This is a demo for Spectravideo 328.

For the demo compo at Edison 2015, Imodium made a DIY cartridge HW.
You can view the demo in BlueMSX, but you need a version that supports 64Kb cartridges. This one seems to be ok:

PCB and schematics for the cartridge should be available here:

Wow, great choice of platform... Haven't seen anyone coding anything for SVI for ages. And, knowing the limitations of the old machine, the demo looks great!

How about an MSX port? :)

Instant thumb. That said, this HW can do much more. :)

Nice first SVI demo i ever seen :)

Whoaa! Spectravideo. Nice effects. (Youtube mobile vote... I'd like to see this properly)

@Marq: Most of the effects were developed in openMSX, and then tested on real hardware. I actually automatically patch the VDP and AY code for MSX/SVI at runtime. The major problem is that the memory bank switching is totally different on MSX/SVI. Maybe our next demo will run on a real MSX as well...

@Overflow: I can only dream about doing such a masterpiece as your demo IO.

I don't know anything of that platform, but I liked what I saw on the stream

In the other direction, I've been pondering about porting some MSX stuff for the 328, but didn't get around to it yet, as my SVI doesn't have any mass storage option.

Thumbs up if only for choice of platform. Unfortunately projector screen at the party was stuttering so much it was difficult to make out effects.

Here's an alternative video created with blueMSX : https://www.youtube.com/watch?v=J9LWF-LiyKc

Because I prefer the MSX2 colors, I've runned the demo on an 'enhanced' SVI-328 with the V9938 VDP instead of the original TMS VDP !

never heard of that platform thumbs

Nice parts in it! I very faintly remember some school mate having SVI-328 in 80's and playing with it.

Is the 328 that much different from MSX or were you using some 328-specific tricks?

ok effects, a bit boring music

I redesigned the PCB to make it smaller, and ordered a batch of them, and now I have it running on my old 328, very very cool :)

328 is pretty much a 728 MSX.

Late thumb, cool stuff :)
