Core won't load anything

[Starman99x]

The first time I tried this core everything worked well, but I'm not sure if I messed something up (from within) because the second time I tried loading the same game all I get is this screen:

How can I reset everything up?

You're getting further than me. That means the minivmac core is successfully loading MacII.rom and is ready to accept a disk image. From the docs, it appears that the Y button should load up a file browser to select a disk image.

I've tried sticking MacII.rom in my system dir and in system/minivmac/ and I still only get a black screen -- the ROM never loads.

Note that, just like in a desktop version of Mini vMac, you'll need to insert a BOOTABLE disk to get past the flashing ?. The bootable disk could boot to the Finder (assuming it's got System 1.x to System 7.5.3 installed), or it could be a custom disk like Dark Castle that carries its own System, but boots to the game instead of the Finder.

Try testing in Mini vMac first, and then use the .dsk files you got working in Mini vMac with the minivmac core. With desktop Mini vMac, you can just drag a disk image over the window to load it.

So... having said all that, what did you do to get to the flashing ? I'm attempting to get this working on iOS and on Linux and getting a black screen in both places.

[edit] tried from the command line to see if any useful errors were spit out. No complaints when loading the core, then when the screen loads black, I get an infinite loop of:

[WARN] [GLX]: glXSwapInterval(1) failed.

Killing the process emits the following useful info:

Open failed
I could not open the disk image.

Does it require a bootable disk image to load the core?

[edit2]
Looks like it does. Once I've added a bootable disk, I get further, and got the message:

Unable to locate ROM image
I can not find the ROM image file "MacII.ROM". For more information, see: "(unknown)".

So, on a hunch, I renamed my ROM from MacII.rom to MacII.ROM. And it worked. Sort of. I got the happy mac, and then I got a black window with some color smears on it.

I've tried sticking MacII.rom in my system dir and in system/minivmac/ and I still only get a black screen -- the ROM never loads.

The file must be in system, not in system/minivmac and the rom must be called exactly MacII.ROM. Once i did like this, I ended up with the same problem, like the system booting but asking for something like OP. Launching a system disk worked and i got a desktop but that's not the point i'm asking to retroarch...
