====== Pi-Storm ======

In the Beginning after digging out my old A500 i wanted 2 keep it as original as possible. 

Very soon i understood that this is not very smart at all and there are much limitation on the one hand, and the costs on the other. 

So for Example multiple ROMs plus Switches are quite expensive AND bulky, some extensions would need soldering, others are not available anymore. 

But then i stumbled upon Pi-Storm and as i'm a Raspberry+Linux-Nerd anyway i choosed this for pimping up my Amiga - leaving "almost orgininal" far behind finally. 

===== Plan A =====

So the new Plan is now to purchase a Pi-Storm replacing Amiga-CPU and use a Pi Zero (not a Pi 3) as Replacement. 

At the Moment i'd prefer the more "Raw" Version without Overhead of a complete Raspberrian-OS - so emu68, but we will see. 

<del>Right now it's still a future Project.</del>

===== Basics =====

Presentation/Information (GERMAN):

"Präsentation von Michal Schulz zum PiStorm / Emu68 auf dem 25. Amiga-Meeting Nord in Neumünster"

Very interesting Vid from Developer of emu68 - also references why the Pi5 is not capable of being a CPU-Replacement because of Architecture and slow GPIO.

===== Partitioning =====

I parted with Linux on Raspberry PI with **fdisk** and MBR not GPT

So i neither used CMD/Powershell in Windows nor [[https://mja65.github.io/Emu68-Imager/|Emu68-Imager]]

Set Partition Types "d" for FAT16 Bootup-Device (emu68, PartNo 1) and Type "76" for Amiga-Emulated-HDs (PartNo 2+3)

I used a USB-Adapter for SD-Card and my SD-Card was recognized as /dev/sda, use fdisk -l to list devices and choose the correct one, /dev/mmcblk0 is the SD-Card IN the Raspberry Pi itself

Create fat-Filesystem with **mkfs.vfat /dev/sda1**

I only created 3 Partitions as i don't know right now if 4th Partition with about 60gb would be usable as one whole Primary Partition or if i would need a extended Partition. To stay as compatible as possible i just used 1gb for Partition 2 and 2gb for Partition 3. Those would be visible on Amiga as whole Harddisks u would have to partition with HDToolBox within Workbench/AmigaOS. 

I'm planning 2 create 4 Amiga-(Sub-)Partitions for the 1gb-Partition for different (bootable) OperatingSystems/Workbench/Amiga-OS-Installations with 256MB each. I would switch/set BootPriority of Amiga-Partitions from within Workbench/AmigaOS

===== Copy emu68 + Configure =====

  * Download ZIP Archive from https://github.com/michalsc/Emu68/releases or (Cross-)Compile yourself

  * Extract ZIP-Contents 2 First Partition

  * Copy ROM-File to SD-Card

  * Edit config.txt if necessary

I changed the Rom-File-Name on bottom of config-file 2 a more comprehensive Name with included version so kick-3.1.rom
