So the roms I sent you haves the same bankswitch scheme as that weird cart? Then The other ones I sent you might work too.. All of them works in the same board I tested here, so I think if one of them works all other must work too. Quote Share this post Link to post Share on other sites

The friend alex_79 member here in the forum, traced the schematics. I converted this circuit to use a 27C512 adding two more switches and now it is able to run eight 8K games. But the bankswitching is the same.. It was not changed.. Quote Share this post Link to post Share on other sites

Sorry for the delay. Covid-19 time it is been a hard days and hard night here. I dumped my two carts today an sent zip files here. Please note that this is a weird strange cart. It uses a kind of special 16K chip that fits a 32K data content. So I did two types of reading. Firstly I did a read as a 27128 chip and after I did a read as 27256 chip. Please Keep in mind that the actual chip is a NMC27CP128Q. I sent attached all the data I got. I placed some pics from the board too. Hope be useful for you. Once more sorry for the delay on dumping the files... READ AS 27C128.zipx READ AS 27C256.zipx Quote Share this post Link to post Share on other sites
