    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...

  4. 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,...

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

  7. 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...

  9. 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...

  12. mrkotfw replied to the thread Translating Grandia.

    I'm amazed. I never would've thought a game like Grandia would already have a nice font to use.

    It's essential, for my sanity. Thanks!
