This is the best news I've heard all year!

The NEC CD is a flip top, so you couldn't change discs without removing the Genesis. I'd guess that's just a size comparison thing... showing you could stick a complete CD system into less the half the space the SegaCD takes.

And the image of the Genesis is just showing him probing the expansion port with an oscilloscope. There's nothing else going on there to make guess about why he's doing it.

At most you could guess he's thinking about putting a modern CD into the SegaCD case (possibly under the Genesis instead of beside it), which would then need a patched CD BIOS to control.

Shhh! I was trying to build false hype! ;)

The sega posts were preceded by this one.  If you ask me, he's just showing off his wares.

Another teaser or...? What's going on there with the expansion port? ;)

https://twitter.com/krikzz/status/530534579615305729


I just noticed that the cartridge PCB says "Mega Everdrive" along the left edge, but it doesn't match the picture of the current Mega Everdrive v1:-

...So perhaps the twitter photo shows a Mega Everdrive v2?

I wonder if it will support Mega-CD ISO loading? Or maybe it even emulates the entire Mega-CD so you dont even need the add-on at all!?

I'm excited, but just hope v1 users will still get at least some of the new features.

After seeing the GBA everdrive tweet, I wonder if the cartridge will support SDRAM, and if so, will it support 32MB (256 megabit)? Kingdom Hearts: Chain of Memories is the largest game on the GBA and is the only game that has a ROM size that large, since the game uses compressed FMV.

I noticed this as well and was wondering if anyone else would spot it.

Considering how many chips are on the pcb, I was assuming it was an old pre-v1 board.

You can tell its a later 'v2' design as it uses voltage shift buffers on the address lines instead of resistors, and krikzz only started using those on Everdrive's designed after 2013 (The latest/current Mega Everdrive v1.01 PCB was designed on 19/03/2012 and still used resistors)

The Famicom Everdrive N8 was the first Everdrive to feature them:-
http://krikzz.com/index.php?route=product/product&product_id=59
"Voltage shift buffers on PPU and CPU bus for matching levels between 5v NES bus and 3.3 EverDrive bus. Far better than simple resistor buffers at reducing noise and power consumption."
Every Everdrive designed/released since has used voltage shift buffers (Except the Everdrive 64, which doesn't need them)

Disc-based systems would be cool, but the libraries are much too big for what puts the charm into krikzz's products: everything on one cart.

That's an interesting point! Still, no doubt we'd all love to see Everdrives for disc based consoles, where the Everdrive uses a hard drive to store the roms. But out of interest, what disc based consoles have the smallest rom file sizes? Is there a disc based console who's entire rom library could fit onto say a 64GB USB stick? I wouldn't be too surprised if this were possible for some very early consoles, especially if their commercial game libraries weren't large.

if it were possible to boot disk images in bin cue format with mp3's then a lot of space would be saved. not sure if it is possible and not a problem if it's not possible but the cd audio seems to take up most the space with sega mega cd, pcengine cd,  amiga cd32and other older cd based systems/addons.
 the actual game data for most of these old games is rather small, a lot of the games appear to be regular games with cd quality audio soundtracks.

A full torrent of Sega CD (USA only) is 64.44 GB, but unfortunately that 1) is compressed, and 2) is in actual GB, not the 1000*1024 that are used for measuring SD cards, so it wouldn't fit.  It would fit on a 128G card though.  Wikipedia lists 210 games for all regions, which if you assume 500 MB each uncompressed on the average would be 105 GB and would fit on a 128G card. 

If you count 32X CD separately, of course, it would fit.

The magic of google gives me 125 games (but lots more non-games) for CD-I.  Depending on how close to max CD size they are, it's *possible* they could all fit on a 64G card, but who really knows.

Jaguar CD has 11 games plus 9 prototypes which should fit.  The Nuon had 8 games and 3 samplers, which may or may not fit depending on how big they are (Nuon was a DVD system).  The PC-FX had 62 games.  This should also fit.

A full library is fine, but it might end up having regional dupes and some total cack
