Hi, Thanks for the advice! I'm going to try all of that out in a bit (been watching the quake news from Japan all morning, horrible!). It wouldn't surprise me a bit to find something has shifted out of joint...the way the thing is behaving, it makes me think something is indeed 'loose'.

I have not tried any other dedicated homebrew cartridges, I wasn't clear in my post.. my apologies. What I've tried is the original GCE carts I have (about 10), and then the vecmulti. The VM runs many games just fine, including some of the homebrew stuff (birds of prey for example). It appears my vectrex has the most trouble with the larger homebrew games (and I mean larger by the image-size of the binary file).

However, I am able to run some of the larger games, like protector/yasi... though I have that one loaded up on a micro-SD card all by itself that I swap in just for testing. Both of its games play fine when it loads up. Sometimes, it takes a few start/stop cycles to get it to load.

The more I think about it, the more it sounds like something is out of joint. I'm going to go poke around in there and see what I can figure out.

Thanks again!, I'll update this later when I get somewhere!

I'll see about getting video of the errors and things, maybe that will do a better job of explaining than I am able to do.
