First time trying to burn roms. Using a GQ-4x4 and trying to burn some super punchout roms. Using roms from SPO mame and all chips where erased and verified erased.
All the FD27128 chips failed at 0.72%
I burned 2 successful M5L2764K, but both failed verify. 1 failed writing immediately.
1 MBM2764-30 failed and 3 said too much data for device.
Anyone know what went wrong? All were punchout roms that were erased so.i didnt think there would be any issue. Watched all the videos on youtube, and searched google and couldnt find any help.
