The SDK should be backward compatible. Which version did you have to use?

I used r695 (which I found on some Chinese website). The latest version (r866) seems to produce versions that crash.

I see you made a 7.5.5 disk as well Any software coming along with it?

There isn't much software that would work well with this emulator in its current state. Most applications from the Macintosh Plus era expected a 512x384 display, and couldn't even take advantage of larger displays let alone smaller ones. This version of Mini vMac is compiled to emulate a Macintosh with a 320x240 display, something that never actually existed. Mini vMac does have built-in support for scrolling the screen when run on lower resolution devices, but I'm not sure if this currently works on the Nspire. It is definitely a feature that should be looked into, and may require actual mouse support instead of using Mouse Keys.

EDIT: I'd like to be able to compile some Mini vMac builds for myself, but every version I compile seems to eventually crash. What might I be doing wrong?

That's good to know, I'll see to fix this in a future build. Thanks for testing
If you keep pressing, the mouse should accelerate.

It doesn't accelerate properly. Sometimes it works, but sometimes it doesn't. I can't figure out exactly what triggers it.

EDIT: I found the problem. It turns out that at the default speed of 8x, the keystroke isn't reliably repeated continuously because the Nspire is too slow to keep up. Changing the speed to 1x fixes this, and also seems to speed things up in general. I think it would be nice if this were made the default option (Ctrl S Z switches it to 1x for now).

Ah, I somehow misread that you had a touchpad. I have only tested it on touchpad/cx hardware. Hmm, the problem might indeed be the touchpad driver I'm using. I'll see if I can find (but that will have to be tomorrow) the version that doesn't have touchpad support. If you can't wait you could try to compile the source code yourself, it will be without touchpad support by default (because you need to patch nSDL if you want that).

I tried compiling it myself today, but the file produced doesn't run properly on my Nspire (just hangs with a black screen). I'm sure I'm just doing something wrong, though I'm not sure what.

Have you had any luck finding the version with no touchpad support?

EDIT: I got it to build. In the version I compiled, the mouse cursor appears in the top left corner instead of the top right corner. However, it still hangs shortly after booting.

Hmm, very strange. Are you running any other Ndless program that possibly could cause this misbehavior? Or do you have a very full device? Also, did you put the files in the correct directory (I assume you did, but you never know) ?

I don't think I'm running anything else at the moment, and the device should have plenty of space. I put the three Mini vMac files in /ndless, which I believe is the correct directory.

Hmm, I've successfully used in on a touchpad. What version of Ndless are you using?

I'm using Ndless 3.1 r866.
