PSone SCPH-102 (+SCPH-152 LCD screen) with 76B880E5 (REV.B) BIOS does not go to cyan screen #82

Hello (I also go by wishing4thesun at PSX-Place).

The BIOS CRC is 76B880E5 and the System ROM version is 4.5 (25th May 2000), Europe.

I installed using the Unirom CD via the disc swap trick, it verified fine. I've tried three PS1 memory cards, all are original and all verified against the installer correctly, so I doubt that that's the issue (I've heard about the '64K masquerading as 128K' cards being sold on eBay).

I've tried both slots 1 and 2 and I am using an SCPH-110 controller manufactured by Hosiden, so nothing out of the ordinary there either.

Rebooting with the lid open (and the Blu-Tack removed so it doesn't try to read the disc), I go to the memory card info, and I don't get a cyan screen after 30 seconds; instead, just locks up when the memory card icon fades to black. Nothing. Nothing.

I wonder if this indicates some kind of compatibility issue as apparently someone else filed the same thing over at PSX-Place so I have been told.

The serial number(s), if it helps, are S01-8502538-H / B8502538 for the console, and S01-5031737-C / 5031737 for the LCD screen.

Thank you for any assistance/debugging/troubleshooting, since I am not a programmer in any way, and thank you for the project as a whole. (I love the Unirom UI by the way, reminds me of the C64).
