3DO: The Pi4 Emulation Nobody Loves?
-
Can lr-opera play multi-disk games? I can't see a Disk Control option and wondered if there was some other way that works with this.
I've got a few games I'd like to play that are multi-disk, but mainly Snow Job.
-
Most if not all 3DO multi disc games just save to NVRAM, ask to change disks, and reboot. The hardware for changing disks is not emulated so there is not point in having the disk control API setup since it there is nothing to do.

I am still unclear how this works, if you have multiple ROMs for the same game (ROM per disk). How do you load the next disk? Should I have a playlist file or something like that.
Good to know Opera can run multi-disc games anyway, I just don't quite get how it works yet.
-
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).
-
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?
-
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.
-
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
-
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.

@Zering
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... -

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..)
