Ultimate Amiga 1200: PiStorm, CD32 Mode and Full Hardware Expansion

Mon, 08 Jun 2026 21:15:04 +0000

Some time ago, I had the opportunity to get both an Amiga 500 and an Amiga 1200. While the Amiga 500 was restored as a fairly traditional machine, I had a more ambitious project in mind for the Amiga 1200.

My goal was to build three different machines into a single computer:

A high-end Amiga with a powerful CPU, graphics card, networking capabilities and all the modern conveniences normally associated with an upgraded Amiga 4000.
A more traditional Amiga 1200 with Fast RAM and a hard drive for maximum software compatibility.
A CD32-compatible system able to run games specifically enhanced for Commodore’s console, without requiring dedicated CD32 hardware such as the Akiko chip.

To achieve this, I combined several solutions:

Nintendo 64 : modded to output RGB

Tue, 14 Feb 2023 18:23:34 +0000

In a previous post, I shared how I converted my PAL Nintendo 64 to NTSC. The problem is that my CRT TV does not support NTSC composite signal, so an RGB mod was mandatory. I used Tim Worthington kit version 3.0.

I’m not going to explain what is already on the official install guide, I’m just sharing my experience…

Overview

Here is the N64 motherboard with what is in the kit : RGB board and wires:

PC-Engine DUO : RGB mod and jailbars fix

Thu, 03 Mar 2022 12:52:39 +0000

The video output of the original PC Engine DUO is composite only. Fortunately, the quality of its output is really good comparing to other consoles from the late 80’ / begining of 90’. But the signal is NTSC-J and if your display is not compatible, the picture will be in grey instead of colors. And that is the case of my old european CRT TV (a Grundig one). So I purchased an RGB kit from otakus-store and modded my DUO. The result is a nice and very sharp picture, but like many others I also had to fix the so called “jailbars” problem after this mod.
