Redump cue + bin set will not load on 3DS

[pa-august]

Content fails to load when attempting to load PCE CDs in the redump format of CUEs with multiple BINs, on 3DS only.
These same sets load fine using PCE FAST on Windows 10, Wii U and OpenDingux Beta.
I converted a copy of Ys to CHD format, and it loaded fine on 3DS, meaning this is not a bios issue.
I think it may have to do with long file names, but I'm not sure. Here's a log:

Ok great.

Is this the fault of the dumps or the core? If it's the fault of the dumps, why does PCE FAST handle them fine on multiple other platforms?

check this as well. i could be wrong, there is probably no fallback bios file to use if this one does not exist (i dont maintain this core, so not sure). in anycase you should be using sycard3.pce for most PCECD games and not the others. Just delete your pce config file when you have the correct bios installed and try again, or just load a PCE-Hucard game and set the core option for bios back to use "syscard3.pce"(assuming you have the file already). close core and load a pcecd game.

I was trying syscard2 at this point because I had some doubts about the integrity of my syscard3 file, then switched back with no discernable difference.

At any rate, the games run fine once converted to chd, so I don't think it could be a bios issue, unless chd files effect the way the bios is loaded somehow.

[negativeExponent]

change back to the correct bios, change logging level to DEBUG for both frontend and core and reupload log again (what i with the <> when editing so it retains the log formatting)

just to be sure, you are not loading .cue/bin in compressed format, right...?

[pa-august]

From the same set I tested Bonk III, and it loaded fine without any conversion to CHD. Below is a log of Bonk III loading, then Dragon Slayer failing to load, plus their .cue files.

Keep in mind that this copy of Dragon Slayer loads fine for me using PCE FAST on Windows 10, so this seems to be exclusively a 3DS issue.

from your logs, this seems to fail on MDFNI_LoadGame or either when allocating memory for surf. If it worked when using chd format instead (which you should), then its indeed 3DS' memory limitation.

Interesting. If this is unfixable, let me know if I should close it. I'm available for further testing of this issue with this set if anyone is interested. Also for the record, this is a N3DS.
