Hi.
I have to repair a C=64 cartridge (Cpitan Niki II) and the damaged eprom is 27c256.
I'm not sure what file I have to transfer, but almost certainly is this:
https://www.dropbox.com/s/x5z09qw4j1fs00f/Captain_Miky_II_NIKI2_Rename.bin
and it is a 32k binary (I think was dumped from a 27c256 epr).
My eprom is a sst27sf512 re-writtable, and it is a 64k epr.
How should I set this eprom with GQ-4x programmer? (possibly without soldering jumping from one pin to another!)
Software is GQ-4XUSBPrg.
Thanks.

27C256 is a rewritable chip. It is EPROM. You need a UV eraser to erase it before write new data. |

Many thanks. So at least I know that sst27sf512 is not compatible for my purpose. I need a 27c256 epr. But is there 27C256 epr "rewritable" for Willem GQ-4X programmer? |

There should be no any setting needed.
It should be a drop-in replacement.
You just need to select sst27sf512 from software and write the data file. You need to erase the 27SF512 and do blank chck before write it. |
