I found the .jed file for the U117, (Gal 16v8d Lattice) in mame as they have been released for some time.
I have programmed and checked the chip several times (and with different programmers) but it doesn't work.
At this point I'm wondering if it's a programmer or program problem.
I'd like to know if anyone has successfully used that .jed file and gotten the Gal working.
Has anyone delt with boot file checksum mismatch error? Replaced u61,known good 2.09 boot rom,known good hdd image, Replaced ram both sets ,known hood u53
No luck any ideas?
