Nice. Have you fixed the bug in gmod2 that makes the cart not work with all c64 revisions? I think it's a timing issue of sorts (haven't experienced it myself, just read about it). Quite problematic if it's made for commerical stuff. |

only the flashing does not work on all revisions, which is no problem, since the customer is not supposed to do that anyway.
but yes, flashing gmod3 will work on all c64, and it will be available to endusers too. |

Would be very interesting to compare BOMs. |

I see! I kept it simple and just replicated Skoe’s logic into the PLD including the delay of 1 dotclk etc. If I find cheap 2 or 4 MB chips I’ll add option for that. Up to 4MB would still remain EF1 compatible (256 banks). |

WIP specs are here... its a bit "different". probably due to the low cost design jens is aiming for (it uses a SPI flash). |

I did a similar experiment using cheapo SPI also but got tired of not being able to bring the chip into qspi which is needed to meet bus requirements. I have a design based around an stm32 arm controller at 80mhz + a qspi chip which in theory just barely will meet timing requirements. Got totally bored of coding it so I designed this new cart instead. |

The adapter board hosta the qspi-flash and then a Nucleo dev board is attached on top, just for quick experimenting using arm-based bus logic.
