I can confirm that at least with the VUE Debugger you can get red/green anaglyph from the PAL AV OUT, no need to use RGB OUT for that. You change between the modes using command lines in the pc software. I don't know about the video boy, but it seems likely they used the same components since it's in the same series... Maybe it has internal dip switches for that, if there is no pc connection?

It's actually not a stupid question, so I'll try to explain it.
So, to actually answer the "why" (understanding the system is never irrelevant):

When you power the VB off, some amount of voltage stays in the system capacitors for a couple of seconds. Sometimes it's enough to keep your old data in the VIP/RAM. If you turn it back on again too quickly, before it has time to "die" and go completely powerless, you will see the data still being there.

The VB doesn't have built-in routines to guarantee that all memory will be 0 at startup (even though it most often is) so you should never assume that it is. You should consider the memory to be undefined, and the only way to guarantee a desired behaviour of memory that you use, is to clear it in your own code at startup.

Hey!
I had a nice surprise waiting in the mailbox when I got home today (no spoilers for those who didn't get it yet). A HUGE THANK YOU to everyone involved in its production, really cool work guys!

Hm, I don't know... I just converted the isx with lameboy's tool. Do the earlier released versions of this demo work on hardware?

I didn't remember about those, thanks

vbcvtisx doesn't work for me (not even on the 1.2 version isx?) and ISX2ROM can't handle it either. It appears it isn't an isx file after all, but in vuexe format. I guess it has to be re-compiled by vucc to get an isx file. I haven't set up my vucc environment yet.

However, I did use ISX2ROM to convert the regular 1.3 sample soft to a vb rom, and here it is. The pause screen has new graphics, and the entire rom seems to run faster than 1.2.

Is the 1.3 version of the sample software any different? Did you have a chance to look at the disks yet for any custom code? :-)


Yes! They corrected some flip bug in a graphics converting tool appearently, and added a simple parallax effect to the automatic pause screen.

But! ...Drumroll... What's really interesting about the 1.3 version disk is that it contains a Hudson folder with what seems to be a Hudson version of the same "running monkey" demo. The demo itself seems to look and play the same though

I didn't compare the source code yet, but the isx file is much bigger, so something must be different. I tried to make it into a .vb rom through the debugger, but it just turned into 48 kb of crap

You're understanding the mechanics correctly. The column table is not for compensating for the speed of light :)

However, the mirrors don't move at a constant speed. Think of it as how the Y coordinate moves on a sine wave. At the extreme angles the mirror is moving slower, and as it sweeps over the middle it moves faster. So without compensation for that, the columns at the edges of the image would be thinner and closer together. The leds need to stay lit longer for those columns, or you'd get a squished image at the left/right edges.

Hope I didn't make it more confusing :)

Thanks guys, I would actually love to see it completed myself
Maybe taking up its development again should be my project for "Virtualfest"

This sounds awesome! And impressive that it's so memory efficient! Is it equally cpu efficient? Say you have a game that is already struggling to perform at a decent framerate, how much will playing a song of average complexity bog it down?

Hi cr1901, welcome to the forums
Do you own that debugger? It looks like one of KR155E's pics from this site, but from a different angle?
