Other Anyone ever seen this?

[Zetrox2k]

hey guys, wondering if anyone has seen this before. its a multicart and jamma adapter for the Super Famicom that I have been able to find exactly ZERO information for. Far too sophisticated to be a one off/homebrew project...

hoping someone is able to shed more light on this, or even better, eeprom dumps as a couple seem to be questionably faulty.

Did some internet digging

Found someone selling one on ebay
This might have some more info about it as well

Nintendo Super System controller interface and snes to Jamma adapter

It has been my experience having owned several of these machines that the arcade computer fails and is unfixable. So what do you do with the cabinets when the computer dies? Most people part them out

interesting read but both of these seem to be drastically different from the one im referring to.

board says "world technos", maybe belonged to technos and they used it while testing/porting arcade to sfc ?

cover those EPROMs so they don’t self erase

I've never seen that specific board, but ones like it were fairly common in south America and Asia - not so much in the US or Europe because home console games are typically licensed for home use only and trying to use them in arcades in more litigious countries would get you sued.

The presence of lots of Goldstar 74 series chips makes me suspect it was made in some place like Korea, Taiwan or Hong Kong - in the early 90's they were by far the cheapest and most readily available MSI/SSI logic you could get in Asia, but were quite uncommon anywhere else.

From the look of it, that Lattice CPLD, the Z80 and the ROM and RAM next to it are running the code to control the board, the other EPROM and the RAM next to it holding a "game" that contains the menu the user uses to select which game to play and the chips below that are buffers and decode logic that drive the cart adapter board.

Pretty sure we are past that point... cant get it to boot, and cant get a clean dump of existing eeprom, hence was hoping someone was able to dump them.

thought about something similar, though historically in their snes catalogue, i cant see anything worthy of an arcade port, and eventually they did go bankrupt. plus, this seems way too elaborate for a developer to have designed and manufactured.

bumpetty bump! still chasing info on this bad boy!

This is a shot in the dark, but is it possible that the multi cart board is for a super nintendo kiosk display to give people timed demos if new games. I saw something like this for another system of the same era but it was complete, not just the pcb board.

Another long shot.

Technos Electronics (Nepal) have a logo of the world in their branding.

However they say they were formed in 2013 but perhaps they existed before, plus they state - unsurprisingly - the products they sell are made in Taiwan and China.
