64DD emulation about mupen64plus-core HOT 21 OPEN

This issue exists I think it would be practical to use it for discussing 64DD implementation. @bsmiles32

Saving support is for me good enough to be merged:
#829

However there's still a lot to add for more advanced full 64DD support:

• Saving Support (I think it's ready.)
• D64 Edit Bug Fix
  D64 Full Disk Saves is broken because of a miscalculation in LBA RAM End. MAX_LBA should be used instead.
• Disk Access Time setting
  Settings for both instant and delayed mechanical response. (Paint Studio prototype needs the latter.)
• Disk Swap
  One of the 64DD's main feature is to swap disks to access other game contents.
• Game Info to Plugin
  The ability to send Game Info to the plugin. Project64 currently forges them using the regular N64 ROM header format.
• Disk only Loading
  Ability to run a disk game like a ROM. Currently a ROM that isn't combo (not C***) is required to launch 64DD games, which is a bit unconventional.
• Support for RDB
  And of course the emulator has to be able to configure itself depending on the 64DD title.

LuigiBlood has put a lot of work into reverse engineering the 64DD and provided implementations for other emulators. Does it make sense for 64DD support to slip through the cracks in M64P?

from mupen64plus-core.

64DD support in m64p make sense, I suppose we simply lack of developers tackling this problem. :(

from mupen64plus-core.

I still want to tackle this but I need help on this one.

from mupen64plus-core.

@LuigiBlood So have you made any progress on this, LuigiBlood?

I would be willing to help, but I don't think the debugger and other stuff works in the GUI's does it? I use Mupen64Plus-Qt...

from mupen64plus-core.

Absolutely none, and the apparent lack of interest from m64p devs doesn't help at all. D:

from mupen64plus-core.

@LuigiBlood Huh. Not even sure what to say about that. 😞

Is your fork up to date with the latest changes?

from mupen64plus-core.

Honestly you may see 64DD support for mupen64 core for RetroArch (I promised it). And we'll see if I'll port that at some point.

from mupen64plus-core.

@LuigiBlood What about BizHawk? I know that sounds weird, but it is pretty much the same kind of thing, right?

from mupen64plus-core.

BizHawk is more special. But not my priority yet.

from mupen64plus-core.

@LuigiBlood More special? 😆

I understand, I didn't know it was much different from the RetroArch core other than some Banjo-Kazooie/Banjo-Tooie additions.

from mupen64plus-core.

@LuigiBlood How's going with the 64dd support in m64+? I'd love to try some Mario Talent, unfortunately I can't because I'm on Linux and thus Project64 is not on the table.

from mupen64plus-core.

I did implement it in parallel-n64 back then... but I honestly don't remember how I really did it.
Plus implementing it here means I have to manage saving and stuff proper and I don't have that much time for that yet...

EDIT: If anyone wants to port my code feel free to ask me questions and I'll still try to help, no problem.

from mupen64plus-core.

Alright, I'll check parallel-n64 then, it's in RetroArch, right? Thanks.

Obviously I still want to see some 64DD emulation in m64+, but there's no hurry, maybe one day, now that there's some valid alternatives for Linux in the meanwhile...:)

from mupen64plus-core.

That said, even in parallel-n64: Japan Pro Golf Tour 64 is not in a playable state. And it seems to be an issue not related to graphics.

Reminds me that it does not support disk swapping, which 6 games makes use of.

from mupen64plus-core.

@loganmc10 since you're very active in the project now, maybe you have some interest in getting LuigiBlood's 64DD support merged?

from mupen64plus-core.

If I did take on the task I'd probably look at the implementation in PJ64, since I assume it's more complete. I've become pretty familiar with the code and the interrupt system and whatnot so I think I could do it.

Honestly though I find myself lacking the motivation on this one... all the games are Japanese...I might get to it someday just for the sake of completeness, but probably not soon.

from mupen64plus-core.

May wanna look at parallel-n64 code where I managed to make it work.

To be honest it has been a while so I can't tell you how I really did it. But it's basically like my implementation in Project64 with forced interrupts because mupen64plus literally cannot be trusted for that (IIRC)

from mupen64plus-core.

Honestly though I find myself lacking the motivation on this one... all the games are Japanese...

Then there's a good news for you: A translation, made by LuigiBlood, is available for Mario Artist Talent and Mario Artist Paint.

Hi there i had compile to a custom prefix the latest version of mupen64plus and its all components, but i don't had idea how i can start N64DD Emulation

Someone can explaime because i try things like :

./mupen64plus --dd-ipl-rom iplrom.n64 --dd-disk sm64dv.ndd

The thing of Each Config per Title, is a thing some years i got i mention like a Feature Request, because i had a lot of configurations of mupen64plus.cfg for games i had, because the configuration for Perfect Dark, is very different for Mortal Kombat Trilogy, or Mario Party 2.

Specially when i just play with keyboard, and each of them works better with a specific combinations of plugins, and very specific configuration per plugin, hardware depend, to get the equilibrium between quality and performance.

i suggest use the title and/or the CRC of Rom or MD5 of each know rom for auto-generate the configuration file per title. independent if n64 or n64dd. a feature like that can be very useful on projects like this or pcsxr svn

i forget mention, some weeks after of that i can play n64dd emulation here a video
