FastRom2MB 1.1 for 68020/030 ©SpeedGeek 2018
INTRODUCTION:
FastRom2MB is an MMU tool which provides up to 2MB Kickstart ROM support to the AmigaOS "CPU" command. The CPU command already remaps the Standard 512KB ROM so this tool just remaps the Extended ROMs and MMU write protects the ROM images.
FEATURES:
- Remaps 512KB Extended ROM @ $E00000
- Remaps 1MB Extended ROM @ $A80000
- MMU write protects Standard and Extended ROMs
- Remaps only into available Fast RAM
- Uses ROM header detection code
- 100% assembler code
REQUIREMENTS:
- 68020 or 68030 CPU with MMU
- 1 or 2MB Kickstart ROM installed (for remapping)
- AmigaOS CPU command (with FASTROM enabled)
NOTES:
The are only 3 Amiga models (A600, A1200 and CD32) which support 2MB of
ROM. Please consider the ROM vs. Fast RAM speed before remapping. If you
want to speed up copy operations see the CMQ&B.txt (included).
MMU write protection is over-rated! This tool will NOT prevent your
system from crashing! But it will increase the chances of having a
"Software Failure" which is useful for debugging purposes.
HISTORY:
v1.0 - First release
v1.1 - Merged FastRomWP code with existing 1MB and 2MB code so the 1MB and WP variants are now obsolete.

very cool.
so which is the best a4000 motherboard ram hack to use to avoid interfering with the romy and this hack?

For A4000 owners the remap size limit is 1MB. The A4000 64MB Fast RAM hack should not interfere with either the 1MB or 4MB Romy hacks. ;)

** 3RD NEWS UPDATE **
FastROMbench 1.1 released
- Changed Public memory to MEMF_24BIT memory. This
should handle the problem of early MMU table termination on
systems with 32 Bit extended Fast RAM.
