    How are you lovely people? I know cafe-alpha don't sell the USB dev cart's anymore (or do you?). I was wondering if you guys / gals...

    You still need to specify the board parameters, but the Seeed Fusion defaults are fine. You can check the parameters from there if you...

  4. antime replied to the thread Using CPU-DMAC to transfer via USB cart to PC-side.

    If you write 64 bytes to the FIFO every time TXE goes low, then it will overflow and data will be lost. I implemented an output console...

    Very interesting. So the consensus is that there could be a loss of data, or is this the reason why there's a hang, and the host is...

    One thing to note about the FT245R is that even though it uses 64 byte USB packets in both directions, two bytes of each IN (device to...

  7. mrkotfw replied to the thread Using CPU-DMAC to transfer via USB cart to PC-side.

    Thanks for the information. I'll continue testing, and testing the other bits. So far, I've upped the transfer from 64KiB to 860KiB,...

    The register controls some access timings. My understanding is as follows: - If the "previous read" bit is set, then after a read...

  9. mrkotfw replied to the thread Using CPU-DMAC to transfer via USB cart to PC-side.

    Setting SCU(ASR0) to (9<<20) (9-cycle wait) seems to work. Anything lower than that prevents the Saturn from sending the full 64KiB.

  10. mrkotfw replied to the thread Using CPU-DMAC to transfer via USB cart to PC-side.

    Setting SCU(ASR0) to 0x00000000 was the culprit. Can anyone explain, or point to material that explains the concepts behind what the...

    Using CPU-DMAC to transfer via USB cart to PC-side

    I'm using CPU-DMAC, with 1-byte stride, fixed destination, and cycle-steal mode (burst is not supported?). I'm seeing terrible...

  12. David Gámiz Jiménez liked TrekkiesUnite118's post in the thread Translating Grandia.

    So I'm still working on trying to figure out the Palette bug in some of the areas. It seems to be related to file size expansion, but...
