minimig-mist-v1.0 (2015-06-22)

This is minimig AGA for the MiST board release 1.0.


In this zip file, there are several files:
- minimig-mist-1_0.rbf         - the minimig core, place it on the root of your SD card
- minimig-mist-1_0-newcpu.rbf  - minimig core with the (very!) fast CPU changes by Alastair Robinson
- firmware.upg                 - firmware update, place it on the root of your SD card
- firmware.bin                 - binary version of the firmware, used to update the ARM microcontroller through USB
- hrtmon.rom                   - HRTmon monitor code, place it on the root of your SD card if you intend to use it
- minimig.art                  - minimig core boot animation
- minimig.bal                  - minimig core boot animation
- minimig.cop                  - minimig core boot animation
- amigasw/SetNMI               - Amiga program to update the NMI vector location for HRTmon, install it on your amiga harddrive


Usage notes
Two core versions are available - one with the old CPU type, and one with the Alastair's new fast CPU version.
Beside the CPU, there shouldn't be any differences between them, so you can use the one that works best for you.

firmware.upg is also attached, but only upgrade your firmware if it is older than 16th of June 2015.
If it is newer, there is no need to upgrade it.

There is a new option available in the OSD called Turbo, which allows you to enable faster accesses to chipRAM and kickstart.
Currently, the turbo kickstart option is experimental, as some software and games have problems running with it enabled.
You can leave it enabled if it works for you, otherwise disable it.

The HRTmon monitor is accessed with the F11 key. There are currently some problems with the HRTmon implementation - 
it is only recommended to use it without moving the VBR (chipRAM only).
