The Games We Never Talk About: BOBO STIR CRAZY
Thanks for the memory
When Hyperion Entertainment announced in a 2014 blog article that AmigaOS4 was going to get support for accessing memory beyond the 2 GB limit, the reactions were mixed. Predictably, the most abrasive comments came from people who had never owned an OS4 system; but the camp of supporters didn’t seem over the moon, either.

September 2, 2022 - Amiwest 2022 September Update 1
The show is 50 days out. Lots of great things happening. We are excited to announce that RJ Mical will be attending Amiwet in 2022. The schedule page has been updated with RJ and all our great presentors so far. In addition to the speakers we also have a new exhibitor showing several ReAmiga boards and his own C64 work.

Identify PAL inputs and outputs
In order to properly reverse engineer a PAL, you need to correctly identify which pins are inputs, and which pins are outputs. This in some cases is trivial because some of the PAL’s pin functions are fixed. Let’s look at the example of a PAL16L8.
Amiga Art Contest - 2022
Understand the system
Of all of the different techniques this one may be the simplest but also the most important.
When you’re trying to reverse engineer something, understanding the system is key to unraveling the black box which is the PAL. You need to understand what connects to the PAL on the inputs, what it connects to on the output side. Usually going one level back isn’t enough. Why? Because maybe the PAL connects to an OR gate, that then takes a couple other connections. So what you need to do is follow from the primary driver to the consumer of that signal.
Checkmate 1500 Mini case build with Pi4B and Greaseweazle V4
Recently I have been working on another new build project, this time using the recently released Checkmate A1500 Mini case, running a Raspberry Pi 4 with AmiKit XE.
Why simply “dumping” a PAL isn’t always possible?
Rom Dumping
Dumping ROMs is a pretty common practice in the space of reverse engineering, and many eeprom readers are cheap, easily available, and there’s really not much to them. Plunk your ROM chip in the reader, press, go, and you have a binary file with the contents. Provided that your reader supports the ROM chip, or you need an adapter like I built in this post to read Commodore Amiga ROMs in a TL866A:
New Reverse Engineering PALs page
I’ve recently put a new page online on the site. It hosts a basic outline on different techniques to enable one to reverse engineering a PAL, and produce a modern equivalent.
Right now, there are about a dozen topics/techniques, with no content beyond basic background information.
As time goes on, I’m going to add more and more posts, with the page serving as the outline, index, with centralized links.
Building the AA3000+ Part3 (Daughterboard)
Ok time to to the DB for the AA3000+
This is more or less “one stage”
First as usual: a board with all passives on:
I made a Locator for this instead of Hese file:
