* EVB to MP: split(cnc-cut) the EVB into 2, and the below part becames a commercial edition

Additional remarks：

mapper 5, 19 and 90 are incomplete versions, not full functional. i spent a lot of effort to optimize code and reduce into 240 LEs.

here is my n64 multicart designed last year, supports up to 2 giga bits(256MB) flash ROM. and it can combine with different CIC type and different save type roms. i also cloned the abnormal japanese sram accessing mode such as Bio-Hazard 2 and Fuurai no Shiren. i cheated the bootloader to switch games with different CIC type without power on-off. I believe this is the only one MULTI-cart of all n64 cart homebrews.

like always, its the lowest cost solution on the earth

Would you be willing to say some more about this?

Is it some variation of CoolGirl multigame cart? https://github.com/ClusterM/coolgirl-famicom-multicart
At least using of 3.3V flash without level shifters is not good point.

similar to coolboy/coolbaby/pocketgames/mindkids/coolgirl/brazepro, i think it sould be more like BlazePro( a company which specializes producing repro carts)

yes, no level shifters maybe causes some bus compatibility issues, at least in theory. i tested for 24 hours of continuous working. other chinese multicarts have the same physical structure.

if using level shifters, the pcb area will expand to 2 times
