Open source flash cart, I like it! Didn't open the schematic... Is that just a flash chip, or does it support bank switching?

 

Edit: Ah, see the CPLD there, nice

 

Yes, there are two hardware registers in CPLD.

 

in ROMpicker mode write into $F000 set rom entry bank (2kB density),

write in to $F001 set BS mode 2k/4k/F8/F6/F4, (and still is space for two more ;) )

 

after setting BS mode value, $F00x hotspots becoming inactive

 

Sorry, for rom picker code quality, it is my very first program for vcs :)
