Not entirely sure what you're asking. You just load the disc image like any other. You change it when it asks like you do any other.

Cool, I'm sure it'll make sense when it comes to it then! Thanks very much.

I've always gone to Disk Control in the Quick Menu when a new Disk is required (ie. for Sega CD multi-disk games).

trapexit

You literally just change the disk using whatever your interface is. Just like you would any other disk.

Disk Control is for systems with built in hardware and software for changing disks while the system is running. Opera/FreeDO doesn't emulate that so it can't have it. It doesn't much matter because most games just save and reboot the system anyway. Just like you would with any other game change.

@trapexit Perfect, so long as I can do it on my Pi with lr-opera then that is fine. I just didn't want to get to the end of a disk and not be able to switch. I don't get enough time to play games these days to have that happen!

I don't know how Snow Job works so I can't comment on it. I saw some playthroughs online but couldn't find the disk swap.

you need to enable the shared nvram option to play multi disk games.
It should read the saves game file and continue from disk two when you load the second disk
I wouldn't recommend that option as a global Setting just for multi disk games and a few odds and ends games .

@gorgar19 Cool, so if I set all the ROM/disks in a game to Shared NVRAM then that should all work fine.

Has anyone got any tips for getting the best performance out of Need for Speed on 3DO? It seems to run pretty well on my Pi4 with overclocking (of the Pi hardware rather than the 3DO in emulation), but the sound is very patchy and it feels like it’s running a bit too slowly (even taking into account the slower speed of the game on 3DO).

Incidentally, does 3DO emulation benefit best from GPU or CPU overclocking? What are the bottlenecks for Lr-Opera on a Pi4?

trapexit

Opera is mostly a low level emulator. That includes the graphics. Meaning that it's CPU heavy. Overclocking the GPU would make likely zero difference in performance.

gorgar19

Just don't globally turn on the shared nvram or your going to run out of save game space pretty fast even if you used the game guru to compress the games your not currently playings save game file your going to burn through the 3do's memory fast.games like theme park alone will use most of it.

Unless the developers add in an option to enable the FZ-EM256 256 KB Expandable Memory Unit and I have no idea how that could be done

trapexit

There isn't any real info on the expansion memory unit but I'd like to try to implement it. That said it really wouldn't help that much as you have to explicitly move data to and from it AFAIK. (I have one but haven't played with it yet.)

The NVRAM is actually formatted with the operafs and I've been meaning to test if simply expanding the virtual storage would work. It's on my roadmap.

Has anybody experienced graphical glitches on Myst and Star Control 2?

Every time I get to a place where there should be a fade between two screens (ie. when I get nearer to a planet in Star Control 2), the fade screws up and I get an abrupt cut and a visual glitch.

I'll try and get some pictures up tomorrow.

I have star control 2 run pretty well.
Anyone got to play
'escape from monster man' / 'killing time'
and it dosent leg/glitch ???
its really leg's/glitch om my side...

I'm pretty far into Killing Time now, but it doesn't run amazingly well. It's playable but very very on the edge, I really liked the premise of it and have carried on playing it for a lot longer than I would have in most other situations.

There is some discussion about which settings to use earlier on in this thread, but there was no conclusive answer. Threaded DSP might make some difference, but it also makes the opening video crash (but you can either turn the setting off and then back on to get round that, or just use a save state.

I can get u ...
but a shame that the movies in the game (like the walking people that talk to u really lag's..)

Zering

Escape From Monster Manor runs full speed on my rig, but the sound is so bad it's not worth playing.
Killing Time is choppy from the get-go, and as a matter of fact I'm fairly certain it ran better when my pi was not overclocked. I may have to test it further.
On the other hand, and I was quite surprised, Wolfenstein 3D runs beautifully, and actually I think it may be my favourite game on the system so far ^^

Also, save states don't seem to work on my end. I can save, but whenever I load my states I get a black screen, and I can't do anything except quit the emulator.

As for Star Control and Myst, I want to emphasize that they run full speed on my end, it's just that graphical glitch that winds me up.

Some of those in game videos are much better than others. I find it is in larger rooms within the mansion that the frame rate really takes a turn for the horrendous.

I'd be very interested to know your findings here, I'd love to be able to play it a bit smoother. I think I will end up completing it regardless, but better performance would be nice.

I haven't tried Wolfenstein on 3DO, is it a good version?

Weird, I haven't had that problem on 3DO.

I haven't noticed this, but haven't played them extensively at all.

I'll try Killing Time later tonight and let you know.

Edit : Tried it and it is very choppy, although the framerate gets significantly better inside the labyrinth. At times, the gameplay actually feels the way it should, but the sound is atrocious throughout. So I think we're having pretty much the same experience with this one.

It's glorious, it looks, sounds and handles great.
Having said that I've never played the PC version much, so I'm not sure how it compares, but the 3DO port is certainly worth a spin.

I haven't noticed this, but haven't played them extensively at all.

You really don't need to, the glitch shows up ten seconds into both games. Just try switching screens on Myst or approaching a planet in Star Control.
