and I'll believe it when I see it, the last thing we need is another over-hyped under delivering scheme, the previous one burned such an unbelievable number of bridges I'm surprised anybody has any confidence in us at all now (there's a fair bit of stuff you haven't seen emulated due to people still being pissed off over that and we really should be offering a deep apology) I would take anything said on Guru's page with a pinch of salt, we're even having to apologise all over the place for his behavior, it's becoming a full time job.
Decapping is not a magic solution, unles the parts are MASK parts it guarantees nothing, even MASK parts can be tricky if they're modern. For anything else you're basically depending on there being a read mechanism, having the right adapter, and being able to locate and disable whatever read protection is in the chip, by no means an easy task. Not all chips have read mechanisms, and some are truly custom so you won't find an adapter to read them.
So far, even with a guy who was considered one of the most knowledgeable in the field, all we got were simple mask rom cases, and chips where the deprotect bits were well documented, even then we got a lot of bad dumps and things that needed to be hand fixed. The guys actually doing the best decap work (but again only covering MASK rom cases where decapping is a viable solution) have mostly been working on decapping stuff for the MESS side of the project, quietly, without any real hype.

Tokio should be ok, the Jaleco MCUs I've not heard anything suggesting we can deal with.
