Upgrading a Microbee PC85 to a PC85b and adding extra Game ROMs.

This is not the first time I have seen uBee512 not emulating a hardware deficiency, I have seen several examples over the years.

Same here, my biggest concern is with CF images.  Images that boot in ubee512 and allow you to copy files to and from your PC HD but do not boot in real hardware.  While images that do boot on real hardware while they boot up in ubee512 but you cant copy files to and from them.  So for these I have to use the slow process of using a Gotek to transfer files on real hardware, doable but substantially slower.

My PC85 has Mask ROMs in A, B, C & D and its only Roms C & D that has 5v connected to pin 26.

Both pics in the above post were added in the same way and both should be thumbnails.
