@_dx Thanks for your input. That register list is what I've been missing. I've had the programming guide for a while.

If you don't know, I've got a link to datasheets in a Google Drive folder on my original thread on the shmups forum at http://shmups.system11.org/viewtopic.php?f=6&t=52172

I've already got assembly running on the MTV230 via the ISP function which is entered by shorting port 8 on the GBS boards. The ISP is enabled with the original firmware, and is not locked. So I've already dumped the OSD flash and two different versions of the OFW. I've also found it hard to find any info on parallel writers. I've already bricked one board from erasing the flash and not having access to ISP.

I'm currently working on creating a qusi bootloader and getting serial comms working on the UART port.
