Lightbulb RomCache040+ released!

RomCache040+ 1.3 ©SpeedGeek 2017 (MMU Handler ©Michael Sinz 2001)

INTRODUCTION:
RomCache040+ is a tool to enable the Extended ROM cache for
68040 and 68060 users. "Extended" ROM areas are used to
make 1MB or larger Kickstart ROMs. These areas default to
"NoCache" in the MMU tables of most 68040/060 libraries.

FEATURES:
- Enables "Extended" ROM cache for the following areas:
1) $A80000 1MB (with ConfigRomA8)
2) $E00000 512KB
3) $1000000 4MB (with ConfigRom100)
- Smaller and faster than the Enforcer MMU tool
- Safer than the Enforcer MMU tool because:
1) It has working 68040/060 library detection code (hint)
2) It has ROM Header detection code
3) It only modifies the CM descriptor bits of the MMU table
- 100% Assembler code
* MMU table setup may determine address range and size

REQUIREMENTS:
- Amiga with 68040 or 68060 CPU and MMU
- 68040.library or 68060.library
- 1MB or larger Kickstart ROM(s) installed

UPDATE:
Use ConfigRomA8 to make a 1MB address space or ConfigRom100 to
make a 4MB address space. The executable file name now excludes
the "+" character to avoid problems with the Amiga Shell.

WARNINGS:
Do NOT use RomCache040+ if the 68040 or 68060 library developer
has already provided you with the tools to do the job (e.g.
THOR's MMU.library). The MMU Handler developer says this code is
a "Hack". This tool uses an optimised variant of this hack and
makes certain assumptions about the MMU table setup which could
cause it to fail (e.g. speed has it's price).

CREDITS:
Thanks to Michael Sinz for his freely distributable MMU handler.

HISTORY:
v1.1 - First release
v1.2 - Removed 4MB Romy support. Added ConfigRomA8.
v1.3 - Added 4MB Romy support. Added ConfigRom100.
