GET REAL
The impossible with just an upgraded hard drive setup?
As previously seen at VCF Midwest 2022, WAUG 2024 and my cringy early video on the
Greg Of Florida YouTube page
The demo you've been watching is a modernized version of Commodore's own patented "CDXL" audio/video playback technology, pushed to the absolute extreme.
This isn't some limited 150KB/sec low quality video with 1991's storage limits but rather a totally fluid, full-frame rate, NTSC overscan video with high-quality stereo audio. This is being done using the actual built-in Amiga's graphics and sound.
This targets real North American CRT TVs and monitors and their native 60Hz refresh rates.
This is your hub to learn more and do this yourself.
Please start with the history page or F.A.Q.
The "TL;DR" is ... In 1991, Commodore was awarded U.S. patent #5293606 for the invention of CDXL. Unfortunatly, this was before Commodore released the next-generation AGA-based Amiga computers. Fast forward to 2019 and Markus Schordan decided to extend CDXL and add AGA support. This targeted a windowed box of video on the screen. In early 2020, I discovered an exploit I could use to push this past the intended limits. This site depicts my journey, the results, and how you too can acheive them.

Do I actually need any of the things you suggest? No. A stock Amiga 1200 can play the same video files, but not at the same frame rate. If you seek the same result, then yes. However, this really does run on a stock Amiga 1200 - just not at full performance.
What is the full list of stuff to make this happen?
- An Amiga 1200 (4000 should work too) ‑ NTSC or PAL in NTSC mode
- A 68030 CPU board. A 68060 can work, but timings are TIGHTER so it is less forgiving. The stock 68020 can run the software but not at this speed.
- An Elbox Fast ATA controller card (link is for the 1200 version)
- Correct drivers
- An SSD (and IDE-SATA adapter)
- PFS3AIO filesystem
- Enable maximum data transfer rate via various options
- Degrader or similar (or my own tool) for disabling the audio high-pass filter
- AGAConv from Markus Schordan
- AGABlaster v0.9.71 (specifically and exactly this version)
- A Linux or WSL (on Windows) installation
- My personal scripts for preparing video and audio for this exploit, which feeds AGAConv. A mixture of need and convenience.
- Some Linux dependencies (over and above those required by Markus' tools)
- Enthusiasm!
If you want to play video at whatever capability your current Amiga can do as-is, I highly recommend simply checking out Markus' work.
