Hi Megavolt

Great work. would you possibly be able to show your flash routine for supporting the SST39F.. I have repaired a cheat cartridge using an 39SF020 and wanted to try and flash it with xflash/nxflash.

Isn't the pin numbering wrong?
Shouldn't it be that instead?

  36 ... 68
35 ... 67
  2  ... 34
1  ...  33

Would this work on an SST39VF040?
