Mini vMac DS R3 - Mac Emu for Nintendo DS

[TheLazy1]

It can run any OS that a Macintosh Plus can, so up to and including 7.5.5.

Oh wow! Really?! I thought that it only ran system 6. XD Okay, great. Thanks a bunch.


Oh, I was just thinking that the only thing the emu is missing is the emulation-cut when you fold the DS. And faster mouse cursor speed in Dpad mode. (;

I will warn you now, while System 7.5.5 runs it is unbearably SLOW.
Don't even bother unless you have a ram expansion since the system software uses 1.5MB of memory as it is.

6.0.8 Is the optimal operating system for the Plus and especially the DS port for cpu power and memory reasons.

As for the power-save when closed feature, I must have forgotten it since I always shut down the DS when I'm not using it.

I've tried this awesome emulator on my MMD and GnM cards. With both I corrupt the drive image as soon as I touch anything. Everything works in the PC version of MiniVMac, so if I open the folder containing the program, save it in PC version, then save that to either card, I can run a program once. Opening any folder or program makes it "Damaged" or "not present", saving crashes the system.
I am using 6.0.8 and like I said everything works in Windows version. On the DS, I can run the emulator and look at this wondrous emulator but moving or opening anything damages it.

Is there a disk image size limit?
If Mini Moose doesn't have the same problems with his MMD, what CF card do you have and what size disks are you using?
I know I am installing everything correctly(including DLDI patching of course)
Maybe I will try to keep disk images under 4 mb or less.
Anyway awesome work Lazy1, I'm praying I can get it to work on the GnM, but if not I still thank you.

The problem may lie with your dldi driver being broken.
Check the original post on my blog, it has a link to a dldi tester.

It's important to know if it's the emulator causing this or just your hardware.
On my end I have not had it corrupt anything, then again Supercard CF support has been excellent.

Thanks for the response. I did the dldi test and it passed all the tests. I've had some success with the MMD but the GnM is just failing me here. It could be too slow with read/write to handle the emulator.Chism mentioned this when he released the dldi patch. I'll test my MMD further. It seems to like smaller files. I had initially made a 100MB drive image, it didn't seem to like that, but I'll test it more.
Thanks again.

WOOT! Cant wait to play oregon trail

I got it to work,and am so happy!

For anyone with a Games N Music trying to get this to work, I had to use my 1gig SanDisk microSD to get this to work. I don't know weather it is a disk size issue or just a quality issue.
The stock 128mb, corrupted all disk images as soon as I touched them.

In my experience the Max Media Dock seemed to eventually corrupt also, causing a need to format my card. This could be a similiar quality problem where a better CF card would work fine.

Anyway I am very happy now.What an incredible emulator! Saves work fine, I can't wait to get into the D&D Gold Box games!

Thank you again Lazyone for an exellent piece of coding.

Thanks but keep in mind most of the work was done by Paul C. Pratt who wrote the main sources of Mini vMac.

A side note:
I am planning to do a re-port based on the 3.x sources sometime in the near future.

I have set a few goals that must be reached before anything will be released, a few are:
- Rewrite m68k core in arm assembly
- Rewrite user interface, allowing for key binding, disk loading and configuration at runtime
- Proper time support
- DS Power management

Still, good to hear people are getting some use out of it.

100MB disk images?! You're insane! 0.0'

I'm using a 2.5MB disk image for my main "hard drive".

What I did was; first I installed System 6 and everything on a blank disk image through Mini vMac on my Mac. Then I gave it the appropriate disk name, and dumped everything in it's proper place on my CF card. You don't have to use dummy images or anything complicated like that.

Here's the blank image that I used.
