Algorithm is the same in the software version I use.in my case it's not 27C128 and 27C256 but 27128 and 27256

CMOS or not makes no difference on my side, they can all be burnt without any issue and regardless of the programming voltage needed (didn't experience more issues with 21V devices compared to 12.5V ones).I'm talking about the chips not the presets
EDIT: Not working on my side
Works for me, thanks Apocalypse@Trol thanks for the pictures, looks identical to the one I've got.

Can you guys please do a test for me? Go in "Cofig" tab and change parameter "delay" to 1ms and try burning a 27C128/27C256/27C512 again.
Dumped all the ROMs, they all read fine except for 01, which I reburnt with no real change (except the faint text down the bottom of the screen doesn't seem to appear anymore).Program ROMs are the ones next to the cpu on the top board. Maybe check them with mame and basic cpu checks then if it just crashing.
