Wow I havn't been here for a long time this is great news to come back to. I bought a Yeno (Super? will check next time im home) Cassette vision and some microvision cartridges awhile back in view of working myself up to dumping them but I havn't had time with Uni. If they need dumping still I'll happily make them available, I doubt i'd be able to handle the microvision cartridges anyway what little I read on them said they each contain a processor with no shielding and touching the contacts is enough to fry the thing
Yeah, definitely check on the Cassette Vision when you get the chance. The first version is completely undumped as far as I can tell. Some dumping has been done for the Super Cassette Vision, but I'm not yet sure how complete it is.
As for Microvision dumping, hopefully Lord Nightmare will have good news to report soon, as I take it he's working on the Speak & Spell, which uses a similar microprocessor.
