NMC27C64 roms no longer program or identify properly in v3.93

Was all fine and dandy in v3.71

Wasted 3 roms figuring this out to.

Why do things get broken with new updates???

The exact model number of the rom is NMC27C64N200 and they are confirmed as original old stock not s**t from china!!

Hello mypinballs,

This is a strange situation, we have not made any changes to the related part of the algorithm for this device.

In order to investigate this, please provide us with the complete contents of the LOG window (Help > Create problem report) so that we can see the behaviour of your devices during the attempts to program.

Of course, please start with the Selftest... of the programer using the supplied 40pin diagnostic pod.

The first step I would recommended: Pg4uw v3.71 is available here. Please download and install it, and see if the situation improves. Please let me know either way.

Best regards,
