CDTV advice?

Photon · 24 January 2022, 21:21

Again passion strikes. A friend came over to get a CDTV demo and once again it struck me this great tech was a royal gesture to tell anyone with any interest in technical things that Commodore-Amiga was a market leader.

From this gesture it doesn't matter how many or few who have it. The CDTV needs to have new game made for it. <3

Currently from a few minutes of googling I'm thinking new fan and a keyboard to start with, recent ROM patch and to write a CD to boot from floppy.

Hardware wise an A500+ and I'd hate to add requirements such as Fast RAM.

In this year we don't write CDs anymore and I'm looking for experience with how to:

Write CDs for CDTV in general and in detail
Trigger a CD audio track from running code

As a starting point. Add anything you want.

to trigger an audio track from running code, the best option atm is to use cdtv.device and the OS. But the resourced cdtv.device shows how to do it banging the hardware.

I have little to add other than what's been said, but generally I found burning CDs at the slowest possible rate which was 2X for me had a measurable improvement in the chances it would boot. Also buying "Music" CD-Rs.

Obviously WinUAE has decent CDTV support and that can be used. There are some issues around booting CDTVs without the TM file that are now resolved with CaptFuture's excellent OS 2.35 ROM.

The other thing worth checking out is CDXL. On CDTV you'll struggle at much more than 160x120 video, but reducing colours, doubling up and drawing every other vertical line might work to give the illusion of FMV. It'd probably work well played in a box on screen, say someone explaining the level objectives.

I've been meaning to do something with this but haven't had the time to get as far as I'd like. But if I can help in some way please drop me a DM.
