You're doing everything right! keep going!

I've made a disk image of the Micro SD card from the Lexibook TV Game Console, another Wii ripoff:

https://www.dropbox.com/s/xn7q9q5fkrbj5rq/lexibook.zip?dl=0

The Micro SD card is formatted as standard FAT32. The system appears to run a rudimentary OS that likes to pretend it's based on Windows. According to the ELF headers of the executable files, the processor is a Sunplus S+core7, the one used in the Mattel HyperScan. AFAIK there are no working emulators for any S+core-based systems, so I can't attempt to load the disk image on anything.

The only other major component on the PCB besides the epoxy blob is an SDRAM chip, so there is no BIOS chip I can dump. The system will play an animation and an audio loop when the card is not inserted, so there must be some sort of BIOS, possibly under the epoxy blob, but I'm not equipped to go looking for it.

is the machine of value to you? Team Europe have had some success in working out how to dump certain 'blob' based things, although it's sometimes a destructive process with certain risks attached (eg. xraying it to see if there are easy to figure out external connections)

without the bios I imagine it won't be possible to get it going.

These things apparently cost only around 30€, I'd be more than willing to donate towards having them dumped and possibly destroyed smile

I think blobs are probably the next frontier of dumping now that decaps are nearly commonplace (or at least in the TMS1000 thread they are).

Beckie: we appreciate the dumps, and I'm a big fan of your retro fonts. I use the Apple II ones to give 4AM's readmes the correct look smile

I'm not attached to this thing at all, so I'd be happy to send it on. I can probably fit the internals (and the two controllers? would they be useful?) in a bubble mailer to cut down on shipping costs.

Thanks for the compliments!

I found some misc. Eproms lying around:

Sanyo MBC-28, a 386SX machine according to this page:

http://www.cc-computerarchiv.de/CC-Archiv/bc-alt/gb-san/gb-san-12_91.html

Adaptec 1542B

These are the original ROMs my 1542B came with before I upgraded it with a newer version found on (IIRC) the Adaptec bulletin board (I'm old, I know). grin


NCR DMV- DEC Rainbow- Siemens PCD- ITT 3030-Oly People- Acorn A5000- Olivetti M20

Is there any experienced dumper at the Chicago area? We might have a chance of dumping the impossible to find 3D Attack for Arcadia 2001, but the owner doesn't want to risk shipping it due to how rare (and valuable) the game is. This is the last undumped game for the system.

What kind of ROM chips are in the game? Socketed? Will they need desoldering? I hope you, and the owner, realize that to dump it, the ROMs would have to be pulled off the board, read in a ROM programmer, and then put back on the board.

Or someone with an Arduino or similar could wire something up to the chip or cartridge pins, like the VT340 dumper did.
