[Suggestion] Lexibook Zeus #4570

Closed dkl3 closed 5 years ago

dkl3 commented 5 years ago

Hi, I don't know where else to post this, so I decided on here.

There's a device being sold on Amazon known as the Lexibook Zeus. It appears to be, of all things, a GBA-on-a-Chip. It's usually NES or VTxx on a chip but looks like this one is an actual GBA on a chip--the games on there are the same as some Jungletac GBA games that happened to be dumped.

Not all of them were dumped, for instance, Deep Storm. There's a start button that functions the same on the menu and the games--it just dims the display. I wonder if anyone (presumably Haze) might be interested?

I wont link to Jungletac GBA games

If somebody does a complete dump of the system I'm sure it could be looked at.

Could also just be running a GBA emulator of course.

dkl3 commented 5 years ago

It would definitely be interesting to find out

ghost commented 5 years ago

We've picked one up for a bit of probing.

dkl3 commented 5 years ago

awesome

dkl3 commented 5 years ago

there's another undumped handheld called 220 in 1 dreamgear gamer go portable. has miwi games and appears to run on sunplus technology. david

it is a pretty common device though--they sell them many places

The Zeus was just a SunPlus thing https://www.youtube.com/watch?v=rPR0aWTJZcU

weird, then i wonder where the jungle tac gba games come in?

dkl3 commented 5 years ago

also for the pausing, it's probably hardware-handled. It only dims the display when you attempt to pause--that's all it does. i have a lexibook zeus of my own, so

ghost commented 5 years ago

pausing with the screen dim is a software feature, there's a button that does it.

the random pausing and corruption in the game is something else. we're pretty sure the ROM is correct now, so that's a bit of a mystery, maybe some extra security. the same game works fine in 'zone60'

dkl3 commented 5 years ago

why would a simple sunplus game have security attached to it?

ghost commented 5 years ago

well it already had the rom under a block of epoxy, and, unlike many other SunPlus games, was encrypted, so another layer of security wouldn't be out of the question.

This has been dumped and added to MAME, so I'm closing the issue. The issue tracker is not a place for general discussion - consider moving the chat to a community forum.
