Usually MBC3 chips only allow for 2MB of flash however by adding a special logic chip, we can extend the flash size to 4MB so you can future proof your RTC cart. There is an MBC30 chip which does support 4MB but carts usually go for $12-18 and aren’t very common where as MBC3 carts go for $1-3 and are everywhere. Re-flashable with any flasher like GBxCart RW that supports the MBM29F033C chip via the audio pin method.
As most users build MBC3 carts themselves, we’re providing this option so please ensure you know how to solder and you will need to source all the parts yourself (check the list below) and we will only provide the PCB and special logic chip (unsoldered). Please note that not all MBC3 original carts have an RTC, the most common ones that do are Pokemon Gold/Silver.
Build it yourself parts required:
The power consumption of MBC3 when powered from the battery appears to be around 2.3uA so a CR2032 should last around 7-10 years.
The PCB finish is ENIG, Gold fingers (on the edge connector) with a 45 degree bevel to give the maximum life for insertion/removal of the cartridge.
If you will be installing this flash cart in an original shell, it is very difficult due to the CR2032 battery holder but it is possible.
