which is why I come here to report bugs for others to correct in the emulators. That is what this forum is for.
But I am a professional audio engineer. I have a bachelors degree in Audio Engineering from Berklee. I work as a studio engineer and producer in one of the premier recording houses on the east coast. While I appreciate that you feel you have to "defend your turf" because you're on the FBNeo dev team, please don't try to lecture me on audio quality.

And yet, when you compare a Donkey Kong cabinet with both emulators, FBNeo actually sounds way closer to the cabinet.
Note that the dkong samples were carefully re-recorded long ago, if you were to use the original samples that were released back around 1998 (probably the ones you refer to with your "magnetic media") then yes, the quality would be bad.

Just to expand on this and on the fact that's happening only on the 'RetroPie platform' : what's specific to RetroPie is the fact that we're running without a desktop environment (as you mentioned earlier).

This means we're using the RPI SDL's drivers for rendering and event/input handling. There might be issues with that specific RPI driver, which, due to the limited target audience, might not appear on other platforms (PC/X11/Windows/etc.).

However, by running mame in the desktop env - as tested earlier - means that a well known and used Linux rendering path/driver in SDL is used (X11).Since the issue appears also in this configuration, as @JSM reported, then I don't think the RPI driver is at fault here - as far as this rendering path is concerned, the RPI is just a normal Linux desktop environment.

@mitu Yeah, only a MAMEdev could tell what's going on since they have the better knowledge of their codepath.

No, it doesn't. Not even close. I've tested it at Funspot in NH with their real cabinets. Plus I played them all in real time in 1981-83.

FBNeo sounds like the NES version. Not the original Arcade version.

Sound on the real cabinet isn't muffled the way MAME emulates it. You can easily find videos of the real cabinet with good enough audio to confirm this, and anyway bad audio would muffle the audio but not the other way around. I suppose maybe the amp present on those cabinets isn't emulated by MAME or something, iirc they consider it's not part of the machine. FBNeo won't have this issue since the recorded sounds are most likely already amplified.

Meaning in noisy environments and/or very long ago.

Yes, it is. On every real cabinet I've ever played. As recently as a few months ago.

LOL. This is the same argument you pulled last time this discussion came up on reddit and the video link you posted was a compressed, pixelatted mess on youtube.

No, meaning actual, recent, real world experience. Unlike you googling up youtube videos of a cab you've never played in real life.

Ok, so you are saying literally every video of that cabinet you can find on internet are fakes, because there isn't a single video that confirm your version.

Oh, so you are that super toxic guy from reddit a few months ago that was insulting people who were telling you the exact same thing, aka the fact that all videos of the cab confirm FBNeo is closer to the real thing. I remember you were even telling some well-known player (not billy mitchell) was playing on a mame cab and not the real cab to justify yourself when someone (not me) pointed you to some dkong video. So you knew who i was and still decided to insult a project i work on in this topic, while i even spent half an hour searching through my browser history to find that lr-mame hiscore tutorial to help you.

Which isn't worth a shit in noisy environments like those.

Anyone interested can search for videos of the real cab and see who is right, so you aren't worth spending more time arguing.

Yes. I am the same guy. No, I wasn’t , and still aren’t anything approaching “toxic”.

I posted a thread with a bug report about a specific version of MAME, and instead of getting useful answers or an actual case opened to investigate and repair the bug, I got you, FBNeo “dev” and superfan # 1 telling me “just use FBNeo, it’s better!” Even though both times I explicitly asked in my FIRST POST, “please don’t recommend other emulators, I’m asking how we can fix this version.” And regardless of me asking politely for no alternative emu recommendations, you came into both threads and made both of them an argument.

Go away.

I did answer from the beginning :

for MAME standalone, you should ask the MAME team, because retropie is using vanilla MAME without any change, so they are the only people who can help you
for MAME libretro, i told you that it was possible to save hiscores, according to something i read, and linked the tutorial later, right before you started being disrespectful toward my project out of nowhere

No you didn't say anything of the sort in this topic, the first time you talked about other emulators was only to be disrespectful about them. I can't guess you'll be toxic if i suggest trying other emulators, and i was only trying to be helpful since the answers allowing you to keep using current MAME didn't seem to be of any help. If an emulator appears to be broken in an unsolvable way, i suggest trying other emulators, that's the right thing to do.

@JSM said in Weird Mouse Cursor bug in MAME (non-libretro):

just use FBNeo, it’s better!

No, i never told you once to use FBNeo, you were the first person to bring that name, only to make false and disrespectful statements about it. I couldn't care less which emulator people are using, and considering the kind of person you are, i'll be grateful if you don't use my work.

At this point it's pretty clear you are toxic and a compulsive liar.

@mitu i'm past the point where i'll be able to stay polite if that guy dares answering again, so i recommend closing this.

Understood. Can't please all users, as much as you try.
