sram noob?

[sigflup]

In regards to sram, I don't understand. Where's the write strobe on the cartridge pinout? I am not seeing it

There isn't any, you got to do manual address decode. Normally top 2MBytes are used as SRAM range while bottom 2 are ROM range. Games larger than 2MB have a banker that allows top 2MB to be ROM or SRAM depending on last value written to !TIME range.

EDIT: Write strobes are !LWR and !UWR, pins B28 and B29 and !TIME is B31
