Amazing job guys. And thanks Jim for writing this down, I love to read such stories (they make me feel better about all my delayed stuff :-). When I googled that it's x86 after watching the live stream, I just thought "OK, what's the issue then". But after reading the "spec", I know the answer.

Two not so serious questions:
- Really only 1AA?
- 'Owner' info structure :Blood - 1 byte (1 - A, 2 - B, 3 - 0, 4 - AB), WTF?

Yes really just 1AA and I only used a single AA for each year working on it ;)

The japanese seem to have a fetish for blood types or something (http://en.wikipedia.org/wiki/Blood_types_in_Japanese_culture)

amazing story! i think i can also speak on behalf of all evoke organizers that we are really touched that you chose evoke (for several years in a row!) to release this amazing thing. this makes demoparty organising really worthwhile!

and also, since quite much dirt was flung at irokos & titan during the past years: this story, i think, really shows how well the concept of titan as a "big" group works out when it comes to projects like this one.

*There was no API, all that existed was a pretty basic techdoc*
with easy search, there was the wonderwitch, containing development cartridge & SDK in C, since 2000. why did you build all from scratch and not just use it ?
Greetings to pass 6 years to build hardware & software for your demo at least. Looks overkill but FUN!

dipswitch, evoke is our beloved, and always will be. many, many deep thanks for your last sentence.

FreeFull: lol :D

irokos: dude, thanks for putting it so perfectly <3

skarab: We didn't use WonderWitch for a few reasons: it doesn't allow to play or create regular Wonderswan ROMs, it has 4Mbit flash memory compared to Wondermagic 32Mbit, at that time there was no Wonderwitch emulator, and even nowadays (to my knowledge) only a b&w WonderWitch emulator exists. Aside from these facts the hardware is nearly impossible to track down and of course is rather expensive :)

FYI here's a nice PDF on WonderWitch: JB Kun's WonderWitch FAQ

thanks for the nice writeup, good that you never gave up. this motivates me to get back to some of my projects lying around, once i am at home again

alk: thanks for clarifying a bit. really strange all sources are rare, because this machine is amazing, one pile/30h for those possibilities is unbelievable! I guess I understand why you did this :)

skarab: :D! and yeah it's a great console

And it didn't cost anywhere near $400 :P

mic: Nice! Perhaps we can we look forward to a 3rd Wonderswan scene production? :)
added on the 2012-08-26 15:44:21 by alk alk
Who knows :P Though I'm currently busy sorting out hardware details on the NeoGeo Pocket Color (my console doesn't necessarily agree with the available emulators on a lot of things).

"my console doesn't necessarily agree with the available emulators on a lot of things" we had that a lot too. Even the most simple things: the current scanline register is off by one (or changes at the wrong time during the scanline?). Also when loading a value into a segment register you better don't use an instruction that makes use of it for the next few cycles on the real hw (that one was really annoying to track down) works fine in the emulators though

Mic: why is there two cartridges in your photo? Also how much *did* you pay for it? (if you don't mind me asking?)

Thanks for sharing this, it must have been horrible at moments :) Also, I would love to see the skipped effects (the heartcube part looks ace) and saxxon music being released elsewhere.

@alk: I bought it from a japanese guy through yahoo auctions. He had some extra stuff that he included with the original kit (a spare cart, the purple book which is a guide to programming for the Wonderwitch/FreyaOS, and a CD with some updated software tools). IIRC the whole lot cost ~$250.
added on the 2012-08-27 11:20:12 by mic mic
yeah, please release the skipped effects and unused music in another prod!

All debug-versions will be released in Titan artpack 3.
