Multidisc 32X SegaCD games?
-
@mitu thanks I also found another thread discussing the conversion to CHD format. It ended in a problem using the CD+32x versions of a game together. Has this been figured out at all?
-
@chuckyp genplusx will not play 32x games (only picodrive works and picodrive isn't compatible with chd files). So I'm not sure there is a solution for segacd 32x games.
-
@quicksilver I appreciate it.
Mame CHDs are split per disk. So it looks like I need to convert my own Bin, Cue files into a single CHD.
Getting closer. Thanks for the advice.

Did you get anywhere with this? I can't even get multi-disc Sega CD (i.e. not 32X) games to play beyond disc 1, because I can't get picodrive to attach another disc without it restarting.
-
I have not pursued the 32x issue due to the fact that there are only a couple multi-disk games. As far as the disk changing goes, I don't recall having any issues... Make sure you are opening the tray, changing the disk, and then closing the tray. I have those steps mapped to my shoulder buttons on an XBOX 360 pad. By the way, are you using lr-picodrive or standalone?

I can't get disk changes via lr-picodrive to work even with Sega CD (i.e. non-32X) games - when I try to attach the new disk via "append disc image", I select the cue file, confirm the desired emulator is picodrive, and then lr-picodrive restarts with the new disc inserted - it's the restart that's causing the problem. Apparently this has been a problem in Retroarch before, as I was able to find this (which was about the Windows build, but the behavior is the same):
https://github.com/libretro/RetroArch/issues/5254
I was rather hoping there was a workaround or at least confirmation that others aren't having this problem, since I can't find anything in my setup that would cause this.
-
Can you give me a game to try out myself? Hopefully something that won’t take me an eternity to get to disk 2?

I'm not actually even playing through - my test case for the moment is that I boot up Fahrenheit for the 32X (which won't play - the protection requires you to boot from the Sega CD disc, even on the 32X) in lr-picodrive, wait for the prompt, hit Start, then enter the RGUI, open the tray, and attach the Sega CD disc. Instead of allowing me to close the tray and resume the game (which should then cleanly boot the Sega CD disc, then ask for the 32X disc again), lr-picodrive completely restarts/reloads and the process begins all over again (except this time having booted from the Sega CD disc).
From videos I've seen, once the cue file is selected in the browser in the attach phase, it shouldn't ask to specify the emulator (Picodrive, in this case) - I think that's where something's changed, but it makes it impossible to swap discs at all. In fact, it's not even limited to Sega CD - I also tried this with PSX, where I started a game, ejected the disc at the PSX boot logo, attached a completely different disc (where I was prompted for the emulator again), and sure enough, the PSX emulation restarted entirely. It seems this affects any emulator's ability to swap media (probably not even limited to CD media).
I've tried the following:
- Updating all of RetroPie
- Updating Retroarch from source
- Updating lr-picrodrive from source
I guess it's an upstream bug in Retroarch, but I'm surprised nobody else has mentioned this, because it's a bit of a breaking bug for any libretro game that requires more than one piece of media.
-
It was/is indeed upstream:
-
...though I'm truly mystified.
I've now built Retroarch and libretro-picodrive from tip revisions on Github and it's doing exactly the same thing. sigh

@rhester72 You'll have to wait until the RetroPie team updates their RetroArch, which I would think would come about after RetroArch 1.7.2 is stable.

I built directly from the current (i.e. 6 hours old) libretro source using RetroPie's build script (i.e. I removed the git tag for v1.7.1 and had it pull current, applying the two RetroPie-specific patches) - it's still busted. Unless there's something RetroPie-specific to this issue (which I can't imagine being the case), I still think whatever's going on is upstream...but that brings me back to the question of why nobody else is complaining. :)

@rhester72 Well, the most likely people to be playing multi-disc games in RetroArch are the ones playing PSX, and they have the alternative options of a single PBP containing all the discs (and I'll bet that is what most do) or a M3U playlist for single disc PBPs, CHDs, or converted to single bin & cue discs.

Probably - I'm doing m3u with CHDs myself for PSX. The other systems potentially impacted (Atari 800, MSX, VICE beta) are considerably more obscure than Sega CD.

Personally, I'm trying to get Penn and Teller running and some of the games require Disc 2 to be put in after being selected on Disc 1.

What part of 'Penn & Teller's Smoke and Mirrors' requires this to take place?

@ryguy176 Same here. Same problem described by @rhester72
I can't get disk changes via lr-picodrive to work even with Sega CD (i.e. non-32X) games - when I try to attach the new disk via "append disc image", I select the cue file, confirm the desired emulator is picodrive, and then lr-picodrive restarts with the new disc inserted - it's the restart that's causing the problem.
-
Does lr-picodrive support m3u playlists?

@saccublenda Ive found switching between discs was an issue when select-x to retroarch menu When using bin. and .cue roms. Try using just .iso roms for mutli disk games like night trap and ground zero texas. Worked for me
