PFR_Detect Test

I've been working on the paging test I discussed with Mike G. in the "Bank switching chip replacements..." thread. It's called "PFR_Detect" (PFR meaning Page Frame Register, replacing the term Frame Control Register (FCR) I used in the SMSARCH document).
I've run the test on 3 emulators: Meka 0.54b, BrSMS 1.21, and Massage 0.80. Here are the preliminary results:
Meka 0.54b
------------------
Region 0x0000 - 0x0400: Fixed
Region 0x0400 - 0x3FFF: Pageable
Region 0x4000 - 0x7FFF: Pageable
Region 0x8000 - 0xBFFF: Pageable
Battery Back-up RAM: [Test Skipped]
BrSMS 1.21
--------------------
Region 0x0000 - 0x0400: Pageable
Region 0x0400 - 0x3FFF: Pageable
Region 0x4000 - 0x7FFF: Pageable
Region 0x8000 - 0xBFFF: Pageable
Battery Back-up RAM: [Test Skipped]
Massage 0.80
--------------------
Region 0x0000 - 0x0400: Fixed
Region 0x0400 - 0x3FFF: Fixed
Region 0x4000 - 0x7FFF: Pageable
Region 0x8000 - 0xBFFF: Pageable
Battery Back-up RAM: [Test Skipped]
Can any authors of these emulators confirm this information?
I will try to run the test on other emulators soon. I also need to clean up the source code, and make the test a little more robust. At that point I will release it for testing on Mike G.s 1 Megabit development cart. Hopefully it will help determine the paging capabilities of the 315-5208 paging chip.
