Description

I am experiencing the same bug as this comment in reddit (from 6 years ago...) https://www.reddit.com/r/RetroArch/comments/hj6d1u/flycast_naomi_loading_error_when_using_zipchd_via/

I create a playlist with light gun naomi games. The one from simple zip are booting fine with flycast from the playlist, but the one that require a chd fail to boot. If i boot these zip/chd games with "load content", they work fine.

And yes these files are the latest mame 0.289 and they are well arranged and such.
It seems to be specific to flycast as i have one another playlist for mame light gun games, and the one with chd are working fine.

At least provide some log and retry with nightly build.

Thank you.

Scanner likely pulled in the chd directly. The Naomi database shouldn’t be used for scanning. Find a mame dat/xml file and use that.

I get the data from mame itself and the following only works in zsh.

cd path/to/Naomi-roms
mame -listxml *.zip(:r) > Naomi.xml

Move Naomi.xml into RetroArch’s database folder and point the scanner to it.

Is it such a hard bug to reproduce so you need a log ? I lost enough time to understand it and retroarch is already on my nerve for other anomaly that shouldn't be and ruin the experience. Come here sharing this is a courtesy and right now i'll stick with standalone emulators.
[dvessel] I have no idea what you are talking about. I don't use any scanning or database, the playlist was create manually. By the way the bug is also present if i add one of those problematic naomi zip/chd rom to "favorite".

If you need help, you need to put in enough work so others know what’s happening. Getting an answer is the courtesy of others. No one gets paid to do this. The least you could have done is to post a log or even the playlist since you created it manually.

Standalone emulators are inherently more simple so if that works for you, then that’s great. Whatever works for you.

I'm a little grumpy on RetroArch i admit. I mostly use it on linux for basic use and it's stable and fast. My light gun doesn't work on linux so i have to setup on windows and it's the exact opposite, it's very slow to start and crash randomly.
The point of retroarch is to have one frontend for all emulators, meaning you set something in retroarch's options, like my light gun, and when you download and use a core it's suppose to be plug and play. Which is not, for mame i had to manually edit mame.ini. For flycast, except this annoying bug i report here, retroarch doesn't keep the controller option when flycast shut down. Meaning i have to set the control to light gun every time i power up the core. And maybe one day i'll solve the mystery of retroarch keep telling me my light and controller are not set up, even if i did set them up.
So yes right now standalone emulator work best for me.
