It is not meant to be possible, and Sony would not be happy about it. Of course, anything is possible, but it's a lot of messing about. There are really two problems. 1. Bypassing the usual console program (which your Yaroze boots into) to load your program and data from the CD rather than the serial link. A PSX program exists which does this, and is located on Yaroze demo disks and PSM cover disks. However, it will take some severe hacking of the configuation files found on such disks to get it to work with your program. Sony obviously have a utility to do this, and have specs for the config file formats, but this is not available to us. Such hacking would be reverse engineering, and would be in violation of your Yaroze license. 2. Getting past the PSX copy protection. This again will take some hacking, and you'd need rip the copy protection sectors from a bootable PSX CD. Most CD writing software won't let you do this. Without this, the PSX won't even see your CD! Again, this would be in violation of your Yaroze license. So, even if you're up to it, it's a lot of effort, you'll probably scrap 50 or so CD-Rs in the process, and you'll be likely to get into all sorts of trouble with Sony. Maybe Sony would consider providing us with tools for making our own CDs. If we had boot disk (similar to the exising Yaroze boot disk) which loads the libraries and checks for the key card, and then requests that you insert a data disk (the data disk being a CD-R), then it would be possible. And Sony would not need to worry about us distributing to non-members, 'cos the CD-R would not be usable without the boot disk and key card. What do you think Sony? Or is there still the problem of copy protection code which will need to be written to the CD-R before the PSX will read it? Herbs
