[Core regression] Cannot load .cue files

[stevenstrike]

Loading any .cue files will boot straight to the 3DO bios and show the "Insert CD" screen. (no errors returned in the log file about this)

Loading .bin is fine though.

(Loading cue files on the non-libretro 4do emulator works) Windows 10 using latest RA 64 build

Edit 2017/05/29 : A workaround has been implemented, see @fcatrin comments.

[ofry]

Now if I rename .bin to .iso, it failed to start too (shows the "Insert CD" screen).

So this core is completely broken now :(

[ofry]

In 4do 1.3.2.3 all working fine... But I can't use xBRZ scaling in this emulator :(

[inactive123]

Works fine here, I'm going to presume you guys are testing this on Windows again? Guess somebody will have to bisect there and provide a fix, works fine here on Linux.

[ofry]

Yes, I use Windows 8 Professional :)

[ofry]

Which compiler I should use for building this core? Can I get build tutorial?

When I convert .cue-.bin pair to *.iso by WinISO http://www.winiso.com/ game was started.

[nitro322]

Confirming this. Have a redump-verified image of Road Rash in bin/cue format. No matter how I try to load it, I simply get the default 3DO bios prompting me to Insert Disc. However, if I use bchunk to convert the BIN file to an ISO, I can load that perfectly.

This is under Linux (Gentoo amd64) w/ RetroArch 1.5.0 and 4DO core 1.3.2.4.

Understand you need to prioritize, but it would be nice to get this resolved. I prefer to keep my images in BIN/CUE format so I can validate against redump.org.

Thanks for your work on this. As far as I'm aware this is the only functional 3DO emulator on Linux, so even as-is it's a real treat. :-)

[fcatrin]

I've just added a pull request to support MODE1/2352 images (with a .CUE file)

https://github.com/libretro/4do-libretro/pull/26

[nitro322]

That's fantastic. Thanks!

I just played around with the latest build (since twinaphex was so quick to merge) and can confirm the following:

1. Loading retroarch by directly specifying the BIN file of a BIN/CUE pair works
2. Loading retroarch by directly specifying the CUE file of a BIN/CUE pair fails

Judging from the comments in your commit, that appears intentional, correct? May I ask why? Most other systems/emulators I've messed with tend to accept CUE files instead of, or sometimes in addition to, the BIN file. In terms of consistency it seems like that'd be desired here as well, but maybe you have a technical reason for not supporting it?

Either way, I appreciate the work you put into this. Thanks a bunch.

[fcatrin]

Yes, it is intentional. It was for simplicity: Some games are distributed as ISO with no CUE file, and some others are distributed as ISO with a CUE file. In the latter case, I don't know if the game may be detected as two games or not, because both files would be accepted as valid media. Also, accepting CUE files would require more parsing just to get the file name of the image file. So I thought that it will be easier to accept image files with an optional CUE file.

[ofry]

But in that way I can't load CUE+BIN game from retroarch interface.

If I select BIN, suggested cores haven't 4DO. If I select CUE, I go into BIOS.

So please do accept CUE, if valid BIN presents in CUE path.

[ofry]

In the latter case, I don't know if the game may be detected as two games or not, because both files would be accepted as valid media.

About this: I don't know is 3do game scan works... (it will libretro-database issue then). But in PSX games (redump format) only CUE's has added to playlist if I scan directory from RA.

[fcatrin]

The problem with 3DO is that not all files have "CUE" files, so if you require a CUE files those games will not be added. If you require BIN and CUE files, may be both will be added (I cannot confirm that).

May be the suggested cores feature is using the info contained in the .INFO file for that core. That should be updated:

Currently the 4do_libretro.info file has: supported_extensions = "iso|cue"

It should be: supported_extensions = "iso|bin|img"

Can you try updating that file?

[ofry]

I don't understand it.

If load CUE file, but BIN file doesn't present... for example, Beetle PSX will simply "fail to load content".

About db scan: I will try this feature.

[ofry]

3do games scan DON'T working, so this is shouldn't be a problem.

RetroArch [INFO] :: Parsing CUE file 'C:\Users\ofry\Downloads\3DO\lucienne's quest (u)\Lucienne's Quest (U).cue'...
RetroArch [INFO] :: Found first data track on file 'C:\Users\ofry\Downloads\3DO\lucienne's quest (u)\Lucienne's Quest (U).BIN+0'
RetroArch [INFO] :: Reading first data track...
RetroArch [INFO] :: Comparing with known magic numbers...
RetroArch [INFO] :: Could not find compatible system.

[fcatrin]

"If load CUE file, but BIN file doesn't present... " That case will never work, because the BIN file is the CD image, the CUE file is just a descriptor for the BIN file. If you have a CUE file without a BIN file, you don't have a CD image to work with.

3DO will not open CUE files. It didn't do it before and with the new patch it won't do it. To understand the issue forget about the CUE file for a minute. The original code assumed that all CD images have 2048 bytes per sector. Everything different didn't work. The new version will first try to find a CUE file for additional information about the number of bytes per sector, the cue file will make it use 2048 or 2352 bytes per sector. If there is no cue file, the new version will try to guess dividing the image file size by 2048 and 2352, it will use the size that fits perfect with that sector size.

As you can see, apart from getting that number, the cue file is useless. Other systems like playstation and dreamcast require to use the cue file to support CD-Audio, that's why they always will have a cue file.

From your last post, I guess that RetroArch is trying to parse a CUE file, but as I said, some games don't have a CUE file so it cannot be mandatory. You have to pass a BIN, ISO or IMG file and the core will make the rest. The .info file should be updated to remove the CUE extension from the list.

[ofry]

Maybe it's useless, I don't argue with it.

But why don't just parse BIN or IMG or ISO file from CUE? Little feature request :)

[ofry]

Standalone 4DO opens CUE file normally...

[fcatrin]

it can be done only that I cannot do it right now. In the meanwhile, all non working games should load fine with this new version.

[stevenstrike]

OK for the workaround, but i'd like to keep this issue open as long as the proper regression isn't fixed.

[fcatrin]

Due to popular request, I've updated the patch to include CUE file support instead of CD Images only. https://github.com/libretro/4do-libretro/pull/28

[ofry]

Yes, it's working. Thanks.

Issue can be closed, I think.

[mccorkled]

I realize this is old, but I am getting this error on Beetle PSX HW when dragging a cue in.

[hizzlekizzle]

This repo is for 4do-libretro issues only. If Beetle-PSX is having issues with cue sheets, you should open an issue over in its repo.

[mccorkled]

I apologize. A Google search led me here. I was unaware that there were different repos for different cores.
