as i mentioned in another thread i recently got hold of the carts/controllers/etc from the EZi, in the hope that they'd all work with my Wiii3 .. which they didn't, of course. well i suppose the various crap sports attachments will fit the Wiii3 controller, but thats it.
but out of curiosity i opened all the carts and i found something quite interesting (well possibly). The Wiii3's 7 in 1 (16bit Nice Code) cart and the EZi's 69 in 1 (VT03 Nice Code) just contain a standard rom chip, as you might expect. the 69 in 1 even works in my Power Joy Supermax, since its a OneBus system, but half the games don't run or have glitched graphics because the PJ is only VT02. I'd imagine it'd run perfectly on something like a Generation NEX or that Subor console the Japanese guy reviewed though.
BUT the Wiii3's 198 in 1 (16bit Niutai) & EZi's 18 in 1 (16 bit Niutai) PCBs have an extra glop-top and all kinds of other shit on them - a bunch of resistors and capacitors and a timing crystal and whatnot. Now I confess to not knowing much about electronics but I've never seen stuff like that on a cartridge before. which makes me wonder if these carts actually contain an additional system on a chip, OneStation-style, that overrides the console's "native" architecture (VT03 for the EZi, and some Sunplus 16-bit for the Wiii3), rather than the console itself being some kind of dual-system hybrid. thatd certainly explain why no Famicom or OneBus cart works on the Wiii3, and probably why the EZi 18 in 1 doesnt work either - the method QSL use to override a VT03 system might be entirely different the one they use for a Sunplus system.
[as for the Wiii3 it seems like its natively a Sunplus SPG288 or 243 or something, but the 198 in 1 cartridge is SPG289. but thats just going from from Nice Code's site and the Chinese copyright database respectively. official info on the various Sunplus systems - and there are a lot of them - is extremely sparse online, Sunplus doesnt publish any public documentation like VRT as far as I can tell. I can't even find a list anywhere.]
edit: mixed up the two wiii3 carts. ahem. fixed that.
